Semrush is the industry standard for SEO — keyword research, backlink analysis, site audits, competitive intelligence — it does everything. But at $139.95/month for the Pro plan (and $249.95 for Guru), it’s painfully expensive for freelancers, small agencies, and bootstrapped startups. The question isn’t whether Semrush is good. It’s whether you can get 80% of its value for 20% of the cost.
After testing dozens of tools over the years, here are the 10 best Semrush alternatives that actually deliver — along with honest comparisons of their features, pricing, and where each one shines or falls short.
Quick Comparison: Semrush vs Top Alternatives

Before we get into the details, here’s a side-by-side snapshot of how these tools compare on the metrics that matter most:
| Tool | Starting Price | Free Plan? | Best For | Database Size |
|---|---|---|---|---|
| Semrush | $139.95/mo | Limited free | All-in-one SEO | 26B+ keywords |
| Ahrefs | $129/mo | Free webmaster tools | Backlink analysis | 28B+ keywords |
| Moz Pro | $49/mo | Free tools available | Domain Authority, local SEO | 500M+ keywords |
| Ubersuggest | $29/mo | Yes (limited) | Budget-friendly keyword research | Not disclosed |
| SE Ranking | $65/mo | 14-day trial | Rank tracking | 4.4B+ keywords |
| SpyFu | $39/mo | Limited free | PPC & competitor analysis | 109M+ domains |
| Mangools | $29.90/mo | 10-day trial | Beginner-friendly keyword research | 2.5B+ keywords |
| Serpstat | $59/mo | Free plan (limited) | Multi-purpose SEO on a budget | 7B+ keywords |
| KeywordTool.io | $89/mo | Free (no volume data) | Long-tail keyword discovery | Not disclosed |
| Majestic | $49.99/mo | Limited free | Backlink index & link building | Largest link index |
| Screaming Frog | $259/year | Free (500 URLs) | Technical SEO audits | N/A (crawler) |
Now, here’s the detailed breakdown of each tool and when it genuinely makes sense over Semrush.
1. Ahrefs — The Closest Full-Featured Alternative
If there’s one tool that goes head-to-head with Semrush on every major feature, it’s Ahrefs. Their backlink index is arguably the best in the industry, their keyword explorer covers 10 search engines, and their content explorer helps you find link-worthy topics. For a deep dive into Ahrefs’ capabilities, read our comprehensive Ahrefs review.
Key Features
- Site Explorer: The crown jewel. Shows any domain’s organic traffic, top pages, backlink profile, and referring domains with extreme granularity.
- Keywords Explorer: Covers Google, YouTube, Amazon, Bing, Yahoo, and more. Keyword difficulty scores are considered more accurate than Semrush’s by many SEO professionals.
- Content Explorer: Unique feature — search a topic and find the most shared/linked content across the web. Invaluable for content strategy and link building outreach.
- Site Audit: Crawls your site for technical issues with clear prioritization and fix recommendations.
- Rank Tracker: Tracks keywords across desktop and mobile, with competitor comparison built in.

Pricing
Ahrefs Lite starts at $129/month, which is slightly cheaper than Semrush Pro. The Standard plan ($249/month) is comparable to Semrush Guru. There’s no free plan, but Ahrefs Webmaster Tools gives you free access to Site Explorer and Site Audit for your verified sites.
Verdict: Ahrefs vs Semrush
Ahrefs has the better backlink database and a cleaner UI. Semrush has stronger PPC tools, a more comprehensive content marketing toolkit, and better social media tracking. If backlink analysis and content research are your priorities, Ahrefs wins. If you need an all-in-one marketing platform, Semrush has the edge. For affordable access, consider an Ahrefs group buy to test the full suite without the $129/month commitment.
2. Moz Pro — Best for Domain Authority and Beginners
Moz literally invented Domain Authority (DA), the metric that most marketers still use to evaluate website strength. While Moz has fewer features than Semrush or Ahrefs, what it does, it does well — and the user experience is noticeably more welcoming for beginners. Check out our full Moz review for a detailed look at what it offers.
