Top pick for serious SEO teams
Semrush

Semrush wins on breadth — keyword research, competitor analysis, site audits, content optimization, position tracking, and PPC research all in one platform. The keyword database is the largest in the category. Pro tier at $129.95/mo handles most small business needs without the per-user fees that Ahrefs charges.

The honest caveat: Semrush's data is broader than Ahrefs' but Ahrefs has the deeper backlink index. For pure link-building workflows, Ahrefs wins. Most small businesses don't need that depth — they need everything-in-one-place — and Semrush is the better choice for that workflow.

Questions

Google Search Console is free and essential — set it up first regardless of what else you use. For paid tools, Semrush's 7-day free trial is the best way to evaluate a comprehensive platform. If $129/month is too much, Mangools at $29/month covers keyword research and rank tracking adequately for most small businesses.
