Somewhere in DP i saw a guy who created autoping scipt for his forum which pings google every time a new thread is started. Do you think its a good idea? I have a forum with 15,5k members and ~100 new threads daily so it basically would ping google 100 times a day. Wouldnt google mark it as some kid of spam?
i don't think it is of any use as you can't command Google to come to your site whenever you want. moreover, sending a signal that you have updated something too is of less importance
The crux is what "content" comprises. A forum is expected to have content that changes more or less by the minute, and it would be folly--and doubtless piss the SEs--to ping for every new post. Ordinary site pages are another matter. Using the tool in my sig block, I have a dozen or so sites for which 100K+ pages change, at least to some extent, daily; I auto-ping the major SEs whenever a day's update run is completed, and my sites seems to have done pretty well over the years.
Ping is not important , if you have quality links, quality content your spiders would love to visit your website.
exactly... you do not need to ping every time when you update content. If your have some potential web links, crawlers will automatically follow and index your content...
If you have a regularly updated blog with PR2/3 (or more), google often indexes new content rather quickly.
While all the remarks about what the SEs "automatically" do are probably correct, they ignore the basic principle of success (at SEO or anything): If it can't actually hurt, do it. There's no measurable cost associated with pinging the SEs when there are changes in your pages; so why not let them know, just to (as Shakespeare put it) "make assurance doubly sure"? It might get you visited sooner, or more often, or it might not; but, again, it can't hurt, so why not do it? That is especially the case if your site contains a large number of dynamic pages whose content--or even numbers and names--can and do change frequently. The package in my sig block produces a block of files that really does change, at least somewhat, from run to run (typically daily); it automaps its results and auto-pings the SEs daily, and the results seem to be pretty good.
Pinging google isn't that necessary. Google automatically crawls the site when new content is posted in it.