Key Features
- Domain Authority & Page Authority: Still the most widely-used authority metrics in the SEO industry, despite competitors launching their own versions.
- Keyword Explorer: Includes organic CTR estimates and a priority score that combines volume, difficulty, and opportunity — genuinely helpful for filtering keywords.
- Link Explorer: Solid backlink analysis with spam score detection, though the index is smaller than Ahrefs or Majestic.
- On-Page Optimization: Gives you page-specific recommendations to improve rankings for target keywords.
- MozBar Browser Extension: Free Chrome extension that shows DA/PA directly in search results. Hugely popular among SEO professionals.
Pricing
Moz Pro starts at $49/month (Starter plan), making it one of the most affordable mid-tier SEO tools. The Standard plan is $99/month, Medium is $179/month, and Large is $299/month. They also offer a 30-day free trial with full access.
Verdict: Moz vs Semrush
Moz is significantly cheaper and easier to learn, but its keyword database is much smaller (500M+ vs 26B+) and its backlink index trails Ahrefs and even Semrush. For local SEO, Moz Local is a standout feature that neither Semrush nor Ahrefs match well. Best for: beginners, local businesses, and teams that primarily need DA-based analysis.
3. Ubersuggest — Best Budget Option for Solopreneurs
Neil Patel’s Ubersuggest has evolved from a simple keyword tool into a surprisingly capable SEO platform — and it’s one of the few tools that offers a lifetime deal alongside its monthly pricing.
Key Features
- Keyword Research: Volume, CPC, competition score, and seasonal trends. The interface is clean and beginner-friendly.
- Domain Overview: Shows any domain’s organic traffic, top keywords, and backlink count. Less detailed than Ahrefs or Semrush, but serviceable.
- Site Audit: Checks for basic technical SEO issues — page speed, meta tags, broken links, mobile usability.
- Content Ideas: Shows top-performing content for any keyword, sorted by social shares and backlinks.
- AI Writer: Built-in AI content generation (a recent addition that’s surprisingly usable for drafts).
Pricing
Individual plan starts at $29/month or $290 lifetime (one-time payment). Business plan is $49/month or $490 lifetime. Enterprise is $99/month or $990 lifetime. The lifetime pricing is Ubersuggest’s killer advantage — it pays for itself within 10 months.
Verdict: Ubersuggest vs Semrush
Ubersuggest covers maybe 30-40% of Semrush’s feature set, but at roughly 20% of the price (or zero ongoing cost with the lifetime deal). The data accuracy isn’t as reliable — keyword volumes and traffic estimates can be off by significant margins. But for bloggers, solopreneurs, and small businesses doing basic keyword research and site auditing, it’s genuinely sufficient.
4. SE Ranking — Best Value All-in-One Platform
SE Ranking is the under-the-radar choice that keeps gaining market share. It offers a feature set surprisingly close to Semrush — keyword research, competitive analysis, backlink monitoring, site audits, social media management — at roughly half the price.
Key Features
- Rank Tracker: Arguably SE Ranking’s strongest feature. Daily updates, local tracking, Google Maps tracking, featured snippet monitoring.
- Keyword Research: 4.4 billion keyword database with volume, difficulty, CPC, and SERP features data.
- Competitive Analysis: Shows organic and paid keywords, traffic estimates, and top pages for any domain.
- Backlink Checker & Monitor: Find backlinks to any domain and monitor your own link profile over time.
- Website Audit: 120+ checks for technical, on-page, and content issues with clear priority scoring.
- Content Marketing Module: AI-powered content editor with SEO scoring (similar to Surfer SEO or Clearscope).
Pricing
SE Ranking starts at $65/month for the Essential plan (tracking 500 keywords). Pro is $119/month and Business is $259/month. They also offer flexible pricing where you can reduce costs by checking rankings every 3 days instead of daily, dropping the Essential plan to as low as $44/month.
