If you are relatively familiar with HTML, create a single footer with links to all of your sites. After you've done this, you can use one line of html to make the footer show on all of your pages. Simple Fast Awesome
This is true but wouldn't it matter if all pages of content were relevant to links in footer? Remember if you conduct a visual page rank it will show pr of each individual link.
don't do it massivly, it won't really help, you might make a link farm linkink all your sites with togather.
this really isnt that great of an idea. (sorry to burst your bubble) I posted not too long ago on my blog how google is getting smarter at distinguishing networks of sites and subsequently devaluing links when they feel you are artificially trying to increase your rankings.
I've been reading the same and it just makes sense anyway. Google gets smarter and smarter every minute so the easiest way is to make the best business or content site you can so people will link naturally to you. It takes time and effort but in the long run it works a lot better than looking for short cuts. Not saying a few short cuts aren't a good thing, just to say they are harder to find.
Yeah but you are only getting links from 1 domain only. So all those links aren't as valuable as say 50 links each from a unique domain. Didier
