Funny how only 10-30 pages of search results are considered low demand, especially since buyers rarely search beyond the first few pages. For almost all of these searches there is more than one image per search. Now if this is daily searches, that isn't bad, if it is over a month, you can see why sales are so low.
also is "1999 2000 2021 calendar" really the #1 search term? over what time frame, a few days before new years? I would expect something one word like "nature" or "diversity" or "environment" or "woman"? Back when SS published the top search terms (from everyone I presume, not just buyers) it seemed like more than 1/2 the top 100 were one word searches, with the usual Christmas, background, and business you would expect but also a lot of porny searches too.
I do miss the tool SS had for a bit that showed searches over a calendar year, that was pretty interesting - especially comparing similar terms.
If I was still selling on SS I would consider adding colors to all my background keywords and also "big" to my question marks.