Verdict: SE Ranking vs Semrush
SE Ranking is the best Semrush alternative for people who want a full-featured platform without the premium price tag. The database is smaller, but for most SEO work — especially for sites targeting English-speaking markets — the data is perfectly adequate. The rank tracking is actually superior to Semrush’s in terms of update frequency and granularity.
5. SpyFu — Best for PPC and Competitor Keyword Spying
SpyFu was built specifically for one thing: seeing exactly what your competitors are doing in search, both organic and paid. While other tools have added competitive analysis features over time, SpyFu still has the deepest historical data.
Key Features
- Competitor Keyword Analysis: See every keyword a competitor has ever ranked for or bid on, going back 18+ years.
- PPC Research: View competitors’ ad copy, ad spend estimates, most profitable keywords, and historical ad variations. This is where SpyFu genuinely has no equal.
- Keyword Grouping: Automatically clusters related keywords into groups, saving hours of manual organization.
- Backlink Outreach: Identifies link building opportunities based on competitors’ backlink profiles.
- SEO Reports: Generates white-label reports that agencies can send to clients.
Pricing
Basic plan starts at $39/month. Professional is $79/month. Team is available for custom pricing. All plans include unlimited searches and exports — no credit-based restrictions.
Verdict: SpyFu vs Semrush
SpyFu is better and cheaper for PPC competitive intelligence. If Google Ads is a significant part of your marketing, SpyFu’s historical ad data and keyword profitability metrics are unmatched. For organic SEO, it’s functional but less comprehensive than Semrush, Ahrefs, or even SE Ranking.
6. Mangools — Best Beginner-Friendly SEO Suite
Mangools packages five SEO tools into one affordable subscription: KWFinder, SERPChecker, SERPWatcher, LinkMiner, and SiteProfiler. The standout feature is KWFinder, which many SEO professionals consider the most intuitive keyword research tool available.
Key Features
- KWFinder: Beautiful interface for finding low-competition keywords. Shows search volume, trend, CPC, and keyword difficulty with a color-coded system that instantly tells you whether a keyword is worth targeting.
- SERPChecker: Analyzes the SERP for any keyword, showing the authority metrics of all ranking pages so you can quickly assess competition.
- SERPWatcher: Simple, visual rank tracking with daily updates and performance alerts.
- LinkMiner: Backlink analysis with page preview — you can see the exact page context of each backlink without leaving the tool.
- SiteProfiler: Quick domain overview with authority metrics, top content, and competitor identification.
Pricing
Mangools Entry starts at $29.90/month (or $19.90/month billed annually). Basic is $44.90/month, and Premium is $89.90/month. The Entry plan includes 100 keyword lookups/day and 200 keyword suggestions/search — enough for most individual users.
Verdict: Mangools vs Semrush
Mangools trades depth for usability. You won’t get Semrush’s massive database, content marketing tools, or PPC features. But if your primary needs are keyword research and rank tracking, KWFinder is arguably better than Semrush’s keyword tool for finding easy-to-rank opportunities. Perfect for bloggers and niche site builders.
7. Serpstat — Best Budget All-in-One for Agencies
Serpstat positions itself as a “growth hacking tool for SEO, PPC, and content marketing.” It covers most of Semrush’s feature categories at a lower price point, though the data depth isn’t as extensive.
Key Features
- Keyword Research: 7 billion keyword database with search volume, keyword difficulty, CPC, and related keyword suggestions.
- Site Audit: Crawls up to 100,000 pages (on higher plans) checking for 60+ technical SEO issues.
- Rank Tracker: Daily rank monitoring with competitor tracking and visibility trend analysis.
- Backlink Analysis: Shows backlink profile, referring domains, and anchor text distribution for any domain.
- Keyword Clustering: Groups keywords by search intent based on SERP similarity — a unique feature that saves significant time in content planning.
- AI Content Tools: Built-in AI-powered content creation and optimization suggestions.
Pricing
Individual plan starts at $59/month. Team is $119/month, Agency is $479/month. They offer a limited free plan (10 searches/day) that’s useful for basic checks but not serious work. Annual billing drops prices by about 20%.
