By the way, something I did not mention yet is that when I check overall stats for all sites, these new blog posts of this last week account to 5-10% of the entries into the site.
What is surprising is that this traffic does not show up as an overall increase in traffic.
This is a strange phenomenon that I observed before in various situation and have no explanation for:
A boost in traffic in one area is VERY frequently accompanied by a decrease of traffic in another aspect of the site or traffic to a specific page.
I am not 100% sure if this is true or it is only my imagination but it is something I seem to have observed frequently.
Anyway - 5-10% IS a result - something to remember when taking future steps
