Drop off in clicks after a few days?

I run a large ecommerce site selling stationary. We sell around 15,000 different products however there is generally quite a lot of competition with most of them.

Now looking through the stats after almost a month of submitting the listing, I note after logging into google base that the number of clicks through in the first few days was around 50-60/day which gradually dropped over the course of the week and has now evened out at around 15-25.

Any idea why this may be? It's free targeted traffic so I'm not complaining or anything, but I am curious as to why this has happened. Do fresh listings get higher priority for example?

 

you have to seo your feeds and have to add more and more details of your product's feeds in base !!!

 

There are about 197 factors affecting foogle SERP, so you should check :

1. Site relevancy (your actual PR has lowered)
2. Incoming links.
3. Penalized ?

So I recommend to check this SEO Check List


Hope it help
