Automate adding related, upsell and cross-sell links to your catalog based on most bought and most viewed.
Upload the files to the root of your Magento install. Let the install script run. This will create the table aydus_productlinks_log for logging purposes. In the System -> Configuration, go to Catalog -> Product Links and select the type of link data to add as related, upsell or cross-sell. Clear cache. Also set the time you want your cron to run.
