Client-side analytics collects information in the browser. Server-side analytics collects it during a server request. Collection location and data storage are separate decisions: SlimStat’s browser tracker can send data to your own WordPress installation.
Which approach fits a WordPress site?
| Question | Client mode | Server mode in SlimStat |
|---|---|---|
| Does it work with full-page caching? | Yes, when the tracking script and endpoint can run | Not for responses that bypass WordPress PHP |
| Does it require JavaScript for collection? | Yes | No browser script needed for server-recorded pageviews |
| Can it observe browser interactions? | Supported interactions can be sent by the tracker | The page request alone cannot see later clicks |
| Can blockers affect it? | Scripts or requests can be blocked | Browser script blocking does not stop PHP execution |
| Where is SlimStat data stored? | Your configured database | Your configured database |
| Are consent and filters relevant? | Yes | Yes |
Choose Client mode for cached pages
A full-page cache can answer a visit without running WordPress. Client mode sends a separate request from the browser, so it is the practical starting point for these sites. Check cache and minification exclusions if visits do not appear.
Consider Server mode for uncached pageviews
Server mode can collect eligible requests when WordPress renders the page, including when JavaScript is unavailable. It is not a promise of complete sessions or automatic order tracking. Bots, exclusions and consent choices still matter. Follow the Server mode setup guide.
Compare cost and accuracy on your site
Use the same URLs, traffic pattern, consent choices and cache state. Check both page delivery and report response time. A higher count after switching modes can reflect bot handling or changed session grouping as well as newly observed visits.
SlimStat 6’s development performance measurements describe specific database operation reductions. They do not prove that one tracking mode is faster on every host.
What about privacy?
Configure what to collect and retain whichever mode you use. SlimStat’s IP protection and GDPR Compliance Mode are configurable, not automatic. Review consent integration and test both acceptance and rejection.
