Details
Ahrefs tells you three things: what your competitors rank for, what backlinks they have, and what keywords you have a realistic chance of ranking for. That is the information you need to decide if organic search is worth pursuing for your business.
At $99/month, this is not a casual purchase. But if organic traffic is a key part of your growth strategy, Ahrefs pays for itself by keeping you from wasting months targeting keywords you will never rank for. Try their free webmaster tools first to see if the data is useful for your situation before committing to a paid plan.
Semrush covers keyword research, backlink and competitor analysis, daily rank tracking and technical site audits, and it now also tracks how your brand shows up in AI answers and AI search.
It suits founders for whom search is the main growth channel and who will open it every week. Google Search Console, which is free, already covers your own site’s search data, so start there if you only need that.
Adobe completed its purchase of Semrush in April 2026. Semrush has told existing customers that their services and contracts are not changing for now.
