Back Link Quesiton (with PHP include)

I have goals of launching 100+ niche sites in the next year.

To make the most out of each site I want to cross link them all (have links to all my other sites on each site (100+ back links off the bat ).

My question.

To avoid having to update all the sites every time a new one goes live with the new link , i am planing on doing this -

As each site will be PHP based I am thinking (for the links page that is) of using an php include('xxx') statement and just pulling from a master link list from one source. This way I only have to update one page with a new link and it will populate across my network.

Will this method hurt my SEO?
Is their a better way of cross linking all the sites?

My reasoning for using this method is that PHP is server side code that when phrased for the browser (or spiders) it will look like its all coded on the site in question and not pulled form someplace else. The only drawback of this I can think of is the extra strain of bandwidth on one of my sites that hosts the master list.

However if this is ok - you can use a like method with rotating banners. (include a php file that display a random banner - this is hosted on only one site so if you have 50 sites - all of them can pull from the same banner pool, and you can just update that one banner pool when you get more adds).

Thanks for your help!

I don't see anything wrong with this. I use to do it for my black hat sites. You are correct with it not making a difference to the Search Engines. PHP includes certainly are handy. I like using it to change advertising across multiple sites in the same niche.

Excellent then!

This will make updating links much easer as well as rotating banners as you mentioned!

Thanks for your feed back. Happy Black Hatting to you.
