Building a directory website is exciting until you realize it’s way more complicated than installing a theme and adding listings. Most directory owners tell me the same things: “I bought a theme thinking it was plug-and-play — it wasn’t.” “My search filters don’t work the way users expect.” “The listing submission process is confusing.” “Members aren’t upgrading because the monetization isn’t clear.” “The site feels slow… and support keeps telling me it’s fine.” IF ANY OF THIS SOUNDS FAMILIAR, THEN YOU ARE EXACTLY THE KIND OF CLIENT I HELP Hi, I’m Goodness, a Directory & Membership Website Specialist focused on Brilliant Directories, WordPress directory themes (ListingPro, MyListing, Listeo, Directorist, ListingHive, Listify), and fully custom listing systems & apps.

I build directory-based businesses that attract listings, convert visitors into members, and generate recurring revenue. WHAT I SPECIALIZE IN Brilliant Directories - Customizing BD themes, widgets, and modules - Member dashboards, listing forms, and paid plan structures - Search filters, geolocation search, maps, and SEO URLs - Monetization: paid listings, featured spots, membership levels WordPress Directory Builds (ListingPro, MyListing, ListingHive, Listify, and more) - Custom fields, listing logic, map search & filtering - Frontend submission systems - Payment integrations (Stripe, PayPal, memberships) - Directory speed, caching & mobile optimization Strategy, Optimization & Repair - Fixing broken directory structures - Cleaning up messy fields & taxonomies - Improving low-converting membership pages - Making directory search actually useful - Ranking category pages & listings for SEO I bring together technical skill, user experience understanding, and monetization strategy to make your platform not just functional but profitable. If you want a directory that loads fast, converts members, ranks on search engines, and actually works the way users expect, you’ll want someone who specializes in exactly that and that’s what I do every day. Send me a message with what you’re building or what’s currently frustrating you and I’ll help you turn your directory into the platform you envisioned.
