AI visibility: every visit from GPTBot, ClaudeBot, PerplexityBot and 15 other AI agents, measured server-side, page by page.
Hack The SEO does three things, free.
It shows you which AI crawlers read your pages, which pages they read, and when. No analytics tool can tell you that. It tells you what to fix so those pages are worth quoting. And it handles the whole technical SEO layer: schema, sitemaps, redirects, meta tags.
It also ships a read-only MCP server — the Model Context Protocol, the standard an AI client uses to read data from a tool. You connect Claude and ask about your site instead of clicking through screens.
You do not have to choose. Hack The SEO runs next to Yoast SEO, Rank Math, All in One SEO and SEOPress. It detects the one you already have, then steps aside on everything that plugin already produces. Nothing is printed twice, and you configure nothing. What it adds is what none of them gives you: the AI crawler log, the GEO score, the cannibalization report.
Why your analytics cannot see this. GPTBot, ClaudeBot and PerplexityBot do not run JavaScript, so a JavaScript analytics tool never sees them. Hack The SEO reads the request on your server, before any script runs, and writes every visit into a table in your own database.
/your-page.md, the plain format an AI model reads most reliably.Google-Extended is a robots.txt token, not a crawler, so counting it would count nothing.Other plugins give you a switch to block AI crawlers. This one tells you whether they came.
You do not have to do anything. Activate the plugin and let it sit: the crawlers come on their own and the screen fills up on its own. On a new site that can take weeks, and an empty screen is an answer too.
If you have a terminal and want to check today, ask your own server for a page while pretending to be GPTBot, then refresh the screen:
curl -A GPTBot https://your-site.tld/any-page/
Use a real post or page URL, not the home page: the detector only reads single pages. Everything here is built the same way: if we claim it, you can check it.
GEO, generative engine optimization (also called AEO), is the work of making a page a generative engine can read, understand and quote. Each page is scored out of 100 on six questions:
The rules are plain PHP in the plugin. Open the file and read them. No model decides your score, and no API key is involved.
The plugin ships a read-only MCP server. Connect Claude Code or Claude Desktop, and ask instead of clicking through screens:
Twelve abilities, and all twelve read. No write among them, and no setting that turns one on. Every call is made by a signed-in WordPress user and checks a capability, so drafts and password-protected content stay out. The connection is inbound: your client calls your site, and no third party is contacted. It needs WordPress 6.9, where the Abilities API entered core. The FAQ has the detail.
Keep it. Hack The SEO installs next to it and steps aside on its own.
The usual reason not to run two SEO plugins is duplicate output: two title tags, two canonicals, two sets of schema. This plugin is built to avoid exactly that, without you configuring anything.
Tested with Elementor, Divi, Bricks, Oxygen and WPBakery: it reads the rendered page, so scores and schema see what your visitors see. Multisite compatible. Works with caching plugins and CDNs, with one honest limit: a full-page cache that answers before WordPress loads also answers before this plugin runs, so those hits are not logged.
This plugin connects to two external services, neither used out of the box: IndexNow is off by default, and hacktheseo.com is contacted only when you submit the opt-in form.
What it is. IndexNow is an open protocol that lets a site notify participating search engines (Bing, Yandex, Naver, Seznam, Yep) that a URL has changed, instead of waiting to be crawled. The endpoint https://api.indexnow.org/indexnow is operated by the IndexNow sponsors: Microsoft Corporation, Yandex N.V. and Seznam.cz, a.s.
When it is used. Only when the IndexNow module is enabled. The option htsfree_indexnow_enabled defaults to 0. While it is 0, no hook is registered and no request is ever made. The plugin never enables it for you, including on activation. Once you enable it, a request is sent when you publish or update a post or page, or when you click the manual ping button in the admin.
What is sent. Only:
https://your-site.tld/{key}.txt, which is how the protocol proves you own the domain.No post content, no personal data, no visitor data, no site credentials and no administrator information are transmitted. Requests are rate-limited to one ping per URL per ten minutes.
Where to read their terms. Terms of use, which also contain the privacy statement for the service: https://www.indexnow.org/terms. Protocol documentation: https://www.indexnow.org/documentation. Microsoft’s privacy statement, as one of the sponsors processing submissions: https://privacy.microsoft.com/privacystatement.
What it is. hacktheseo.com is this plugin author’s site. It receives the email address you submit, at https://hacktheseo.com/wp-json/hts/v1/free-optin, and passes it to Klaviyo, the email service operated by Klaviyo, Inc. (United States), which stores the address and sends the guide and newsletter.
When it is used. Only when you type your email address in the opt-in form, tick the consent box and submit it. Never on activation, cron, a page view, or in the front end.
What is sent. Six fields and nothing else: email, the address you typed; consent, whether you ticked the box; consent_version, the wording you agreed to, currently 2026-09-optin-v1; source, the fixed word wp-plugin-free; plugin_version; and locale, your WordPress language code, for example fr_FR. The body carries no site name, no user name, no content, no settings, no scores, no AI crawler data, no visitor data, and no identifier of the plugin’s own. Outside the body, as on any WordPress request, the receiving server sees your IP address and the standard WordPress User-Agent, which contains your site address.
What happens next. The Klaviyo list is double opt-in: you are subscribed only after you click the link in its confirmation email. Every message carries an unsubscribe link.

When enabled, once a week your WordPress sends its administrator a short email through wp_mail(): AI crawler passages and pages, visitors arriving from AI chats, new broken links, and the movement of the site score. It uses your site’s existing mail configuration and contacts no third party. Nothing is sent on a week with nothing to report. Every email carries an unsubscribe link that works without logging in, and supports one-click unsubscribe from mail apps. It is off by default and controlled from the AI visibility settings.
The content performance module counts views, reading time and scroll depth for your published posts. This is stored in your own database only. Visitor IP addresses are never stored: they are hashed and used solely as a short-lived rate-limit key so the same visitor is not counted twice within thirty minutes. Nothing is sent anywhere. The module can be turned off with the option htsfree_visits_tracking.
Some features (the health check, the sitemap self-test, the schema verification, the redirect probe, page-builder content extraction) load a URL of your own site over HTTP, because that is the only reliable way to see what a visitor or a crawler actually receives. These are loopback requests to your own domain. They are not a third-party service, and nothing leaves your server.
