Understanding layers stops “I purged Cloudflare but wordpress">WordPress still shows old content” confusion.
Browser cache
- Honour cache headers for static assets; version filenames when you deploy breaking CSS/JS changes.
Page cache
Serves full HTML for anonymous visitors—great for blogs; careful with cart and logged-in experiences.
Object cache
Speeds database-heavy WordPress by storing query results in memory—helpful for WooCommerce at scale.
Frequently asked questions
Why do I still see old pages?
Multiple layers may cache—purge systematically from edge to origin.
Does caching hide updates from editors?
Exclude admin and preview URLs; teach editors to use hard refresh when testing.
Putting this into practice on your NZ website
This guide sits in our Speed & performance collection. The goal is practical advice you can act on without a computer science degree. Start with one change, measure whether enquiries or usability improve, then tackle the next item. Small businesses across Auckland, Wellington, Hamilton, Christchurch, and regional New Zealand face the same constraints: limited time, real customers, and a website that must earn its keep.
For Caching layers explained simply: browser, page, and object cache, the highest-leverage move is usually to align your live site with what the guide recommends, then fix anything that blocks Google from crawling pages or stops visitors from contacting you. If your site runs on WordPress, many of these tasks are configuration and content work rather than custom development.
Document your starting point: note current enquiry volume, average page speed from PageSpeed Insights, and any errors showing in Google Search Console. Without a baseline, improvements are guesswork. Revisit the same metrics after 90 days—SEO and UX changes rarely produce overnight miracles, but sustained progress should be visible in leads and user behaviour.
Share this guide with whoever maintains your site—an employee, a contractor, or your hosting support desk—so terminology and priorities align. The FAQ section on our main site answers common project questions if you are weighing a rebuild versus incremental fixes.
Before committing to changes, run your current site through our free website checker to see speed, mobile usability, and basic SEO signals in one report.
When to involve a web partner
Some tasks—migrations, checkout changes, security incidents, or a full redesign—benefit from experienced help. If you are comparing providers, look for clear scoping, realistic timelines, and measurement tied to business outcomes rather than vanity metrics. Our team builds and maintains business websites nationwide; explore relevant services below or request a quote when you are ready.
A good partner will ask about your customers, geography, and capacity to publish content—not only colour preferences. Review our recent website projects for examples of brochure, WordPress, and ecommerce work across New Zealand.
