If you've ever wondered about switch website platform, this is the short answer in 800 words. Part of our deeper pillar guide on WordPress vs custom.
From 'I should' to 'I did'
Implementation guidance below assumes you're not a developer. If you are, skip to step 3.
- Open Google Search Console and note your current ranking for the keyword cluster.
- Run a Lighthouse mobile audit on the page you're changing — note the LCP and CLS scores.
- Apply the change in a low-traffic window (Sunday morning works for most UK businesses).
- Verify schema using Google's Rich Results Test before moving on.
- Measure call volume + form fills over the next 30 days against a matched baseline.
Where well-intentioned owners trip up
Three patterns we see repeatedly when switch website platform work goes wrong:
- Trying to fix everything at once. Prioritise. One page, one change, one measurement window.
- Outsourcing the thinking. Agencies you don't trust to think will execute, not lead. The strategy stays with you.
- Forgetting the customer. Every switch website platform decision is ultimately a customer-experience decision. If it makes the visit harder, undo it.

The short version (read this first)
There's a reason switch website platform keeps coming up in our audits: most UK SMB sites get it 60-70% right. The last 30% is where the actual lift hides. Re-platform vs rebuild vs refresh — costs and timing.
The data backs this. Schema.org and Think with Google both publish UK-applicable research that confirms the pattern. Skim the linked pages if you want the raw numbers.
