A link from another website to your website is called a backlink. The more quality backlinks you have the better your website will perform in the search engines. One quality backlink is more powerful than 10 or 20 random links. Quality of the link defines your webpage importance. Low quality backlinks highly impact your website rankings. The below are the characteristics of a quality backlink.
Keyword Phrase in Anchor text
For better results, a backlink with your keyword in the anchor text increases your link influence. Let’s say, you have a backlink to a product page that sells “Blue Nike Sneakers”, your link influence score increases if the backlink has anchor text “Blue Nike Sneakers”.
A backlink from related page increases importance of your webpage. Non-related links has no influence whatsoever. A link from food article page to your page that sells Nike sneakers is considered as non-related link and does not increase your website ranking. But if you have link from a sports store or an article based on the product you are selling, it performs well in search engines. Google rely on many factors to filter search results and incoming link relevancy is one of the factors that affects your SERP position.
Link from an Authority Site
Links from high Google PageRank sites are worth more, a lot more, than links from other sites. A link from a trusted site tells the search engines that the sites linked to can also be trusted. It’s a vote of confidence from a credible source. Links from .gov, and .edu sites are also reported as having more weight than standard links. It is more difficult to get these links adding to their perceived quality. Use this tool to check page rank (opens in new window).
The Link is at Top of the Page
Links from the top of the page (except for the header), are said to have more weight than links at the bottom of pages. It’s the same with keyword phrases. A keyword phrase in the heading is worth more than in the body text. It is worth a lot if your link appears in the first two paragraphs on that page that is linked to you.
Not a Reciprocal Link
Google’s algorithm looks for link exchanges between sites and rates these links lower than straight one-way links. If possible, look for one way links by creating compelling content that will encourage people to link to your pages.
Link is not in an Advertising Zone
Linking should be a natural part of the body copy. Search engines may not consider your link influence if it appears on certain parts of the page that are traditionally sold for advertising. These tend to be the margins, header and footer areas of the page.
Link is not a No-Follow
The no-follow tag is way of telling search engines that although I am linking to this other page, I do not vouch for the page’s integrity. In short, the no-follow tag tells the search engines to ignore the link. Obviously it is not worth to have links to your web pages that has no-follow tags but Google still consider no-follow backlinks to rank websites.
Too Many Links on the Page
If a webpage has your link but also has a few hundred other links, your link influence score would be lesser. The page’s SEO power is being distributed over all the other links on the page. Google’s guidelines recommend no more than 100 links per page. The page that links to your webpage should have lesser links.
