Now, as the dust settles from the last days and my panic is under control :->, I thought I share some ideas here.
1. Nature of site: eCommerce
2. Type of link building: across the board
specialties: our sellers get subdomains, minimal link buying, majorly press, partners, etc.
3. Pages on domain: somewhere around 3 Mio. pages,
majorly product details and listing pages of products
History: Until Tuesday we ramped in around 200k Uniques a day - very strong long tail traffic, 65% of the landing pages are the product details.
What happened: First the site lost one PR point from 6 to 5 in the last update. Traffic went up, so I did not care at all, but maybe it completes the picture.
Tuesday, April 27th: solid and good traffic, but slightly lower than last week.
Wednesday, April 28th: first noticeable drop of around 10%
Thursday: 25% loss of traffic to Tuesday
Yesterday: 27% loss of traffic to Tuesday
Think this is the current status: Lost around 25% of power/traffic somehow.
Hard to say really, but here are some cents for the collective thought pool:
a) Keywords I monitor are still where they were, but these (around 20) keywords are not really LONG TAIL
b) Some merchants selling strong in the past weeks dropped out of the sky and vanished from our top sellers list: that could be the reason.
I looked here in this senseless long thread :-) and found the following quotes spark a clue:
I think the loss of long tail is more to do with Google's incredible improvements in Adwords relevance matching. - internetheaven
Well, my loss in traffic is majorly long tail - so that area fits at least.
Long tail traffic in most cases relies on internal link juice, this is how it works. - SEOPTI
There is so much insight in that one sentence, I love it!
And I can relate to it in my case:
The few top sellers vanishing from the list are providing thousands of niche products for very specific purposes. They lost the traffic and that whole picture falls in to place:
If this is the Caffeine update, IMHO the following happens while we type:
Deep content is gathered from domains not crawled so deep before. The amount of pages with long tail keywords doubles, tripples or just magnifolds and changes the game as a whole.
If internal link juice is now weaker or stronger: Link building has now a different meaning.
Link juice must be handled under a differen perspective.
Even if we can build up 1,000 named backlinks to a page, it looses its power on 3 Mio. children quite quickly.
If there are major authority sites unlocked by Caffeine with "before 100,000 pages" and after "10,000,000 deep pages" we have now
9,900,000 new enemies in the long tail....
That would explain a lot to me and I wonder what you think?
