SEO Spider Tools is SpiderNow's free extension for one page's indexing rules, links, redirects, status codes, speed, tags, hreflang and schema, with a text editor and an .htaccess builder on the side. Full-site scans are sold on SpiderNow's website from $6.99 a month, the listing doesn't say whether the extension needs an account, and it hasn't been updated since October 2023. - **Value for money: A.** Free from the Chrome Web Store, which lists no in-app purchases. SpiderNow's site scans are sold separately, from $6.99 a month. - **Free plan and trial: A.** Free outright as far as the store shows: every check, the content editor and the .htaccess builder. The listing can't say whether it needs a SpiderNow account. - **Features: C.** Robots and meta directives, links with follow status, broken links and redirect chains, status codes, Core Web Vitals, titles, headings, canonical, hreflang, schema errors and thin pages. The gap the listing names: one page at a time, with full-site scans sold separately. - **Ease of use: B.** No rating on record, and nothing to set up is on record: install it and open the panel on a page. - **Platforms and integrations: C.** Chrome and Edge, so computers only. It pulls Core Web Vitals from PageSpeed Insights, and nothing else is listed. These are ToolGPA's own grades.

And it is not the kind of software a weekend replaces. - You could make: Schema markup and internal linking: an app builder makes these well. - You could not: A crawler that checks every page of a site. - You could not: Speed tests run from real browsers on a schedule. A judgement by ToolGPA from this listing, by rules that are the same for every tool. Nothing was built to test it. ## Works with PageSpeed Insights **Tags:** Site audit, Page speed, Schema markup, Internal linking ## Alternatives - [Checkbot](https://toolgpa.com/tools/checkbot): Chrome extension that crawls a site for SEO, speed and security issues.
