There was a great thread on here recently about improving your Chrome store ranking. Based on it I updated my listing and resubmitted. And then wondered whether my changes had had any effect!
Since you can't improve what you can't measure I put together a little snippet of JS that you can run from the store search/listing page to tell you where you rank for a given search query. See below for code you can copy into the Chrome dev tools and save as a snippet. Replace your extension id for mine, enter your search string on the page and run the snippet to see where you rank!
let appId = "fialfmcgpibjgdoeodaondepigiiddio"
let query = $("#searchbox-input").value;
let appRow = document.querySelectorAll(`div[role="grid"] a[href*="${appId}"]`)[0];
if (!appRow)
console.log(`App not present for "${query}"`);
else {
if (appRow.getAttribute('index'))
console.log(`App is at index ${appRow.getAttribute('index')} for "${query}"`);
else
console.log(`App is at index ${appRow.getAttribute('tabindex')} for "${query}"`);
}
Disclaimer - this was reverse engineered from the web store page and works for me today, there's no guarantee it will work in the future, or work for anyone else (altho I hope it does!)