Verdict: Serpstat vs Semrush
Serpstat covers most of Semrush’s ground at 40-50% of the price. The keyword clustering feature is genuinely innovative and not available in Semrush without third-party tools. However, the US keyword database is less comprehensive, and the interface can feel cluttered compared to Semrush or Ahrefs. Best for agencies managing multiple client sites who need broad functionality without premium pricing.
8. KeywordTool.io — Best for Long-Tail Keyword Discovery
KeywordTool.io is a specialist, not a generalist. It does one thing exceptionally well: generating massive lists of long-tail keyword suggestions from Google Autocomplete, YouTube, Bing, Amazon, eBay, Instagram, Twitter, Pinterest, and the App Store.
Key Features
- Autocomplete Keyword Generation: Generates up to 750+ keyword suggestions per seed keyword by mining autocomplete data from multiple platforms.
- Multi-Platform Coverage: Unlike Semrush (which focuses on Google), KeywordTool.io pulls suggestions from 8+ platforms — invaluable for e-commerce, YouTube, and app marketing.
- Question-Based Keywords: Filters for questions (what, how, where, why) that are perfect for FAQ content and featured snippet targeting.
- Competitor Analysis: Pro plans let you see keywords any website ranks for (similar to Semrush, but with less depth).
Pricing
The free version generates keyword suggestions but hides search volume, CPC, and competition data. Pro Basic starts at $89/month, Pro Plus is $99/month, and Pro Business is $199/month. These prices are higher than you’d expect for a single-purpose tool.
Verdict: KeywordTool.io vs Semrush
This isn’t a Semrush replacement — it’s a complement. KeywordTool.io finds long-tail keywords that Semrush’s Keyword Magic Tool misses, especially for non-Google platforms. Use it alongside your primary SEO tool for deeper keyword discovery, particularly for content ideation and YouTube/Amazon keyword research.
9. Majestic — Best for Pure Backlink Analysis
Majestic has the largest backlink index on the planet. While other tools have expanded into keyword research and content tools, Majestic stays laser-focused on links. Their proprietary metrics — Trust Flow and Citation Flow — are industry standards alongside Moz’s DA.
Key Features
- Fresh Index & Historic Index: Two separate backlink databases — the Fresh Index (updated daily) and the Historic Index (going back years). The Historic Index is uniquely valuable for seeing link building patterns over time.
- Trust Flow & Citation Flow: Majestic’s proprietary metrics. Trust Flow measures backlink quality; Citation Flow measures quantity. The ratio between them tells you a lot about a site’s link profile health.
- Topical Trust Flow: Categorizes backlinks by topic, showing whether a site’s authority is topically relevant — a dimension most other tools ignore.
- Clique Hunter: Finds sites that link to multiple competitors but not to you — essentially automating link building prospecting.
- Bulk Backlink Checker: Check backlink metrics for up to 1 million URLs at once.
Pricing
Lite plan starts at $49.99/month. Pro is $99.99/month, API plan is $399.99/month. The Lite plan is sufficient for freelancers and small sites. Pro unlocks the Historic Index, which is essential for competitive analysis.
Verdict: Majestic vs Semrush
Majestic is better than Semrush for backlink analysis, specifically for link building campaigns, link profile auditing, and competitive backlink research. It has no keyword research, rank tracking, or site audit features. It’s a specialized tool that pairs well with a keyword-focused tool like Mangools or Ubersuggest.
10. Screaming Frog — Best for Technical SEO Audits
Screaming Frog SEO Spider is a desktop crawler that audits websites for technical SEO issues. It’s not a cloud-based SaaS platform like Semrush — it’s a downloadable program that runs on your computer, which gives it unique advantages in speed, customization, and data depth.
Key Features
- Full Site Crawling: Crawls every URL on your site, checking status codes, redirects, meta tags, headings, canonicals, hreflang, and more.
- JavaScript Rendering: Can render JavaScript-heavy pages to crawl them as Google would see them — critical for SPAs and React/Angular sites.
