Did you even noticed, that when you search for extension in the Chrome Web Store, the auto-complete always shows the same extensions?
OK not always the same, but let's say that some are more present, no matter what you search.
The thing is, search results are displayed already after entering a single character...
So... I've wrote a short script that "triggers" auto-complete suggestions box for each letter of alphabet and then I've put the results into a table to see which extensions have "best SEO" :).
This is the sheet - it has two sheets, first shows the aggregated data, second is the raw data:
Any thoughts? :)
