Advice Needed. Online Mall

I have been thinking about starting up a new Online shopping mall. Actually been thinking about it for awhile but not quite sure how to go about it. Any advice will be greatly appreciated!!

There are many advice that could be given. One is that if you are going to optimize for the search engines, then I suggest all your pages interlink to another webpage (Google will LOVE you for this, and not to mention if your site has hundreds or thousands of links, then they will be considered backlinks to rank you higher.)

Take a look at myweddingfavors.com to see what I'm talking about. The owner of that site is Brad Fallon who's a professional SEO expert.

Online mall don't work.
Stick to one product or one niche.

The best way to make an online mall work would be to get lots of affiliates to promote your mall.

Cheers
