There's no need for you to ping all your links, this is exclusively relevant to a website or weblog to notify a server that has a new content update. FYI, it shows that ping sites help your site stand a chance to get indexed/listed on search engine quickly.
I've learned that some high PR sights like Google Plus and Wordpress.com pages are hard to index now a days, unlike bloggers.com sites and other web 2.0 sites. It requires unique title and content on your posts. It's a must that you add the url to google webmaster tools, but on top of that, you need to use bookmarking and backlink indexing services.
Submission to blog networks :
We talk about blog directories and blog networks as though they were things of the past, but in fact even today networks and directories work. As in the past, however, you should not submit your blog to every blog network or directory. Instead, submit your blog only to selected blog networks and directories, making sure to avoid link exchange directories!
Sitemap submission :
A sitemap is created to help search engine crawlers to effectively crawl your blog, so make sure you have created a sitemap for your site or your client’s site.
Commenting dofollow/Comment Luv:
Popular website stats program :
Some of you may not be aware of websites which keep stats of domains or show the price and value of any domain. This is a nice way to get your site indexed, however submitting to multiple stat sites is not easy, so we want to use free tools like IMT website submitter. With this tool, all you need to do is to add the link and anchor text, and IMT submitter will submit your site to sites like who.is, “website stats” and other such sites.
Social bookmarking submission :
This is another very effective method, though somehow within four hours my website was in the search engines despite the fact that I did not seek social bookmarking submissions. If you wish to do so however, you can start with Google Plus, Stumble Upon, Facebook (public share), and Twitter for faster indexing of your content.
If your budget is sufficient and you have the necessary time and patience required, prepare 5-10 quality posts and ask your fellow bloggers in your niche for permission to publish your articles on their blogs as a guest author and enjoy the resulting backlinks.
Ping services offer another effective way to notify search engines of your existence. Pingomatic is one such tool which you can use to notify multiple search engines at once, and another you can try is Pingler. Wordpress does have a default feature to ping services, but giving one of these other options a shot can’t hurt.
