There are links from pages as high as PR5 and low as PR0 pointing to this site's front page. There have been no hits from the crawler, even on robots.txt, in over a month. The MSN bot visits very often.
I've searched, and most of threads like this relate to new websites, or new webmasters learning that websites need incoming links for google to visit. This page had been listed in the SERPs for months and crawled almost daily until early May.
I'm pretty sure this is unusual. Has anyone else seen this happen? Is there anything I can do to bring back the crawler?
a new host may help in a couple of scenarios. 1) you have been identified as part of a incestuous nest.Moving host may just help you get outside that loop. 2) there is a problem with your hosts setup similar to the one godaddy had 6 months back which disallows search engine crawling. Putting new content on your page may help if you have a competitor cloning your site. Of course these are longshots but worth trying. You just may also have a penalty for hidden text or something or google may have flagged you for spam of some sort and you maybe on your way out.:(
