As you already know, Wordpress by default includes only pingomatic in its ping list
Don't get me wrong -- this is a good service, just that it only lists a very limited number of ping sites.
Would you like to expand this list and add more links into your arsenal?
Now you can add the best pinging services to your pinging list, at no charge whatsoever, and start using the Ping Optimizer plugin to get your blog linked into these blog directories/sites.
That's free potential traffic for you! :)
So, Here's a step-by-step GUIDE which gives you a fresh list of ping sites and how to LOAD them into Ping Optimizer.
We've searched the Internet for the best and most up-to-date wordpress ping list sites to use on your wordpress blogs. Finding them can be tough, and finding an updated list can be even more work. But, you don’t have to worry about going through that step because we’ve already done that part for you. All you need to do is just copy and paste the active ping list provided below and you're good to go.
After research we have categorized the whole ping list into three sections:
1. Must Have Ping Services
2. Other Working Ping Services (From Various Services)
3. Sites Removed From The Original Ping List (Just for information)
Pick and mix (category 1 and category 2) pinging services as you see fit:
