Yahoo crawler used to come to our site once in few days.. we recently started second round of link development and we got about 20-30 new links in past week.. we had about 50 links earlier.
Since yesterday yahoo crawler is visiting the home page every 3-4 hours.. does that mean we have crossed some link threshold which qualifies us as a better site (compared to before)... we are getting hits from this crawler:
YAHOO-VERTICALCRAWLER-FORMERWEBCRAWLER/3.9 CRAWLER AT TRD DOT OVERTURE DOT COM; [ALLTHEWEB.COM...]

Although this url (HTTP://WWW.ALLTHEWEB.COM/HELP/WEBMASTER/CRAWLER) does not exists, but this is what we are getting in crawler identification.
