To be honest...I think this is a secondary concern. Your primary concern should be assigning the values correctly.

For example: If i select work from home, it returns Intuit, if I click apply, it takes me to their ATS...This is good, but it seems they are not offering work from home, so this result is false.

The reason why Key Values is enjoying some success is due to marketing. Right niche, good promotion, good design, good sales. (but even then, not that many companies have signed up. why not? They are probably aware of it.)

This format might work if you go after a different segment of the software industry (maybe?). I am currently doing something similiar in a unrelated industry, it helps if you can talk the lingo, know some people etc.

P.s Unlesss the companies have already paid to be listed? Then, well done.
