Biggest opportunity: Add “rdf”, “donate link” and “xhtml” to your wp.org tags. You rank #9, #13 and #16 for them without listing them, close enough for a declared tag to move you up. WordPress.org counts only your first five tags, so with 0 listed these are the slots worth spending.

of downloads still active
At least 20K of 510K lifetime downloads are still running, above its category: the median Uncategorized plugin keeps 0.6%, across 17,771 plugins.
Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Uncategorized plugins, not across the directory. wp.org reports active installs as the bottom of a band, so the real rate is this or higher.

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.
| Keyword | wp.org | On merit | wp.org move, 90 days |
|---|---|---|---|
| comet | #1 | #1 | 0 |
| donate uri | #1 | #1 | 0 |
| rdf | #9 | #5 | up 1 |
| donate link | #13 | #7 | 0 |
| db cache | #8 | #4 | up 1 |

What to do about it

Update activity
How busy the existing users are, measured as downloads in the last 30 days for every 1,000 active sites. A spike means a new release everyone's pulling; a long, slow decline means an aging user base that updates less.
Release cadence
No release in a yearHow often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

dead project, period. It’s never been developed since 2017… cause the 170220 update was posted on Facebook in February 2017 This topic was modified 2 years, 7 months ago by Francesco. This topic was modified 2 years, 7 months ago by Steven Stern (sterndata). Reason: removed link

I have used this product on a couple of websites I have built and have had positive results, however after a few days of operation, on one of the websites, the product would produce a visible text error on top of the home page of one of the websites I used it on. This was regardless of the way I configured it, and the cache had to be flushed to resume normal operation. This plugin also has paid versions that add some capability to an already good product. I eventually switched to a different product as my standard for commercial websites, but still believe this product to be one of the better cache plugins on WordPress.org. It is a good product, and I recommend downloading the latest free version and running it for a few days to determine compatibility with your specific website!

Perfect for a site with static pages (e.g. with no user comments, etc), it generates html pages on the fly, super fast, good results in google speed test.

Funktioniert als “stand alone Anwendung” gut, also ohne andere Pugins. Eigentlich nicht das was ich mir von einem Cache Plug und einem “Pro Plug-In” erwartet hätte. Macht Probleme mit MonsterInsights Pro und dem blog2social Plug z.B. Was auch noch ein ganz großes Minus ist, es findet keine wirkliche Admin-Warnung statt, so als selbst-Test so zu sagen, ob das Plugin fehlerfrei läuft oder nicht.

Comet Cache is the most easiest to use and setup caching plugin which sped up many of my clients sites which were lagging real bad when none of the other caching solutions were working properly out of the box. Its such a pity that perhaps the best caching plugin for wordpress has been abandoned by its developers, i wish we could do something to help !

I BEEN USING W3 Total Cache for a month and I see the effect and the speed of my Website its like 6-8sec. but when I try comet-cache my eyes could not believe it from 6sec to 1.2 secs what a huge difference, you save me from purchasing wp rocket plugin. especially im only starting my website for my business. Someday I will purchase the license.

It just works. And on sites where other caching plugins actually slowed things down!
