Recommendations
Recommendations is a short checklist nsin builds for each domain by looking at your real traffic and your settings. Green ticks are things you’ve already got right; warnings are things worth fixing, each with a button that takes you straight to the setting.
Nothing here probes your website. Every check is answered from data nsin already has — the request logs from your own visitors, plus your domain configuration.
What gets checked
Section titled “What gets checked”| Check | It warns when | Fix it with |
|---|---|---|
| Caching | No request was served from cache and no cache rule exists. | Cache rules |
| Response time | Your average response time is slow. The slowest addresses are listed, with why each one skipped the cache. | Caching |
| Server errors | Too large a share of requests failed with a 5xx. | Your server; see Uptime |
| Image format | Most of your image traffic is still JPEG/PNG where WebP would be much smaller. | Your site |
| Certificate expiry | Your certificate expires soon and won’t renew itself. | SSL |
| robots.txt | Crawlers are asking for /robots.txt and getting nothing. | Your site |
| Sitemap | No sitemap is being served. | Your site |
| HTTPS redirect | Visitors arrive over plain http:// with no rule sending them to https://. | Redirects |
www reachability | Your www address doesn’t resolve to nsin, so visitors typing it never arrive. | DNS records |
www redirect bypass | You have a www redirect rule, but the www record isn’t proxied — so the rule never runs. | DNS records |
Reading a recommendation
Section titled “Reading a recommendation”Each item shows a severity, a plain-language explanation, and the numbers behind it (hit rate, average response time, error percentage, and so on) so you can judge it yourself rather than taking the verdict on faith.
Items are grouped by what they affect: speed, SEO, reachability and security.
Why some checks don’t appear
Section titled “Why some checks don’t appear”Rate-based checks need enough traffic to be meaningful — a handful of requests can’t tell you whether 2% of them failing is a problem. When there isn’t enough traffic yet, the check is simply left out rather than guessing.
Results are recomputed every couple of minutes, so a fix shows up shortly after you make it — not instantly.
Dismissing
Section titled “Dismissing”If a recommendation doesn’t apply to you, dismiss it and it moves out of the way. Dismissals are per person: dismissing an item doesn’t hide it from other members of the domain. You can restore a dismissed item at any time.
Common questions
Section titled “Common questions”I fixed it but it still shows a warning. Give it a few minutes — the checklist is recomputed on a short cycle. Traffic based checks also look at a rolling window, so a metric takes a while to move.
The image check flags images I can’t change. Dismiss it. The check is advice, not a requirement.
Nothing is listed at all. Either the domain hasn’t received enough traffic yet, or its plan doesn’t include monitoring. See Plans.
