Check out https://linklicious.me/. They have free memberships available that will allow you to ping your links.

If you use wordpress it does the ping for you and you can add additional ping services to the default ping service.

Ping.fm if you have a site. Pingler, Pingoat otherwise.

ETA: Didn't see your bit about not knowing how. Pingler and Pingoat are fairly self explanatory. Put in your main URL, OR the url of the page you want pinged (always ping a new post, new article, new page, etc., anything that has a different url). If your site/page has an rss feed (usually found at http://NAMEOFYOURPAGE.com,.org,.net,.info/feed), put that in the appropriate place. Pick ALL the service for pinging. At the least, you will ping most, and at the worst, a few may say you can't ping there but no harm in trying. Choose an appropriate category if necessary and hit the ping button and wait for confirmation that the ping is done.

As far as Ping.fm, it's a bit more complicated, as you have to join any sites you want on your ping list. Once you've joined them though and put your username and password in Ping.fm for each account, it's automatic. Let me know if you need more info, be glad to help.

You can use ping services like Pingomatic. You just enter the name of your blog (or article, etc), the web address, and feed address (if applicable).

You can do a simple google search for ping services and you should turn up quite a few.

Word of advice: Just pick one ping service that has a fair amount of services on it. You don't want to ping all over the place, because it could blacklist whatever you are trying to ping.

What do you want to ping exactly? I don't suggest pinging a lot of created backlinks as this can cause Google to flag your site.

for pining URLS I use PingFarm or BulkPing. I like these becasue I can mass ping with them. Example: Hire a freelancer to do 50 forum profiles, get the report, ping all the profiel pages....

For RSS: PingOMatic

For Social Bookmarking new blogs posts SocialMarker

Pinging is much more important than most people realize. If you are doing volume link building (with cheap links like profiles), Google will only find a very small percentage of the links. A given profile isn't generally linked at all, so there is no way for Google to find it unless it just so happens to crawl when that profile is a 'new user' showing up on the home page.

When you ping you point Google directly to the page that has your link on it. Once google crawls it, you get credit. Note that you DO NOT need to have the link indexed for it to improve your rankings.

There are other nuances with pinging like number of times you ping, if you track crawls, and the overall value of RSS feeds. But the bottom line is with pinging you can get full credit for your links. And since 100% get found instead of 5% you can probably cut back on your expenses!

Just use the site like - pingomatic or else pingoat. Put in your site url and click for ping. It will do the ping business.

Can I ping my blog post or is it my blog I ping? I prefer to ping each blog post
