Welcome to the Q&A Forum

Hi,

Thanks for your answer.

The domain is not new. (2 years). Not too much link building. Frech content every day.

For example: we have a page which was first on Google research with one keyword for at least 2 years. it brings us a lot of traffic.

Suddenly the page goes down to position 49 for few days and go back to the 1st position. It happen few time since Pinguin.

Right now, we are penalized again and it lasts since 10 days now.

Our webiste is made of 2 different parts hosted in 2 different directory on the same domain:

1. The website itself, which can be seen as a catalog.

2. A blog on WP.

Sometimes we lose 50% of our traffic and 5 to 10 days later the traffic goes up again.

When looking at position in Google it appears that when losses of traffic happen, the Google positions of pages from the website become bad. The blog pages themselves keep their good position. Suddenly after few days we find our previous good postioning and we have a good traffic again.

Here at the questions we have:

1. Why do we have variation on our Google positioning? Which parameters can influence? Bounce rate? Speed?

3. Why only the website is penalized and never the WP blog whereas they are on same domain?

If someone has experienced it before or has a idea, your expertise is welcome...

Thanks.
