Google Ads audit needed For My Web Design Service

Google Ads audit needed – web design service, dedicated landing pages, zero conversions I am a small freelance web designer/developer based in Carmarthen, Wales. I build business websites from £500 (brochure sites for local trades and small businesses). I’ve spent about £250 on Google Search Ads so far with no conversions (no quote form submissions, no booked calls, no WhatsApp enquiries tracked as leads). At £500 per website, I’m already at a loss and need an honest, expert review of what’s wrong before I spend more. What I’ve already done (please don’t suggest “get a landing page” — I have them) Dedicated landing pages — final URLs match the ad intent (not sending traffic to the homepage). Exact match keywords only — no broad match; tight control over search terms. Location campaigns for Wales towns, e.g.: /web-design-development/swansea /web-design-development/cardiff /web-design-development/carmarthen /web-design-development/llanelli /web-design-development/wales Trade campaigns (UK-wide), e.g.: /web-design-for/plumbers /web-design-for/electricians Landing pages include: Clear headline + local/trade-specific copy Pricing from £500 Multiple CTAs: quote form, WhatsApp, book a call Portfolio examples (real client websites) FAQs, “Who am I?” section, mobile sticky CTA bar Tracking in place: Google Analytics 4, Microsoft Clarity (session recordings), live chat (Crisp) I'm not sure what to do next because doesnt seem to be working could just be the amount of clicks isnt enough which would be bad because I'm paying £5-£10 a click.
