I have some questions that came with time while I was trying to SEO. 1. Buying blogspots, some people offer to post your link with within an article, some blog are just made with articles that only include links to affiliate or adsense websites, I under stand one should also look for DA, TF and all that. but what about common sense? does Google can't really see it? 2. When you buy tier 2 links (links that point to a site that point to your money site), some offer links like accounts on forums or educational blogs with link in profile. Some do facebook and twitter, etc.. with many, few or even just one link, with very little content or not at all. Does it really good? again, common sense, I guess google bots can see it.. 3. I don't like to use any google services, why to give someone else information about my business? if site is good it will rank, but if a website uses the google webmaster tools and the code they ask to insert in your site files, does it help to rank better?
