External links to the site: what are they?

Over the past year has seen many changes in SEO. Gone are the days when everything was decided by millions of links from directories. Link building has always been not an easy task, at least building really high quality links. Therefore, people are expected to start taking a new approach to link building if they hope to succeed.
Actually, this article contains some tips on how best to build links:

Quality (not quantity) decides.
Google has already learned to distinguish «good» links from «bad» links these days, so if you want to be in the Big G's favorites, you need to start building good links. Of course, even now it is important to have links of varying quality, and you will have some links better and others worse, but you need to categorically give up on «spammy» links.

A lot of people think that posting blog posts is a great link building technique. It really is, but if you start posting a bunch of posts on small blogs or blogs with no authority, Google will quickly figure out your tactics and you won't see the results you want in search engine rankings.
The same thing happens with link placement in directories. If you are posting links in directories, you need to make sure that these directories are of high quality and not just a place to leave a link for free.
