If your site is bogging down from too many "just looking" visitors or if you're not seeing your Miva Merchant store in search engines results, then Merchant Optmizer 5™ is the perfect tool for you. Merchant Optmizer 5 works by creating exact copies of your Miva Merchant store's screens, saving them as standard HTML pages in an alternate directory.
These static pages are much easier for your server to serve to your customers and for search engines to scan and index. With a few additional tricks, you can direct all browsing to be done in the static pages. Or, you can just use the static pages as entry points for your Merchant store's dynamically generated screens.
You can create separate static pages for different affiliates, or even for different domains. For example, you can create a mirror site on a different domain that's and exact duplicate, or has a different look and feel from your store.
(This second store could be configured with an affiliate link, and those hits tracked by any compatible affiliate module such as Merchant's built in affiliate module or a third party module.)