- Structured Data Validation: Checks schema markup for errors and warnings, something most cloud-based tools handle poorly.
- Custom Extraction: Extract any data from your pages using XPath, CSS selectors, or regex — incredibly powerful for auditing specific elements.
- Integration with GA4 & Search Console: Pulls in traffic and performance data alongside crawl data, so you can prioritize fixes by impact.
- Log File Analysis: Analyze server logs to see how Googlebot actually crawls your site — reveals crawl budget issues that no other tool can detect.
Pricing
The free version crawls up to 500 URLs — enough for small sites. The paid license is $259/year (not monthly), unlocking unlimited crawling and all advanced features. That works out to about $21.58/month, making it one of the cheapest SEO tools available.
Verdict: Screaming Frog vs Semrush
Screaming Frog’s site audit is significantly more powerful and customizable than Semrush’s built-in audit tool. It finds issues Semrush misses and gives you raw data you can analyze however you want. The downside: it does nothing else — no keyword research, no backlink analysis, no rank tracking. It’s an essential tool in any technical SEO’s toolkit, but it’s a complement to Semrush, not a replacement.
How to Choose the Right Semrush Alternative
The “best” alternative depends entirely on your situation. Here’s a decision framework:
Choose Based on Your Primary Need
| If You Primarily Need… | Best Choice | Why |
|---|---|---|
| Full Semrush replacement | Ahrefs or SE Ranking | Closest feature parity at competitive pricing |
| Budget keyword research | Mangools or Ubersuggest | Under $30/mo with solid keyword data |
| Backlink analysis | Ahrefs or Majestic | Largest and most accurate link databases |
| PPC competitor intelligence | SpyFu | Deepest historical PPC data available |
| Technical SEO auditing | Screaming Frog | Most powerful crawling and analysis tool |
| Beginner-friendly interface | Moz Pro or Mangools | Cleanest UX with guided workflows |
| Agency with many clients | Serpstat or SE Ranking | Good multi-project support at agency-friendly pricing |
The Group Buy Strategy
Here’s something most comparison articles won’t tell you: you don’t always have to choose just one tool. Through Semrush group buy services like Toolsurf, you can access Semrush and other premium SEO tools at a fraction of the retail price. This is particularly useful for freelancers and small agencies who need occasional access to premium features without committing to $140+/month subscriptions.
Group buy access lets you run competitive analyses, pull backlink data, and do deep keyword research when you need it — without the ongoing cost. Many SEO professionals use this approach to supplement a cheaper primary tool (like Ubersuggest or Mangools) with periodic access to premium platforms.
The Power Combo Approach
Instead of finding one tool that does everything, many experienced SEOs combine specialized tools:
- Mangools ($30/mo) for keyword research + Screaming Frog ($22/mo) for technical audits = $52/month for capabilities that rival Semrush in their respective areas
- Ubersuggest (lifetime $290) for daily keyword research + Majestic ($50/mo) for link building = one-time + $50/month with best-in-class link data
- SE Ranking ($65/mo) as your all-in-one + SpyFu ($39/mo) for PPC intelligence = $104/month for broader coverage than Semrush alone
This modular approach often gives you better data in each category than any single all-in-one tool, and you can swap out components as your needs change.
Features Comparison: What Semrush Does That Alternatives Often Miss
Before you switch, know what you might lose. Semrush has a few features that are hard to replicate elsewhere:
- Listing Management: Manage business listings across 70+ directories from one dashboard. Only Moz Local competes here.
- Social Media Toolkit: Schedule posts, track engagement, and analyze competitors’ social presence. Most SEO tools skip this entirely.
- Content Marketing Platform: Topic research, SEO writing assistant, content audit, and brand monitoring in one workflow.
- Market Explorer: Analyze entire market segments, not just individual competitors. Shows market size, traffic sources, and audience demographics.
- .Trends Add-on: Competitive intelligence tool showing traffic and engagement data for any domain — powered by clickstream data.
