Zero Bandwidth Hits by SEs?

[Kavitha]

Hi,

One of my site got zero bandwidth hits by Yahoo and other small SEs. Is it lead to any negative result? Any idea to solve it?

Is your site in the Yahoo! index? Have you added new pages or changed content that you want indexed/re-indexed?

What are 'zero bandwidth hits' and why would you want to solve what?

The most likely cause is robots doing "conditional GET" requests using the If-Modified-Since header.

If the page has not changed since the date given in the request, your server will return a 304-Not Modified response, and zero bytes of page content. Some robots use HEAD requests to do this as well.

The purpose is to keep your pages' listings current without unnecessarily downloading pages that have not been updated since the robot's last visit.

Either way, the indication that CGETs or HEAD requests are the cause of these zero-byte responses is that the requested pages are those that you have not changed since the robot's last visit.

Thanks JdMorgan, I have updated my pages and now the hits are showing good bandwidth!

Zero Search engine Bandwidth hit is nothing but the hit to your webpages by any search engine with 0 bandwidth. The bandwidth should not be 0. If it is Zero it implies that the particular search engine doesn't crawled the page properly.
