Huge drop in my blog traffic

[Northstar]

Over the last three days I have has a huge drop in Google traffic to 3 out of 5 of my blogs. I still have my PR and the domains are still listed but both keywords and Google image traffic went from around 600 to 6 per day. The blogs have almost nothing in common with each other, are not crosslinked and are on different IP's. I'm at a lost as to what would cause such a huge drop. Anyone have ideas?

Any comparisons to this time last year?

[Northstar]

No the google traffic was steady last year to all three blogs.

I've had many hit like that over last year, in groups.

Is strange you got hit but had no cross linking. Are you running adsense on the blogs?

Are they similar niches? Heavily optimized for certain keywords?

To be honest I find it very hard to diagnose with little info. You know best what you have done recently to your sites. Reach into your soul and find the answer :-).Perhaps it's a Google Caffeine thang.

my blog is experiencing the same issue I noticed the drop ever since I started running adsense on it

[totentando]

another thing that I did was placing a site map on my page, do you guys think that may have affected it? Northstar sorry for confusing the forum with own questions :)

[Northstar]

No I don't run adsense and the highest keyword density is only 2.8%

It looks to me like the drop was in image searches. I went from 400 to 2 hits per day from images.google.com. The odd thing is the three blogs wheren't related at all and the image searches were all different.

Something unusual is going on, we had one blog spike from 15 uniques per hour to in excess of 160 uniques per hour, all from Google and spread accross a large number of pages and long tail search terms. It lasted about 3 hours and dropped back down to the 15 level per hour again. For those of you who don't think traffic throttling exists then this sort of thing certainly needs some explaining.

When people say "throttling" I've always thought they were talking about keeping traffic below a certain level. What you're describing sounds like a temporary spike - and I've definitely seen that happen as data moves around. All of a sudden a site ranks well on a term for just a few hours - maybe days - and then that goes away.

To me at least, that's what I'd call a traffic spike, caused by some odd anomaly in the way data moves around Google's back end.

How many blogs does one need ?
I really don't understand people wanting blogs. I've never needed one. Never will have one.

If any of the search engines decide to disregard blogs in the SERPS, you will be stuffed for sure.

I'd rather make a real website with a real address. Much more professional, and less likely to be hacked... or should say, harder to hack.

It looks to me like the drop was in image searches. I went from 400 to 2 hits per day from images.google.com

Are these your images, or are they hotlinked from other sites ?

[tedster]

Or maybe the other way around: are other sites hotlinking to your images and stealing your rankings in Image Search. That can happen.

Do a Google site: search to ensure the site is still in the index. At the same time, make sure no pages are flagged with "This site may harm your computer," which is a common reason for traffic to suddenly disappear.

Check your Google Webmaster Tools for any reports of problems with the site: [google.com...]

Check your logs to ensure googlebot is still visiting.
