Increase in Google traffic X3

Hello everyone, Im wondering if anyone else has had this happen recently,

Organic Traffic from Google is usually between 70-100 per day..... all of a sudden on July 9th this tripled, and I have no idea why.....

Traffic has increased and keywords have also..... Keywords were approx 500-600 per week, now they are 1000-1400.

Keywords are all mainly related to my niche as well..... this has happened out of the blue, and Im wondering if anyone has any suggestions as to why the sudden increase when Ive changed nothing on my site.....

Heres a couple of Google Analytics screen shots:

Any Suggestions?

I have seen a good increase in daily traffic from google. In my case it's not tripled but it's still very significant!

very nice glad to hea its working well for you

Congratulations.
