There's two goals for link building search engine optimization. They are to improve traffic to the site and to enhance the site’s placement in the search engines. A site’s placement is going to increase with the amount of backlinks which it has. That said, in this instance the quality of the links is much more significant than quantity. Acquiring dozens of low quality backlinks is nowhere near as valuable as obtaining two good quality links. Search engines like Google and others will provide a website a high rank if it has a number of quality backlinks because they consider the site as important. There are several things to ascertain the value of a backlink and they're listed below.
1) Anchor text. Basically, anchor text is the text which is visible to someone looking at the link. For example, simply clicking a link to a car insurance company like Progressive might take you to progressive.com, but the text you see and click on may read "auto insurance". Anchor text that is descriptive about the website or web page offers greater value than a simple URL link when it comes to link building SEO.
2) Page authority. Positioning your links on websites or web pages which have increased worth in the eyes of the search engines is critical. Links from .gov sites are typically a lot more advantageous than acquiring links from a .com site which has not legitimate authority.
3) Volume of links on the web page. You'll get more value for your link if you are the only link on the webpage where you place the link. You will see it in mathematical terms. On a page which has a value of 100 if you are the only link you will obtain 100% of the value but if your link is there with 20 other links then you'll only get 5% value.
4) Domain age. The age of the domain where the backlink is placed has some value on the link. This is because older and more established sites will be more trustworthy to Google and other search engines.
5) Relevancy. If the web page the backlink is originating from is centered on scrapbooking and the backlink leads to another site about scrapbooking, the backlink has far more value than if it leads to a website about exotic cars. Google weighs the value of all incoming links to a website, link building SEO is about building links that work together in concert around a common relevant theme.
While they're some of the most critical aspects to link building SEO there may be other smaller factors that you can consider.
