I have another small idea that might help you gain some goodwill and some link-love. You mention on your site that you have a "curated list of WordPress plugins", which I assume means that, for any request I have, you can tell me the best plugin to fulfill that request. Now obviously, since you're selling this as a feature, you assume (correctly) that this is a competitive advantage worth paying for. However, you might want to consider releasing the curated plugin list. Maybe only parts of it, maybe not forever, but this is something that people often need, and if your site comes up first for every search of "best plugin for Wordpress that does X", you might get a lot of potential customers just through that.
