Googlebot HTML file size vs real file size

[followgreg]

I am looking at my logs right now and I am seing Googlebot crawling pages reported around 4kb while in reality the filesize is around 17-30kb (copied and pasted in notepad).

The HTTP code is 200 so no problem with this. But I am wondering why when Googlebot crawls my server shows only like 4kb downloaded?

Have I been hacked (again)? Or is there something I might want to check on my server?

Rather than viewing the offline filesize, check the size as delivered to your browser. For example, in Firefox, load the page, right-click and choose View Page Info.

The most likely reason is that you have GZIP compression enabled on the server - Googlebot supports GZIP-compressed HTML delivery.

If not, check the contents of the cached link (assuming you allow caching).

You are absolutely correct. We switched server last month and while the older server had no compression the new one has and I didn't know that. Thank you! Saves me a bunch of time and worries.
