Short answer first, then the detail. WordPress theme bloat matters for WordPress vs custom ranking — here's exactly how and what to do about it.
Get this done in one sitting
A practical sequence that we apply across UK plumber, dentist and accountant sites. Adapt names; keep the order.
- Take a 30-second baseline measurement of the current state (screenshot the page, save conversion rate).
- Identify one specific page where the change has the highest traffic × conversion leverage.
- Apply the WordPress theme bloat fix to that single page first — keep the rest as a control.
- Wait 14 days minimum before reading results. Earlier is noise.
- If lift is positive, roll out site-wide. If not, debug — usually mobile rendering or schema.
The mistakes we see on most UK audits
Three patterns we see repeatedly when WordPress theme bloat work goes wrong:
- Confusing best-practice with actual practice. Textbook advice on WordPress theme bloat sometimes lags 18 months behind what's actually ranking. Stay current.
- Buying a tool before understanding the problem. The right tool helps. The wrong one costs £50/mo and adds work.
- Doing this for the wrong audience. UK customers behave differently to US customers. International best-practice often needs UK-specific adjustment.

Where most owners go wrong here
Astra vs GeneratePress vs custom theme — measurable impact. If you've already read about this elsewhere, you'll have heard it framed as a 'technical' issue. It isn't really — it's a business issue with a technical surface. The conversation belongs in your strategy meeting, not just your dev queue.
The data backs this. ICO GDPR guidance and WCAG 2.2 Quick Reference both publish UK-applicable research that confirms the pattern. Skim the linked pages if you want the raw numbers.
