Ahrefs vs Semrush: which SEO tool should a small business pay for?

Ahrefs is the cleaner choice when backlink, competitor, keyword, and site research is the core job. Semrush currently combines SEO and AI Search in a broader plan. Both are expensive if nobody owns the monthly work.

Read the verdict

The short answer

Choose Ahrefs for focused SEO research. Choose Semrush when the broader SEO and AI Search package will be used.

Ahrefs currently offers a free verified-site entry, a $29 Starter tier, and Lite at $129 monthly. Semrush's current SEO plan is $139 monthly or $117.33 per month billed annually and includes SEO plus AI visibility features.

Decision rule: List the five monthly tasks first, then buy the tool that covers them with the least unused system.
