There are numerous SEO myths about using free backlinks to position your site at the top of Google. Backlinks are merely one way links to your site. Using any free backlink generator
will not automatically rank your site number one on the internet any more than other methods will. The fact is you should devote some work and employ a number of various ways.
Some tasks are necessary around the page- ie place your main keywords in the html title, as well as in the H1 title and a few times on the page. Also if it's a blog have a category name which has keywords, and many posts making use of it in many different ways.
The greatest part of SEO is done off-page. Your should gain quality links along with your keywords as anchor test ie the written text which is clicked. I suggest enjoying a combination of links - don't merely make a choice without the nofollow tag or perhaps choose ones from high PR sites. The entire point would be to help make your links look as natural as you possibly can so that you won't be penalized in any way. It's also advisable to not just have links going to your webpage - some is going deeper to your site or blog (link to individual posts or pages).
So you should play one with the backlinks generator scripts to create your a number of your links and compliment it'll other methods including forum posting, article creation, weebly sites, blogger blogs etc. It'll all help.
