Few questions regarding indexing and seo

Hi there.

I have a new month old website (wordpress based) on a keyword with 40k local hits p/month.
My only competitors are wikipedia and some website that doesnt contain the keyword in its domain name, neighter in its anchor backlinks but just has some small worthless content about it.

So this shouldn't be very hard to rank for right? Well i am having a hard time atm.

I don't want to screw up this time as 2 of my previous websites got sandboxed.
I use ScrapeBox to scrape niche blogs, after that i remove all URL's with lower PR then 3. Everything that is left (so all +PR3 blogarticles related to my niche) i go to, read the content, and place a legit manual comment on it. I have been doing that for approx 14 days now around 5-10 comments a day, i save the url's and ping them afterwards.

The problem is that not even 1 of those comments has been indexed as a backlink sofar when i check. Am i doing something wrong? I do check the comments 1-2 days later and most of them get approved and published by the blogowner.

I am currently like result nr 7 for my keyword, only top 2 results are competition as i said, rest isn't even niche related or keyworded for it.


ps. extra question?
I have a Facebook like box on the website with only 2 likes/followers. If i buy lets say 1000 likes to it trough fiverr, will that have any weigh on my SEO?


thanks in advance
