I read a thread where there were tons of suggestions for pinging sites, like pingomatic, pingler, autopinger, etc…
I realize you only really want to ping when you have changes or if a long time has passed, but is there any positives in pinging with say, all 3 of the above sites every time a change is made, or will that be considered duplicate pinging and u will get blasted? I.e., basically are all ping sites the same at the core of their functionality? Or should you at least rotate using each one every week or so?
Also, anyone know much about the Wordpress auto pinger? Do u really need something like the WordPress Ping Optimizer to make sure WP doesnt spam the ping every time u save? Doesnt make sense bec I bet most people dont use something like the WordPress Ping Optimizer, which means most WP sites get tagged as spammy?
