Maybe I should have stuck with it for longer, or just made the site better. The idea was that the official Gazelle site listed their dealers behind a postal code search form, that couldn't be indexed by search engines. So I scraped it and presented each one on a separate page, with overview pages per city. Didn't manage to get a lot of traffic, but I was also super new to SEO back then.
Would have expected this could rake in some SEO traffic though, but surprised that didnt work for you. Or maybe surprised isnt the right word, maybe i have the initial high hope for it when you registered it and tried it :)
