Link building used to be the main factor in SEO; the more links you build, the more chances your SERP will increase and the higher quality links you obtain, the more competitive your link building will be. But due to the unnatural linking and violation to search engine guidelines of many SEOs, Google launched their spam algorithms to filter the websites that are good ones and show up in SERP to give useful information to searchers.
As a result of Google's action, the world of SEO as we know it is dead or no longer effective. SEO has also become more complicated when the common types of link acquisition has been devalued by Google. Here are the common types of low quality links that we can easily get through the following:
· Web Directories Submission - This was abused by using exhaustive keywords and by using deep pages of a website to be submitted to web directories.
· Article Marketing - This was abused by using low quality and thin content. Article marketing was purposely used to manipulate links by unnaturally using a targeted keyword as an anchor txt.
· Social Bookmarking - This was abused by using pligg sites. Social bookmarking is still effective but on high quality ones only such as digg, delicious and diigo and if your bookmark goes viral.
In the modern SEO, there are some important factors that you must know before you build links on a website. This will help you obtain high quality and relevant links that your website will benefit from in the long run and these are:
Domain authority – Page Rank is not that only factor that we should look at when linking our website to others. Domain authority is what we should also look at as this will benefit and give our website a strong link value which can also make our website stand out within our industry. Domain authority is rank from 0-100 and the ideal domain author is 70 up to 100. You can use Google chrome extensions to use free SEO tools such as Moz-Rank to help you know what the DA of a website is.
Update frequency - Also, a consistent website update through blog section update of a website determines how often a website is being visited and crawled by spiders. If the website you are planning to link to was last updated in 2011, this could trigger Google to doubt your link building performance as it is considered as unnatural linking in my point of view. Update frequency should be at least 4 times in a month or one blog post update in a week. This should be enough to consider a website as active, properly maintained in a regular basis.
Social media signals - After the roll out of Google algorithms, the value of social signals have become more important. If you are thinking of linking to a website with higher rate of social shares, it is a good idea as this would give you more exposure in other communities within you niche especially if you contributed a content with a link to your site.
Link building for the sake of increasing website links popularity and SEO strategies are not enough. Numbers of links don’t matter in Google’s eye but high qualities are. Therefore, you should be very careful when linking your site to others as this could negatively affect your website.
