Alerting search engines that you’ve updated your website and would like to have their spiders re-crawl the domain can be accomplished by ‘pinging’ them with your URL. This feature is built-in to most popular blog and CMS platforms (like WordPress) and will automatically ping various networks anytime that you save or publish something new. Sometimes though it can be beneficial to ‘help’ this process along, especially if you’re creating a site from scratch and don’t have any sort of auto-ping functionality built-in.
Two websites that will ping a long list of services for you are Pingoat and Pingler. These are both great resources for any website developer.

I’m a big fan of Pingler in particular because it lets you modify the list of services that it will contact when you use it.

Now there are many blackhat, whitehat and well “greyhat” uses for pinging these services to let them know of a site update, all of which are hot-topics for debate (which I won’t get into just yet). Just a word of caution though – You can easily get de-indexed if you ping Google too often, as well as from a variety of other search engines…so with that said, you’ve been warned. Don’t abuse this service!

For those of you looking for a full list of URL’s that allow you to notify them of updates, i’ve provided such a list below. It also includes all the international URL’s for Google’s Blogsearch. Keep in mind a lot of these actually will ping multiple resources so if you use them all, you’ll be hitting a large number of duplicate services….just a heads up. Enjoy.
