There are many wordpress SEO tips and one of them is to interlink blog posts for relevant posts. But I have noticed one thing when I interlink blog posts on my blog. Example #1 <a href="http://www.mydomain.com/innerpage/">keyword</a> Example #2 <a href="/innerpage/">keyword</a> Technically both of them are actually links to my "innerpage" but when I use the example #1 option and publish the post, I immediately get a "pingback" request coming from my own blog. However when using the example #2 I don't get any pingback request. So which method of linking is good?
