SEO software: what they are and who makes them
Semrush, Ahrefs, SE Ranking and 6 more, sorted into types, with the company behind each and where it is based.
Types of SEO software
All-in-one search suites
Semrush, Ahrefs and SE Ranking combine keyword research, backlink analysis, site audits and rank tracking in one login. You pay one subscription with caps on projects, keywords and users. This fits in-house teams and agencies that want fewer tools to reconcile.
Crawlers and technical audit tools
Screaming Frog runs as desktop software and crawls a site the way a search engine does, listing broken links, redirects and duplicate titles. It suits technical specialists who audit large sites and do not need keyword or backlink data in the same product.
Budget and beginner-friendly toolkits
Mangools splits the work into small tools for keywords, SERP analysis, backlinks and tracking. Moz Pro sits between that and a full suite. Both suit freelancers and small businesses that want guided workflows and a lower monthly commitment. Neither asks for a sales call, and both publish their plan limits on the pricing page.
Specialist trackers and content optimizers
AccuRanker does daily rank tracking at scale, and Surfer scores pages against the top results while you write. Neither replaces a suite. They are add-ons for agencies tracking thousands of keywords or writers who optimize drafts. Pick them after the main suite is settled, because each solves a narrow problem and leaves keyword and backlink research to other products.
