Hello BHW members! I'm looking for a way to index a pdf. I saw a lot of "Game Generators" pdf. classified on the first google page indexed in minutes. Does anyone have any idea how to do this?

Hello guys! Does anyone know about how can index my backlinks? I m using GSA indexer, indexification, and other tools but my backlinks are not indexed? which tools should I use to index my backlinks quickly? which way to index my backlinks fast? if anyone knows about it so please guide me...

Hi, I used to use SEO indexing services in the past and now that I'm back doing IM again I find that my ranks go up even though I'm not using indexing services. Is indexing a waste of time? It appears Google gets around to finding everything in a week or so anyhow. I'm considering GSA SEO...

I had tried many backlinks index tools for a long time, But I haven't found the one works good. And I think you experts must have some great suggestions on index tool for me. Also, I heard from someone that "indexification" seems to be effective, what do you think? Many thanks!
