I'm not sure if it would still be helpful, but yes, that likely did have an affect on your rankings simply due the broad amount of titles being not quite targeted search pool. If you're still in business as of now, in such case you should try creating a platform with Shopify - provides straightforward tools for beginners and allows complete customisation for advanced users. I was hired by Goodevas to design their website way back, a lot have changed but the backbone is still the same. You can see how the titles are evenly spaced out. Hope that helps
