What's the difference between these anchor links?

I'm just wondering what's the difference between the following in terms of their effect in building links back to your website. Say for example you use them in your resource box in your submitted article?

1. http://yourdomainsample.com

2. <a href="http://yourdomainsample.com">Relevant Keyword</a>

3. <a href="http://www.yourdomainsample.com">Relevant Keyword</a>

I think all will take you back to the pointed website but would one be effective (Search Engine Ranking) than the others or they're all just the same?

I've just noticed that when you use the site explorer to check backlinks to your site. A search of www.yourdomainsample.com will give you different result than searching http://yourdomainsample.com

I hope I posted this to the right section, please pardon me if I didn't.

Cheers

 

As far as Google is concerned, http://yoursite.com and http://www.yoursite.com are two different urls. It is really important that you employ consistency from the word go, if you want to gain the maximum effect.

 

Anchor text gives You better position in SERP's on (Anchor= keyword), so 2 and 3 are "better" in SEO. The difference between 2 and 3 is that for search engines, these two domains http://www.sampledomain.com and http://sampledomain.com are two different domains. The best idea is to make a redirect in .htaccess to point both on "www" or without "www" - I preffer redirecting on "www".

 

You are searching for links pointing to www and non www versions of the domain.

 

Here's a blog post from Matt Cutts from google on the issue that should help you out.

Excellent article.

Would like to add that you can resolve this issue within Google's Webmaster Tools. There is an option for which version (with www or not) you would like all pages to resolve to.

 

You can use a redirect in .htaccess so only one gets indexed for all search engines. If you're using Wordpress, the latest version does it automatically to which ever one you specify under Settings. The point is to only let one version get indexed.

 

i like that topic

 

Thanks for sharing this info. I never knew www.yourdomain.com and yourdomain.com were 2 different sites. Does that mean if Ive been promoting both. It will be half the effect?
