Automate website, SEO, Open Icecat integration

I have a Zencart v1.5.5d installation. I had an optional insurance module and a Bid or Buy feed generator installed, but they did not work properly - I think the Bid or buy one didn't work as I didn't have an ssl site at that time. I have been manually adding products via easy populate as I get stock lists daily from most of my suppliers ( many of them don't have product feeds on their websites)but would like to automate my site, possibly with open icecat integration as well as SEO? This might save me money instead of paying someone to manually find pictures, weights, categorize and manually find new products from suppliers lists?
