## Where should you start?

1. Check access. Run the [visibility checker](https://usefulshelf.co/check) to inspect your server HTML and crawl rules.
2. Describe each page. Draft a search snippet, generate metadata, and add structured software details that match visible facts.
3. Make public pages discoverable. Publish a sitemap and review your robots.txt. Add llms.txt if a short reading guide would help your audience.

## How do these tools help SEO, AEO, and AI search?

SEO helps search engines discover and understand a website. Answer engine optimization (AEO) focuses on making information clear enough to answer a reader's question. Accurate page descriptions, readable HTML, useful answers, and consistent links support both tasks.

Google says its existing SEO practices also apply to AI search features; no special AI file or schema is required. These tools help with implementation, but do not guarantee indexing, traffic, citations, or recommendations.

## Are these tools free?

Yes. All 13 tools are free to use without an account. The 12 generators, counters, and previews process inputs in your browser. The visibility checker fetches your public website and saves a shareable report.
