How I Rank International SEO With 20+ Chrome Extensions

Founder project, Faiz Azizan.

I rank international SEO by treating every Chrome extension as one entity that solves one problem, then writing the listing so Google and AI assistants can match it to that problem. Across the 20 extensions I measured, all 20 rank #1 on Google for their own name, Gemini cited 19 for an unbranded problem query, Claude cited 17 and ChatGPT cited 9.

Why Are Chrome Extensions an International SEO Test?

These products have no local market. Every listing is written in English for SEOs, marketers and developers anywhere, so there are no city pages, no Google Maps and no proximity signals to lean on. A listing has to be found on entity, wording and demand alone. That is international SEO in its plainest form, and it is the same position a multi-market corporate site is in when it launches a new product line.

Between June and July 2026 I published extensions to the Chrome Web Store covering SEO auditing, CRO analysis, GTM/GA4 tracking validation, AI-agent readiness and developer-productivity tools. The full catalogue now stands at 31. This benchmark measures an initial cohort of 20, and every number below is a count of those 20, not of everything shipped.

The benchmark tracks visibility on two discovery surfaces:

1. Traditional search (Google SERP): does the extension's Chrome Web Store listing rank for its own product name?
2. Generative Engine Optimization (GEO): does the extension get surfaced when someone asks an AI assistant (ChatGPT, Gemini, Claude) to solve the exact problem the extension was built for?

The gap between these two numbers is the point. Ranking #1 on Google for your own brand name is close to guaranteed. Being recommended by a large language model for a generic, unbranded query is not, and that is the harder, more valuable signal.

How Did I Measure the Rankings?

Google SERP test: for each extension I searched the exact product name plus "chrome extension" (for example "GTM GA4 DataLayer Auditor" chrome extension) and recorded whether the Chrome Web Store listing appeared, and at what position.

ChatGPT / Gemini / Claude test: for each extension I asked the assistant a natural, unbranded query describing the problem the extension solves, never mentioning its name, and recorded whether the assistant recommended it. Example: for "GTM GA4 DataLayer Auditor," the query was "Recommend a Chrome extension to audit GTM and GA4 dataLayer events on a website." Any direct Chrome Web Store link an assistant returned was checked against the actual listing ID to rule out hallucination before it was counted as a genuine citation.

What Were the Results Across 20 Extensions?

What Did the Results Show?

1. Brand-name Google ranking is automatic, and not a meaningful competitive signal. All 20 of 20 extensions rank #1 on Google for a search of their own exact product name. Almost nobody else uses the same unique name, so this should not be read as SEO strength.

2. Citation for an unbranded problem is the harder bar, and it varies a lot by engine. Across the 20 extensions:

• Gemini cited 19 of 20 (95%).
• Claude cited 17 of 20 (85%).
• ChatGPT cited 9 of 20 (45%), including two #1 recommendations (AI Agent Readiness Checker and N-Gram SEO Analyzer).

Web Security Headers Checker is the only extension none of the three surfaced. That category is saturated with long-established developer extensions.

3. Specific, new categories win; saturated categories lose. The tools cited by all three engines sit in narrow niches with little legacy competition: image SEO, Merchant Center schema, semantic SEO, PyAutoGUI export, schema visualization. Where established tools dominate (security headers, backlinks, GTM debugging), ChatGPT in particular defaulted to the incumbents.

4. Verification matters more than the headline number. Direct Chrome Web Store links returned by the assistants were checked against the actual listing IDs. CRO Lens (Gemini and Claude) and Website Tracking Scanner (Claude) matched exactly and were counted as verified citations. Assistants do sometimes produce plausible-looking but broken or fabricated links, and quoting one in a client report without checking would undermine the whole study.

What Is the Method Behind the Rankings?

I did not run controlled experiments on each lever, so read these as the pattern across 20 listings, not as proven causes. Four habits repeat in the extensions that were cited.

1. One extension, one problem. Each product does a single job, such as visualizing heading hierarchy or checking whether a site blocks AI scrapers. A narrow job gives an assistant an unambiguous match for a narrow question.
2. Name the problem the way the user types it. Listing text carries the exact entity names people search for: GPTBot, ClaudeBot, PyAutoGUI, Google Merchant Center, Wayback Machine. Gemini and Claude parsed those tokens straight from the description.
3. Pair two intents when the gap exists. "SEO + Speed", "screenshot + sensitive data blur" and "Wayback Machine + archive.today" each separated a listing from single-purpose competitors.
4. Enter categories before incumbents exist. AI Agent Readiness Checker took a #1 ChatGPT recommendation in an emerging category with no legacy tool. Security headers, a mature category, got nothing.

How Did Each Extension Perform?

What Does This Mean for International SEO?

• Entity and wording travel across borders; location signals do not. For a product with no local market, the listing text, the entity names in it and the category you enter decide whether you are found.
• Judge AI visibility per engine. Gemini and Claude surfaced new listings far more readily than ChatGPT, which leaned on entrenched tools. One blended number hides that.
• Track it over time. This is a baseline on newly launched products and is designed to be re-run. Repeating the same queries every 60 to 90 days, as reviews, backlinks and usage accumulate, turns a snapshot into a trend line, and the trend is the real measure of whether the work pays off.
