There are many ways to build quality backlinks and one of the most preferred way to many is trough article submission to article directories. There are hundreds of article directories and some gives dofollow backlinks with anchored keyword in author section to the writers. Relevant contents and dofollow keyword anchored backlinks is what we all need to increase SERP ranking in search engines. But, there are one similar mistake done by many article writers and submission service providers.
It is true that if you submit articles on 100 different article directories with anchored keyword backlink on author section, you will gain 100 backlinks from all different unique domain. But, what they usually do is submitting the same content on 100 article directories and expecting to get 100 backlinks from this submission. Remember, Google and other search engines filters copied contents. The first article directory that gets crawled and indexed from 100 directories that we have submitted with same content, will get indexed. The balance 99 article directories will get flushed on duplicate content issues.
So, it is a real waste of time to submit on multiple article directories with same article. If you can take 2 hours to write one quality article, then you can spend more time re-writing the same article again and again. If you want to submit to 100 article directories, then, re-write this article 100 times before submission. Always make sure to check Copyspace for any copied issues on any of your articles. Copying articles can get our site penalized from search engine too. We are finding ways to improve our site ranking not the other way around.
