Pricing Compared
Ahrefs pricing starts with a $29 Starter plan for basic keyword and competitor lookups. The main plans are Lite at $129, Standard at $249 and Advanced at $449 a month, each with one user included. Lite gives each user 1,000 credits a month, while Standard and Advanced have unlimited credits. Add-ons include Brand Radar for AI visibility from $199, a Content Kit from $99 and Report Builder at $99.
Semrush pricing now uses different plan names. The SEO plan is $139 a month for 5 websites and 500 daily tracked keywords. Starter is $199 with 50 AI prompts tracked daily, and Pro+ is $299 for 15 websites and 1,500 tracked keywords. Advanced is custom. AI visibility features are bundled into each plan rather than sold as a separate add-on.
For a solo consultant or small business, the realistic comparison is Ahrefs Lite at $129 against the Semrush SEO plan at $139. For more on how tool costs fit into an overall budget, see our guide to SEO cost.
Feature Comparison
Keyword Research
Both tools give search volume, keyword difficulty, related keywords, questions and SERP analysis. The numbers differ because each company uses its own data and models, so do not expect the same volume for the same keyword. Choose one tool and use it consistently. Our keyword research guide works with either.
Backlink Analysis
Backlink research is where Ahrefs built its name, and many SEOs still pick it first for link work. Semrush has a full backlink toolset too, including a backlink audit for finding risky links. If link building is a big part of your work, test both on a site you know well and compare which finds more of the links you expect.
Competitor Research
Both let you enter any domain and see its top pages, keywords and traffic estimates. Semrush also covers paid search ads and advertising research, which helps if you run Google Ads. Ahrefs focuses on organic search. See our SEO competitor analysis guide for a process that works in either tool.
Site Audit
Both crawl your site and report technical issues such as broken links, redirect chains, missing tags and slow pages. Ahrefs Free includes Site Audit for verified site owners, which makes Ahrefs the easier free option for checking your own site. Pair either with our technical SEO checklist.
Rank Tracking
Ahrefs Lite tracks 750 keywords and Standard tracks 2,000. Semrush’s SEO plan tracks 500 keywords daily and Pro+ tracks 1,500. Compare these limits with the number of keywords you actually need to watch.
AI Search Visibility
This is the newest battleground. Ahrefs Brand Radar researches brands across a large AI prompt database and tracks custom prompts, but it costs extra. Semrush includes AI visibility tracking, sentiment and prompt tracking in its plans. We compare these and other options in our guide to AI visibility tools.
Local SEO
Semrush has a long-standing local toolkit for listing management and local rank tracking. Ahrefs lists a Google Business Profile monitor in beta on its Lite plan. If your clients are mostly local businesses, this point leans toward Semrush. Our guide to local citations covers what those listing tools manage.
Which Should You Choose?
Choose Ahrefs if:
- Backlink research and link building are core to your work.
- You want a strong free tool for auditing your own site.
- You prefer a cleaner tool focused on organic search.
Choose Semrush if:
- You also manage Google Ads, social media or local listings.
- You want AI visibility tracking included without a separate add-on.
- You need to track more websites on one entry-level plan.
Try both if you can. Use Semrush’s free trial and the Ahrefs Starter plan for a month on the same project, and keep the one that answers your questions faster.
Can You Do SEO Without Either Tool?
Yes. Google Search Console, Google Analytics, Ahrefs Free and the Semrush Free plan cover a lot of ground for one site. Paid tools mainly save time and show competitor data you cannot get elsewhere. For a small business with one site, free tools plus clear priorities often beat an expensive subscription used once a month.
