Has anyone had this radical a Google Dance experience? Please comment and share!

I've posted a little about this experience in some other threads. But it continues, and I'd love to hear whether this is "normal" or unusual, and about some other experiences.

I am a "seasoned newbie" - been working at this for awhile, have about a dozen affiliate/adsense sites up, made a few dollars here and there.

But over the past two months I've had what to me seems like a weird experience with TWO sites that are "dancing" together.

The two sites are in the same niche. One is my "main" site, the other was set up as a feeder.

Both have original content. The main site gets updated periodically with new content. The feeder is an autoblog now.

BOTH sites are about 6 months old.

Well after inching their way up for awhile, back around the beginning of May, BOTH sites suddenly landed on page 1. For a few week or so.

Then they BOTH went (simultaneously) to page 500+ -- for a month.

Then BOTH suddenly were back on page 1 in mid-June - for 1 week.

Then BOTH back to page 500+ at the same time.

The a week ago, both back to page 1 - this time with a PR2 and PR1.

And again, now after 1 week, back to page 500+.

I've included screen shots of the traffic graphs starting April 1.

So has anyone else had this kind of experience - with TWO SITES dancing "side-by-side?"

Any comments or insights would be greatly appreciated! Thanks!

Hmm. Strange stuff (I have no clue why this is happening).

But, I have allways wondered (since Google allready are getting all your site´s data through Google Analytics). Would they use your bounce rate as a ranking factor? Because that would probhably have explained a lot in some cases.

By the way, did you use automated linkbuilding tools to rank?

It's called back-link fluctuation that's doing this - are you doing mass back-linking if so it's best to know who you are back-linking from. Maybe your back-links are not sticking while new ones are just being indexed.

Thanks to you both for some insights on this. Only backlinking at this point is ongoing article submission and social networking bookmarks. But in both cases, I'm using a submitter (but trickling them out over time). Funny thing is, I don't do any link building for the feeder site anymore - but it is obviously "attached" to the other site by Google.

While these two sites have been my biggest traffic generators (when ranked lol) I'm not getting rich on either. So it's kind of a good lesson/experiment/test to see what happens.

Thanks again - and if anything else comes to mind, I'd love to hear.
