An Etsy tool site with 12k followers added an extension and got 500 users in a month: legacy brands don't work well in the Chrome Store

RankHero is an Etsy SEO tool site that has been around for years, formerly called EtsyCheck. This September it launched a Chrome extension that shows keyword search volume and estimated sales directly on Etsy pages. Users went from 2 to about 500 in a month. It looks like growth, but it's mostly existing users moving over. In the same month, a free extension built by a Pakistani SEO trainer reached 7,000. The category is already crowded. What's worth watching is how tools that already have a website use an extension to keep people.

A video with 42 views

On Nov 3 2026, the TikTok account @rankhero.com posted: "RankHero Chrome Extension is now available." The account has 12,341 followers and 58 videos, its bio reads "Formerly EtsyCheck," and its most popular video is an Etsy keyword tutorial from Feb 7 with 228k views. The post announcing the extension had 42 views by Nov 6 (TikTok, 11-06).

Over the same period, the extension's user count on the Chrome Web Store moved like this:

400 users with only 3 ratings. There's no sign of rating manipulation, and no paid acquisition found.

What it is

Once installed, typing in Etsy's search bar shows two numbers next to each suggestion: Google monthly search volume and how many Etsy listings are competing for the term. This is free on all plans. Search results and listing pages also get an estimate of "total sales and total revenue," and a small panel shows views, favorites, price, and how long the listing has been up.

The store page says it works "without covering the shopping experience with a bulky sidebar." That's the only difference it openly states from its older competitors.

The paywall is in the quota: data you already have is free to view, but each live fetch or refresh costs 1 credit, even if no estimate comes back. The free plan gets 5 per day, Side Hustle 25, Business 100, and Enterprise 300, resetting daily at midnight US Central time (rankhero.com/chrome-extension). The extension requires a RankHero account. Website plans cost about $5.99/month and $9.99/month on annual billing, cheaper than EverBee and Alura.

Where the 500 users came from

Mostly existing website users. The website has a full page on the extension, every pricing tier lists its extension quota, and the first step after installing is "Connect RankHero." The site claims it has served 500k+ sellers in 127 countries (unverified). A site that size only moved a few hundred people over in the first month after adding the extension, and that group drove most of the growth.

Its own social accounts aren't pulling much. Apart from the TikTok with 42 views, the official subreddit r/RankHero posted an extension introduction, and in the last 60 days only 0 posts on X mentioned RankHero.

Word of mouth is for the website, not the extension. In r/EtsySellers and r/EtsyCommunity, people recommend its tag generator and shop analyzer. Roundups like outfy and ehunt's "Best Etsy SEO tools 2026" list it, and the site has an "EverBee vs RankHero" comparison page. All of this drives traffic to the website. The extension is a side benefit.

Why the extension comes so late: in 24 May 2025, EtsyCheck announced a rename, and the reason was blunt: "Etsy is a registered trademark and can't be used in the name long-term," and it was easy to mistake for an official Etsy product. The overhaul happened in two steps, with the full site and backend rebuilt in February 2026. The extension is the final piece of that round, catching up with something competitors already had.

Who it's competing with

"See keyword volume and sales directly on Etsy pages" was already available five years ago. RankHero is the 10th-plus to build it.

SBMM is worth a closer look. It launched two weeks after RankHero and has more than ten times the users. Its creator, Moqeem Ahmed, is based in Pakistan, started doing SEO 2011 years ago, and lists "Trained 45000+ Students Globally" on LinkedIn. The extension covers more than Etsy: it also adds backlink and domain authority data to Google search results, and it's completely free with no signup required. He promotes it through videos on his Facebook page, titled "Etsy Research Tools For Free For limit Seats Yet." So SBMM didn't come out of nowhere either. It has a ready-made audience of people who are used to "install a free extension" and don't need to create an account first.

What to learn from it

• An extension is a retention hook for the website, not an acquisition channel. RankHero's design is clean: the most-used data (keyword volume) is always free, so people keep it open every day. Sales estimates are metered per fetch, and the quota is tied to the website plan, so heavy users are pushed to upgrade. A tool site that already has paying users can build an extension like this cheaply, and it keeps people in their daily workflow. Just don't expect it to bring in new users.
• Requiring signup before install cuts growth off. RankHero requires an account first, while SBMM works right after install. On the Chrome Web Store, the lower-friction option tends to grow faster (inferred).
• Don't put a platform trademark in the name. EtsyCheck still had to rename after years of use, and the new social accounts have to start from zero.

If it were you

In short: Don't build an Etsy seller extension. The space has a dozen-plus competitors, a top player with 200k users, and even an established site with a reputation of hundreds of thousands of users only got 500.

Who it fits: People who already have a tool site with paying users. Copy RankHero's approach and add an extension for retention and upsells. If you pick a seller platform other than Etsy that isn't yet crowded with extensions, there may be room, but ListingView already covers both Etsy and TikTok Shop, so check the store first.

Who it doesn't fit: Anyone starting from scratch who wants to build a business on an Etsy extension. The features are already well covered. What's left to compete on is free access and store ranking, and SBMM and EHunt already own the free route.

How to do it: If you have a website, give away a number people check every day for free, and charge per use for a second number, with quotas tied to your website plan. Show the data on the first screen after install, and push signup later.

How to get users: The extension won't bring in users by itself. You still need the channel that brings people to your website. SBMM relies on its trainer's students and Facebook groups, and RankHero relies on TikTok tutorials and Reddit word of mouth. If you don't have that channel, don't build this.

Do the math: ① By 2027 January, RankHero's extension had 10k users. So the old brand's traffic does work, just slowly. ② EverBee and eRank extension users have started to drop, which means this slot is changing hands, and the newcomers still have a shot. ③ Etsy put search volume and competition counts right into the seller dashboard, so the whole category could shrink.
