Overview
SEO Helpers focuses on the parts of technical SEO you can verify without crawling a site: how a title and description will truncate, what a shared card looks like, whether a slug normalises cleanly, and whether robots and sitemap files say what you intended. These are drafting and review aids, not rank trackers or audit suites.

Why these tools
Most avoidable indexation problems are authoring problems—an over-long description, an accidental disallow, a canonical pointing at the wrong variant. Previewing and generating those artefacts locally catches the mistake before it reaches a crawler.

Frequently asked questions
- Do these tools crawl my live site?
- No. They work on the text and URLs you paste, which keeps them fast and private but means they cannot detect server-side issues. Pair them with a real crawler for full audits.
- How long should a meta description be?
- Around 150–160 characters is a practical target, though search engines truncate by rendered width. Meta Tag Preview shows where the cut-off lands for your text.
- Is keyword density still worth measuring?
- As a readability signal, occasionally. As a ranking lever, no. Use it to notice unintentional repetition rather than to hit a percentage target.
- Can I generate a full sitemap here?
- Sitemap XML Generator builds a valid urlset from a list of absolute URLs with optional lastmod and priority. Large sites should generate sitemaps in their build pipeline instead.
- What does the canonical checker actually verify?
- It applies client-side heuristics to the page and canonical URLs you paste—protocol, host, and trailing-slash mismatches—without fetching either page.
