FAQ
What is the best free SEO audit tool?
Google Search Console is the best free SEO audit tool for most websites. It is directly connected to how Google indexes your site, flags crawl errors, coverage issues and Core Web Vitals failures, and costs nothing. Screaming Frog's free tier, which crawls up to 500 URLs, is the best free option for a full technical crawl.
Is Screaming Frog good for SEO audits?
Screaming Frog SEO Spider is one of the most widely used tools for technical SEO audits. The paid licence costs £149 per year and removes all crawl limits, making it practical for sites of any size. It is particularly strong for identifying redirect chains, duplicate content, broken links and missing meta tags.
Do I need a paid SEO audit tool?
Not necessarily. For small sites with under 500 pages, the combination of Google Search Console, Google PageSpeed Insights and the free tier of Screaming Frog covers the most important checks at no cost. Paid tools become worthwhile when you need scheduled crawls, white-label reports, historical tracking or integration with keyword and backlink data.
Which SEO audit tool is best for freelancers?
SE Ranking and Sitebulb are both well-suited to freelance SEO consultants. SE Ranking offers white-label PDF reports and starts at around £44 per month, while Sitebulb produces strong visual reports that work well in client presentations. Screaming Frog paired with a free Google Data Studio template is a lower-cost alternative for consultants who prefer to build their own reports.
