SEO sites were blasted by Panda

[MarieHaynes]

Very interesting!

I just spent time looking at my competitors.  Some of the really big guns took a drastic hit as well.

And so much for BlackHats having an upper hand in the game

Or those who believe it's all about backlinks

Maybe any site that smells like it has been touched by an SEO got whacked?

I checked other SEO sites and all that I have checked have been whacked.

[MarieHaynes]

Do you think it could be to do with the backlink pattern?  I mean, if Google can tell that there are an abundance of manufactured links then this would make sense.

[EGOL]

SEO sites get lots of links from SEO blogs.  Very incestuous linking in this niche.

[MarieHaynes]

So perhaps this is Google's way of leveling the playing field and taking away some of the advantage that sites with knowledgeable SEOs have?

[TaitLarson]

Interesting theory!  I just checked us on in trends.  It says we got whacked too.  Still I'm seeing pretty good traffic to our site.  I wonder if those graphs are not as bad as they look.

[EGOL]

I hope not!

[SteveOllington]

WOW!!! That's a hell of a find. It's not like it could be some huge coincidence either, that many sites all hit at exactly the same time. How do we find out more?

[AlanBleiweiss]

yeah unless we can get input from site owners, I am not convinced those are reflective of actual traffic.  Just not sure.

[bemcapaz]

Maybe they changed their metrics? Every site im checking o google trends is showing a huge decline in the number of visitors.

For instance I tryed

Mashable

Techcrunch

Yahoo (not as big as the others but stil...)

They all have a similar graphic as the ones mentioned on this post, so if the visitors are leaving from everywhere , where are they going? To splogs? hehe

[EGOL]

lol.... you are checking all of the low quality sites...     J/K

There are lots of sites that do not show a drop at end of February.

A lot of sites are down at end of April because of college courses ending.

[Gyi]

Perhaps someone from Moz can fill us in...

[TomCritchlow]

Hmm - not sure I'm trusting those graphs. SEOmoz didn't see any change one way or the other with Panda...

[EGOL]

Thanks for looking into this, Tom.

I have been doing a little research myself..... I can find lots of sites that show massive traffic losses on  the dates of panda updates.  However, I am not finding any sites that show substantial traffic gains - at exactly the same time - which is what we would expect to find.  Right?

So, I am now starting to think (like others in this thread) that the data being presented in Google Trends is suspect.

[SteveOllington]

Damn, so Trends should be avoided due to false information for a while or...?

[SteveOllington]

Some of those same sites through compete.com:

As they use a combination of data sources I guess we'll have to stick with them...

[AlanBleiweiss]

I've never trusted compete.com data - every test I've done with their data has ranged from "wildly under-reported" to "wildly over-reported", with the occassional "lucky guestimate" thrown in.

[SteveOllington]

Yeah they do admit they estimate, based on their sampling. But I believe they mix panel with tool bar and ISP data, so I would have assumed their estimates would be kind of close but maybe not then lol.

Where do you use? I guess none can be trusted really can they?

[EGOL]

Thanks Steve,  I don't see an end-of-February drop for any of those sites in that data.
