The links a blog receives from other sites, can greatly influence the positioning of pages in search engine results in the search engine Google.
They are considered important by Google and also in website optimization because in most cases they are created by webmasters (or bloggers) who create links in their websites or blogs pointing to your blog by pure will, without having been manipulated.
The links in this case are considered votes of credibility, where the site is the link, gives the blog that receives a vote of confidence.
The more votes a blog receives, the more important it is to the Google. This means that the greater the chances of the pages of the blog that gets the link appear in the first positions of search results.
Of course, every link and the link will always be welcome, but there are some criteria that are taken into account by Google in relation to external links that can influence the value that will be given to the receiving site.
Page that receives the link
One thing we must realize is that the value added to the vote is given only to the page that receives and not the blog as a whole. This means that if one of the pages of a site received a link, this page will be privileged.
Keywords
As the internal links, and more important optimized sites, the words contained in the link anchors are taken into account to determine the words which the site that receives the link should be well positioned.
Importance of the page where the link is
The more important part of the page that the link is located, the more value you can pass to this link the blog receives.
So links that start from new sites usually do not help to improve the importance of the site that receives it does not matter to Google.
Niche site that shows the link
The link will have much more value if the issue addressed in the site that gives the link is relevant to the site that receives it.
Receive a link to a site that talks about cars will not help much in the position if your site talks about paintings.
How to get links
My experience with the creation of websites and blogs taught me that there is no easy way to get links that actually add value to a blog.
I found that the best way to get links is really worthy, creating quality content that other webmasters find it interesting enough to point a link to. Another good way of creating links is submitting free articles to free articles directories. If these articles are interesting enough webmasters will take this content to their websites and usually retaining the author resource box which contains your link to your website or blog.
Also if you you are new I recommend disclosing your blog in directories of sites and networks such as bookmarking Via6 is FCC.
IMPORTANT
I recommend you avoid participating in trading schemes of links (also called reciprocal links) because they are considered technical Black Hat Seo and your blog may end up being penalized by Google.
