Directory Submission in SEO?
What is the use of Directory Submission in terms of SEO?
Directory submission is just waste of time.
Google is too clever to consider such a stupid backlink. Just one single update from Google pointing that backlinks from directory submission sites need to disallowed will affect your website & strike it down.
So, I would suggest you not to waste time on it.
There are lots of popular business directories where you can create profile of your company and share link of your website. This will be helpful not only from the SEO perspective but also for bringing referral traffic to your website. Point of caution: You should select business directories of the locality where you business provide services.
I used to do directories, when I started my career but now this tactics is no more effective to get your website ranking. But if you really want to invest some of your time then you may submissions on only very high domain authority website. Also you may check its trust flow and spam score first before doing any submissions...
