1. Keyword Research
Semrush: The Keyword Magic Tool is the centerpiece of Semrush’s keyword research. Enter a seed keyword and get thousands of related keywords with search volume, keyword difficulty, and cost-per-click data. The keyword gap tool shows terms your competitors rank for that you don’t. Keyword overview pages display SERP features, search intent, and keyword performance trends at a glance. Many users consider it the best SEO tool for finding specific keywords to target.
Similarweb: The Keyword Explorer shows keyword performance with search volume and competitive metrics. It focuses more on understanding the competitive landscape around keywords than generating content ideas. Keyword research is only available on the $335/month plan and above — the base plan does not include it.
2. Competitor Analysis
Semrush: The domain overview shows any competitor’s organic traffic, paid search spend, top keywords, and backlink count. The competitive research tools let you compare multiple domains side by side. You can also track competitor keyword rankings over time with position tracking.
Similarweb: Competitor analysis is Similarweb’s strongest feature. It shows total website traffic, traffic sources, engagement metrics, and audience demographics for any site. You can benchmark against up to 25 competitors at once. The web analytics data covers all channels — not just organic search. It also reveals ad strategies and competitive landscape details that Semrush doesn’t track.
3. Site Audit and Technical SEO
Semrush: The site audit tool crawls your website and flags technical SEO issues. It checks for broken links, slow pages, duplicate content, and crawl errors. The on-page SEO checker gives specific recommendations for each page. Pro allows auditing up to 100,000 pages per month.
Similarweb: Similarweb does not include a built-in site audit tool. You cannot crawl your own website for technical issues using this platform. If technical SEO matters to you, you’ll need a separate tool alongside Similarweb.
⚠️ Warning: If site audits are a core part of your workflow, Similarweb cannot replace Semrush or a dedicated audit tool. This is a major gap in Similarweb’s feature set for SEO professionals.
4. Backlink Analysis
Semrush: Backlink analytics shows referring domains, anchor text, and link authority. The backlink audit tool identifies potentially toxic links that could harm your rankings. The link building tool helps you find outreach opportunities based on competitor backlink profiles.
Similarweb: Backlink intelligence is available on the SEO-tier plans ($335/month and up). It shows referring domains and lets you analyze competitor link profiles. However, it doesn’t include a toxic link audit or disavow tool.
5. Content Marketing Tools
Semrush: The content marketing toolkit is available on Guru plans and above. It includes the SEO content template, topic research, SEO writing assistant, and content audit tools. These help you plan, write, and score SEO-friendly content from inside the platform. If content creation is central to your digital strategy, this toolkit sets Semrush apart from Semrush alternatives like Similarweb.
Similarweb: Similarweb does not include content marketing tools. There is no content editor, writing assistant, or content template builder. The platform focuses on data and intelligence, not content creation.
6. Rank Tracking and Position Monitoring
Semrush: Position tracking monitors target keywords daily across desktop and mobile. The Pro plan tracks 500 keywords. You can set up local tracking for specific cities and compare rankings against competitors on the same dashboard.
Similarweb: The rank tracker monitors keyword rankings and search engine positions. It’s available on the SEO-tier plans. While functional, Similarweb’s rank tracking focuses less on daily granularity and more on understanding broader keyword performance trends.
7. Market Research and Traffic Analysis
Semrush: Market research is available as an add-on called Traffic & Market Trends at $289/month. It’s not included in any standard plan. The organic traffic insights tool shows estimated traffic for your own site but doesn’t estimate competitor total traffic the way Similarweb does.
Similarweb: This is where Similarweb stands apart. Website traffic analysis breaks down traffic sources, engagement data, and audience demographics for any website. The market research tool tracks industry-wide trends, seasonal patterns, and emerging competitors. Similarweb aggregates clickstream data and web crawlers to deliver these estimates.
8. Pricing & Cost
Let’s compare the pricing plans side by side.
| Feature Level | Semrush | Similarweb |
|---|---|---|
| Entry Plan | $117.33/month (annual) | $125/month (annual) |
| Mid-Tier | $208.33/month (Guru) | $335/month (SEO bundle) |
| Top-Tier | $416.66/month (Business) | $540/month (Full bundle) |
| Free Trial | 7 days (Pro or Guru) | 7 days (limited) |
Semrush: The Pro plan at $117.33/month includes keyword research, site audit, position tracking, and backlink analysis. You get full SEO functionality from the entry plan. Adding the content marketing toolkit requires Guru at $208.33/month.
Similarweb: The $125/month plan covers traffic analysis and competitive benchmarking only. To get keyword research and rank tracking, you need the $335/month bundle. That makes Similarweb more expensive than Semrush if you need SEO features.
Different Scenarios

🛟 Support Options

What Our Review Didn’t Cover
This comparison focused on individual marketers and small teams. We didn’t test enterprise SSO, custom API integrations, or bulk user management features. Similarweb’s Sales Intelligence and Shopper Intelligence modules weren’t part of this review. Semrush’s new Semrush One bundle with AI Visibility tracking wasn’t evaluated in detail.
