Feature questions, answered.
How does FreeSEO's keyword research compare to Semrush?▼
We use the same data quality (20B+ keywords across 142 databases) and surface volume, KDI, intent, CPC, and SERP features. The difference is price — FreeSEO is free; Semrush starts at $139.95/month. For users on the connector tier we wire live Semrush data straight into the dashboard.
What does the 140+ check site audit cover?▼
Technical (crawlability, indexing, sitemap, robots, hreflang, canonicals, HTTPS), on-page (meta titles, descriptions, H1s, image alt, internal linking, schema), performance (Core Web Vitals — LCP, INP, CLS), and mobile (viewport, tap targets, responsive). Every finding ranks high/mid/low impact.
Which AI engines does the AI visibility tracker monitor?▼
ChatGPT (GPT-5 family), Gemini (2.5 + 3 preview), Perplexity, and Google AI Overviews. We log brand mention frequency, citation rank, and sentiment for the prompts you target — the new SERP.
Does the WordPress auto-fix touch my live site directly?▼
Yes, via our lightweight WordPress plugin and an Application Password. Changes apply through the WP REST API with a full audit trail and one-click rollback. No FTP, no theme edits, no copy-paste.
Can I run audits at scale (bulk crawls)?▼
Yes. Pro plans crawl up to 25,000 pages per scan with parallel workers and a worst-offenders leaderboard. Free crawls cap at 100 pages — enough for a marketing site, blog, or small ecommerce catalog.
What integrations are available today?▼
WordPress (auto-fix), Google Search Console (live clicks/impressions/queries), Semrush (Pro connector for live keyword/backlink data). Webflow, Shopify, Ghost, GA4, and Slack are on the roadmap.
