Biggest opportunity: Swap “cache”, “optimize” and “pagespeed” for “cache warming”, “people” and “high”. “cache” isn't earning its slot: you're not in the first 24 results for its own search. “cache warming” sits at #9 untagged, close enough for a declared tag to move it up. “optimize” isn't earning its slot: you're not in the first 24 results for its own search. “people” sits at #12 untagged, close enough for a declared tag to move it up. “pagespeed” isn't earning its slot: you're not in the first 24 results for its own search. “high” sits at #17 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

of downloads still active
At least 50K of 929.2K lifetime downloads are still running, above its category: the median Performance plugin keeps 1.4%, across 1,101 plugins.
Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Performance plugins, not across the directory. wp.org reports active installs as the bottom of a band, so the real rate is this or higher.
This plugin shipped 53 releases in the last 12 months, and every existing install that updated counted as another download. wp.org publishes no split between first installs and updates, so we show the raw rate rather than guess at one.

wp.org is where the directory puts the plugin for that search. On merit is where it would sit if results were ranked on rating, support and updates, without the install boost. The last column is how far the wp.org position moved, from our first reading in the last 90 days to the latest.

What to do about it

I have been using this plugin on my business directory site for a while now. It significantly improved our page loading speed and caching efficiency. Highly recommended for optimizing website performance!

I’ve been using Seraphinite Accelerator for almost five years. My knowledge of web technologies is exactly what I need to run my own site, pcminsk.by, but I’ve always been obsessed with its speed. At one point I tried half a dozen plugins, maybe even more – and only this one gave an obvious, instant boost, without endless tweaking and empty promises. I just turned it on and saw the difference. Since then the plugin has become my benchmark. I recently switched to the full version – and that’s a separate pleasure. The site got even faster, although it felt like there was nowhere left to go. And everything works out of the box, with no magic incantations or complicated workarounds. The main thing is the real performance gain, which I notice, and so do my visitors. Huge thanks to the developers for a product you can use for years and never be disappointed. A truly solid plugin.

I have encountered a problem: Google Merchant Center has started rejecting my products, supposedly due to a 500 error, even though my server is very powerful.

We discovered the Serpentine Accelerator plugin online and were genuinely impressed by the quality of their support. Even while using the free version, the support team was extremely helpful and guided us thoroughly. After installing the plugin, we noticed a clear improvement in our website’s speed. Overall, it’s a great value-for-money plugin with reliable support.

The performance of my site is now significantly better, I definitely recommend this plugin! Although I had some small issues with it, the support was super fast and fixed everything for me within a couple of hours.

I am skeptical, on the face it looks to work well, but since I installed it, the https traffic to my website has increased 1000% which is flagging issues with my ISP. I can’t quite put my finger on it, but I also suspect that this might be a bit too good to be true – I wonder if there is some suspicious work being done through this plugin to fabricate the results, which seem inconsistent depending on when you run Page Insights… This topic was modified 10 months ago by mitchb2992.
