Not always. Most people start with the tool that matches the immediate problem, such as robots.txt for crawl rules or a sitemap for discovery.
Can I use these outputs directly on a live website?
Yes, but you should still review the result before publishing. The best output is the one that matches your actual site structure and content.
Who is this toolkit for?
It works best for small website owners, indie hackers, marketers, and lean teams that want clear technical SEO help without heavy enterprise software.
