My website has lost ranking but only for 2 (basic) keywords.
Does anyone help me why is this happened?
What can I do now?
Usually two reasons:
- One or more sites (with a decent page rank) have removed links to your sites
- You've been penalised for "Black Hat" activities. Search engines don't like dubious practices to build up page rank.
Also note the page rank changes periodically. It might reflect an action from 2 or 3 months ago.
Do link building for these two keywords. Now a days relevant link building is important.
It could be for a million different reasons. The most likely is because the Internet is constantly changing. Google regularly changes its algorithm, people regularly set up new sites that may be relevant to your website, and so on.
The reality is that you could be doing the right things and still not make any gains.
