I found few nice tips on building backlinks the right way and their value, a lot of us might already know how to do that but there are still some of us who will extract few new ideas, so I decided to share those tips here;
How does Google's rank websites? Well, if I were an oversimplifying kind of person, I would tell you the following:
When someone does a search on Google, the first thing Google does is locate every site whose meta page title contains the words in that search. It then looks at how many trustworthy (high quality) links each web page in that result set has and puts the ones with the most trustworthy links on the first page and the ones with the least trustworthy links at the very end.
So once you've got the right page title, it's all about links.
It amazes me how much I still hear that SEO is about the things that are on your website. In fact, the main service most so-called SEO companies sell is one where they work on your website to cause it to attract search engine traffic. This boggles my mind because, other than the meta page title, what's on your website barely even matters to Google! It's all about links.
Links are to Google what grades and SAT scores are to a college admission officer. Does the admission officer care what you look like on your interview? Sure. But he wouldn't have invited you for the interview in the first place if you didn't have high enough grades and SAT scores. Similarly, does Google care about how user-friendly your website is, what's written on it, and how fast it loads? Absolutely. But they won't even look at it if you don't have the right quality and quantity of links.
That being said, if you have great links but maintain a poorly coded, slow website with nonsense copy written on it, you won't have much luck ranking on Google. Just as you wouldn't have much luck getting into college if you have perfect grades and SATs but show up late to your interview wearing sloppy clothes and making wisecracks at your admission officer.
The point I'm trying to make is this: Links matter far more than any other factor. And if you get the link component and the meta page title component right, you've got 85% of the job done right there.
