Duplicate requests by Mediapartners bot

[pashenG]

Hi.

I see that Mediapartners bot makes duplicate requests for
lots of my pages. i.e.

66.249.65.137 - - [04/Jun/2005:17:18:00 +0200] "GET /file.html HTTP/1.1" 200 14248 "-" "Mediapartners-Google/2.1"
66.249.65.137 - - [04/Jun/2005:17:18:01 +0200] "GET /file.html HTTP/1.1" 200 14248 "-" "Mediapartners-Google/2.1"

Is it normal?

Regards.

I noticed the same happening on one of my sites, which is new.
On my old site each request is single.

No idea why ;o)

My site has five years. It has stable position in google SERPs.

For me it is waste of resources to download many pages twice.

I have this since I joined google adsense 8 months ago.

From my logs:

66.249.66.166 - - [04/Jun/2005:23:47:30 +0300] "GET /file.html HTTP/1.1" 200 21065 "-" "Mediapartners-Google/2.1"
66.249.66.166 - - [04/Jun/2005:23:47:31 +0300] "GET /file.html HTTP/1.1" 200 21065 "-" "Mediapartners-Google/2.1"
66.249.66.166 - - [04/Jun/2005:23:47:31 +0300] "GET /file.html HTTP/1.1" 200 21065 "-" "Mediapartners-Google/2.1"

As i can understand, this is meant to be as test for static content/fast changing dynamic content. There can be scraper- and spammerscripts, generating new, random content EVERY TIME. And so mediabot can be sure, that crawled content stable in some degree.

Guys,
If you have 3 ads blocks - you will have 3 requests
2 ads block - 2 requests.

What is wrong here?:)

I only have one ad block on my site and I still get two requests.

I don't know the exact time it started but I have been seeing the same for quite a few months, two requests for the same file with one second difference and only one ad block per page

[Staffa]

Same here, one ad block = two requests

[pashenG]

I also have one ad block per page.

I added another block, and now have 4 requests...
