Malaysian SEO agency launches free tool that grades Google-backed SEO advice

Mackyclyde SEO has released CiteCheck, a free browser extension that labels on-page and AI-search checks by their evidence level, including whether Google has documented them, research supports them, or they are just industry consensus. The company says the tool is meant to help users separate confirmed rules from widely repeated claims that have never been verified by search engines.

Why it matters: - CiteCheck tries to answer a growing problem in SEO and AI search: which advice is actually documented and which advice is just repeated until it sounds true. - The tool could help businesses avoid treating unverified tactics as hard rules, especially as more agencies push site changes for AI visibility. - The release also reflects a broader shift toward evidence-based SEO as companies look for clearer standards.

What happened: - Mackyclyde SEO released CiteCheck free for Chrome, Edge and Brave. - The browser extension runs 50 on-page and AI-citability checks on any page. - Each check is tagged by evidence tier: documented by a search engine, supported by published research, industry consensus, or informational only. - Every tag includes a source link, or a clear note that no source exists. - The tool is available at the Chrome Web Store listing.

The details: - The extension labels some checks as “consensus” when practitioners broadly agree on the rule but no search engine has confirmed it. - Founder and Lead SEO Strategist Nnabuike Precious said much of the industry repeats claims as fact even when Google has not confirmed them. - Precious said the point is not that unverified claims are wrong, but that they are unverified and should be labeled that way. - CiteCheck handles llms.txt by showing whether a site has the file, but it does not score the file. - Precious said scoring llms.txt would imply certainty about whether search engines or AI companies read it, which has not been confirmed. - The extension also checks robots.txt handling for AI crawlers. - CiteCheck includes a page-level entity check that compares how a page identifies the business behind it with how the rest of the site describes that business. - The tool surfaces inconsistent names, mismatched addresses and conflicting founding dates. - Mackyclyde SEO says those inconsistencies matter because AI systems assemble recommendations by reading across sources and can skip businesses whose own documents conflict. - CiteCheck requests only permission to read the active tab. - The extension uses no host permissions. - CiteCheck sends no data to a server. - Results can be exported as markdown or JSON.

Between the lines: - The release challenges a basic assumption in SEO marketing: that all commonly cited best practices deserve the same level of trust. - By separating documented rules from consensus and guesswork, Mackyclyde SEO is positioning itself as a more skeptical voice in an industry that often relies on inherited advice. - The privacy-first design also signals a product aimed at hands-on site owners, not just agencies. - Precious framed the free release as partly strategic, since users can spot problems before talking to any agency, including Mackyclyde SEO.

What's next: - Mackyclyde SEO wants site owners to run CiteCheck on their own sites before hiring outside help. - The company expects the tool to be used as a first-pass audit for SEO and AI-search readiness. - If adoption grows, the extension could become a reference point for how the industry separates documented guidance from unsupported convention.

The bottom line: - CiteCheck is less a conventional SEO checker than a truth-test for SEO advice, with every rule labeled by how much evidence backs it.
