That's essential info!
It emans that even though I have bene posting a lot + content is posted on several blogs, posts still appear on top of search results.
This means that the blog IS being indexed.
The drop in traffic probably means that results simply don't receive the initial ranking boost related with the freshness of the post.
The 10 new posts all optimized for specific high traffic keyphrases all rank in the top 3 for the last 24 hours results and around top 10 for the past week results.
On top of that, even though the post has been made to many different blogs, it is still the main breakup blog that gets the ranking for that specific keyword.
I already discussed why that specific blog might be privileged by search engines but might come back to that in another post and try to understand the exact dynamics.
Over a week, many of the different blogs have seen a sudden surge in traffic for 24 hours and then quasy disappear...
Some analysis of why this happens in a future post
