Now today I am going to discuss about the importance of link building in SEO. But before we proceed further we need to know what this link building is? Link Building is a process to create back links to your website. Link building process help to create link popularity of your website. Back link is an anchor tag of another good ranking website points back to your website.
There are several things that made link building is an important and tough job for SEO of a website.
Impact on Search Engines: When you typed a “Phrase” or “Keyword” in a search engine like Google, Google will search in their database for that particular keyword and looking for the all websites in the world for that keyword or similar to that to find out best result for your query. In this long process search engines uses a very complicated algorithm to find out the result and look for the keyword or phrase on various websites which is thinks that this keyword is relevant for a particular link. If your website URL is on various well ranked website and they think that your link is relevant to point you back then automatically chance of your website’s rank on SERPs increases.
Global popularity: The more popular a site is, the more important the links from the site is. A website like Wikipedia has literally 1000’s of diverse websites linking to it, which means it’s probably a popular and important website. To earn trust and authority with the engines, you will need the help of other link partners.
Topic specific popularity: This means links from websites of your niche is matter more than links from general or websites which is not in your niche. For example, if your website sells dog houses, earning links from the society of dog breeders matters much more than earning links from a roller skating website.
Trustrank: It is a technique to separate useful webpages from spam. Some estimates say as much as 60% of web pages are spam. In order to weed out this irrelevant content, search engines use systems for measuring trust, many of which are based on the link graph. Earning links from highly trusted domains can result in a significant boost to this scoring metric. Universities, government websites and non-profit organizations represent examples of high-trust domains.
Link Neighborhood: Spam links often go both ways. A website that links to spam is likely spam itself, and in turn often has many spam sites linking back to it. By looking at the totality of these links in aggregate, search engines can understand the “link neighborhood” your website exists in. Thus, it’s wise to choose those sites you link to carefully and be equally selective with the sites you attempt to earn links from.
