Frequently Asked Questions

Can I run a full technical SEO audit for free?

Yes. The Website Crawler and Broken Link Checker walk your pages and report the issues that most often block rankings — broken internal links, missing metadata and crawl problems — without a paid subscription.

How is keyword research different from keyword clustering?

Keyword research finds the terms people search for and how competitive they are. Keyword clustering then groups those terms into topics so one page can target a whole cluster instead of a single phrase.

Do these SEO tools work on any website?

They work on publicly reachable pages. Sites that block crawlers, sit behind a login, or render everything client-side may return partial data.

How often should I re-run an audit?

After every significant content or template change, and otherwise monthly. Re-running on a schedule catches regressions that appear when you publish new pages or redesign a template.
