SerpControl Ultra: SEO Audit & AI Shield

About

What it does

SerpControl Ultra puts eight on-page SEO tools inside the tab
you're already on. Click a tool in the popup, the audit opens
over the page, close it, it's gone. No new tab to load. No
dashboard to log into.

The eight tools:

Page Audit. A 9-section check, a 0–100 score, and every issue
listed with a one-line fix you can paste straight into the HTML.

AI Bot Shield. Reads your robots.txt and checks it against the
AI search, AI training, and SEO crawlers that matter. Hands you
a paste-ready snippet.

LLM Visibility. Refetches the page the way a non-JS bot reads
it, then diffs the raw HTML against the rendered DOM. You see
the page the way an AI crawler does versus the way a human does.

Schema Checker. Parses your JSON-LD and validates it against
schema.org, with type-specific rules for Article, Product,
LocalBusiness, FAQPage, HowTo, Recipe, Event, BreadcrumbList,
VideoObject, JobPosting, Review and AggregateRating.

Meta Inspector. Title, description, canonical, hreflang, OG,
Twitter Card, and a robots.txt path-allow check.

Headings. The H1 - H6 outline. Click any heading to jump to it on
the page. Flags missing H1 and skipped levels.

Link Map. Every link split internal vs external, deduped with
counts, optional broken-link scan if you want it.

Word Cloud. Top 100 words on the page, sized by frequency, with
the exact share of body text.

Why install it

Other tools tell you what's broken. That's useful, but you still
have to go figure out the fix. SerpControl writes the fix for
you. Every issue, in every tool, comes with a one-line action
you can paste into your HTML, your schema, or your robots.txt.
No "see docs" link to chase.

The other reason: nobody really tells you what AI crawlers see
on your page. Two of these eight tools exist for exactly that.
AI Bot Shield maps your robots.txt against the crawlers that
matter. LLM Visibility shows you the content an AI crawler
actually pulls when JavaScript doesn't run, which for most of
them, it doesn't.

How it works

Click a tool. The extension injects a self-contained script into
the active tab. The script reads the live DOM, runs the audit in
memory, renders an overlay on the page. Close the overlay and
it's gone. Nothing leaves your browser. We never see what you
audit.

Privacy

Manifest V3. Permissions: activeTab, scripting, storage. No
remote code. No analytics. No telemetry. The audit scripts only
run after you click a tool on the active tab.
