I built a simple static website for my small business. I want to add a blog and product catalog / classified ads (about 50-100 products) without losing traffic & SEO. Only want showcase My products without allowing purchases. For the blog I would like to use Eleventy Static Site Generator. The question is, is SSG enough to create a product catalog / classified ads? Or maybe some other solution would be better?

I like when website works quickly and don’t like overloaded CMS. Eleventy seems very suitable for me, but I haven’t used SSG before. I know HTML, CSS, a bit of JS and PHP. I have used various CMS before such as joomla, concrete5, wordpress, automad, bludit.