If you rely heavily on any of these features, switching to an alternative means finding separate tools for each capability, which adds complexity and potentially cost.
⚖️ ToolSurf Verdict
There’s no single tool that replaces Semrush feature-for-feature. Ahrefs comes closest but costs nearly the same. For genuine savings, SE Ranking ($65/mo) and Mangools ($30/mo) deliver the best value depending on whether you need a full suite or focused keyword research. The smartest approach for most SEO professionals is combining a budget primary tool with group buy access to premium platforms like Semrush and Ahrefs through Toolsurf — giving you the best data when you need it without the $140+/month ongoing commitment. Whatever you choose, avoid the trap of paying for features you never use. Audit your actual workflow first, then pick the tool that covers those specific needs.
Frequently Asked Questions
What is the best free alternative to Semrush?
Ubersuggest offers the most generous free tier among Semrush alternatives, providing limited keyword searches, domain overviews, and site audit functionality without paying. Google Search Console combined with Google Keyword Planner is a completely free combination that covers basic keyword data and site performance monitoring. For backlink analysis, Ahrefs Webmaster Tools gives you free access to your own site’s backlink profile and site audit.
Is Ahrefs better than Semrush?
Neither is objectively “better” — they excel in different areas. Ahrefs has a larger and more accurate backlink index, better content explorer, and a cleaner interface. Semrush has stronger PPC tools, a more comprehensive content marketing platform, social media management, and a larger keyword database. For pure SEO work (keyword research, backlinks, rank tracking), they’re roughly equivalent. For broader digital marketing needs, Semrush offers more under one roof.
Can I use Semrush for free?
Semrush offers a limited free account that gives you 10 searches per day, access to basic domain analytics, and the ability to track 10 keywords. It’s useful for occasional checks but not practical for daily SEO work. They also offer a 7-day free trial of the Pro plan with full access. For extended access without the full subscription cost, Semrush group buy options through Toolsurf provide affordable alternatives.
Which Semrush alternative is best for small businesses?
SE Ranking or Ubersuggest are the best options for small businesses. SE Ranking offers nearly all of Semrush’s feature categories at roughly half the price, with flexible pricing that lets you reduce costs further by choosing less frequent rank checking. Ubersuggest is even cheaper and offers a lifetime pricing option that eliminates ongoing costs entirely — ideal for small businesses with limited marketing budgets.
How does Moz compare to Semrush for local SEO?
Moz is actually better than Semrush for local SEO. Moz Local lets you manage business listings across 70+ directories, monitor reviews, and ensure NAP consistency — all from one dashboard. Moz’s local search ranking factors research is also the most cited in the industry. Semrush has a listing management add-on, but it’s less mature and costs extra on top of your Semrush subscription.
What is the cheapest Semrush alternative with good data?
Mangools at $29.90/month (or $19.90/month annually) offers the best balance of affordable pricing and reliable data quality. KWFinder’s keyword difficulty scores are well-regarded, and the 2.5 billion keyword database is large enough for most research needs. Ubersuggest at $29/month is comparable but with the added advantage of a $290 lifetime plan.
Should I use multiple SEO tools instead of Semrush?
Yes, this is often the smartest approach. Combining specialized tools (e.g., Mangools for keywords + Screaming Frog for audits + Majestic for backlinks) can give you better data in each category than any single all-in-one tool, often at a lower total cost than Semrush. The tradeoff is managing multiple interfaces and subscriptions, which adds some workflow complexity. Start with one primary tool and add specialists as you identify specific data gaps.
Do group buy SEO tools provide full Semrush access?
Group buy services like Toolsurf provide access to Semrush and other premium SEO tools at significantly reduced costs — typically $10-30/month instead of $140+. The access is shared, which means there may be limitations on simultaneous usage or certain features. For SEO professionals who need occasional deep-dive research rather than constant daily access, group buy tools offer an excellent cost-to-value ratio. They’re particularly useful for freelancers and small agencies who can’t justify multiple $100+/month tool subscriptions.
