Does a Title Tag Add SEO Value?
If you use %anchor_text% more than once it is randomising it.
<a href="%url%" title="%anchor_text%">%anchor_text%</a>
Gives a different title to the hyperlink! This makes no sense to have a different title to hyperlink.
Surely the %random_anchor_text% macro should be the only one that randomises?
And I agree to @seagul - you never know how a traget site builds up their HTML tag for an external link so the chance to break their algo because of using title is quite high. And you might end up with bad links
The alt tag and title tag are very similar. The difference is that some browsers only read the alt tag and others read the title tag. Can't remember which ones read which tags.
These tags are a useful tool for onpage seo optimization. They are best used for images.
On linking, I have found it to be pointless, and even spammy. Say for example I have a link from a wiki going to my moneysite, and the anchor is weight loss. The last thing I want is a title called weight loss. I already took care of it with the anchor.
I used to do stuff like that a few years back. I remember taking a hit in rankings. So I de-optimized the site's interlinking among inner pages, and removed title tags on those inner page cross links. And I got my rankings back.
I can't prove it, but I am pretty sure Google has a little thing in their algo looking for over-optimization techniques like that. It is easy to spot, very unnatural, and completely not needed. So I give it a thumbs down.
