Six tools for the checks an SEO runs every week. Four run entirely in your browser and send nothing anywhere; two fetch one URL from netweft's servers. None needs an account.

## Run in your browser

Nothing you type leaves the page.

- [SERP snippet preview](https://netweft.com/tools/serp-snippet-preview): See how a title and meta description fit a Google result, measured by width the way Google cuts them.
- [Robots.txt tester](https://netweft.com/tools/robots-txt-tester): Test whether a robots.txt allows a crawler to fetch a path, and see the rule that decided.
- [Schema markup generator](https://netweft.com/tools/schema-markup-generator): Fill in a form and get JSON-LD for an organization, an article, a product or a breadcrumb trail.
- [Hreflang generator](https://netweft.com/tools/hreflang-generator): Write and check hreflang tags for every language version of a page, as link tags or sitemap entries.

## Fetch one URL

netweft's servers fetch the one URL you give, behind a Cloudflare check.

- [SEO page checker](https://netweft.com/tools/seo-page-checker): Check one page against the single-page rules of netweft's site audit: title, description, headings, content and indexing.
- [Redirect checker](https://netweft.com/tools/redirect-checker): Follow a URL's redirects hop by hop and read the status code and headers of every answer.
