For my website it has never carried out SEO changes or any activities related to same. I started working on it from this month March 10th and every form of changes i.e. Title tags changes, Onpage changes, Content Modification as per keywords were completed on 21st Mar 2014. One thing is we were ranking well between March 10th to 20th on Alexa Global Rankings when work was on the website. Once the URL was restructured as per keywords, the traffic started dropping till date on Global Rankings. But regional Traffic has improved after certain drops.
So I want to know the reason behind the drop?
Is it due to the changes in URL structure from what it was before or anything else?
If its due to URL changes, when does Google starts giving value to those urls.
Note: Main Domain has not been changed and its up since 2001 without any changes done to it.
