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.

What this plugin might earn a year, and what it might sell for. Modeled from public signals; we don't see anyone's books.

Est. annual revenue

Est. acquisition value

N/A

No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A small install base leaves thin data to model from.

    Only used very briefly so far, but, first impressions = Excellent! It’s the only cache plugin I found that works well with Wincache/IIS/Windows. It’s very clean and simple. The widget is useful, as are the statistics if you enable them. Does exactly what I want. The only thing I wish it would have as a really nice addon, is a way to pre-load the cache by visiting each post/page, though I can sort that externally. Not of failure of this plugin, but, it breaks the ‘simple download monitor’ download links for all files on my site. There is, due to the design of this plugin, an easy fix (though it errored on my site with a ‘needle’ not found or similar first time!). Enable ‘Exclusions’ and add ‘download_id’ to the excluded $_GET variables. Clear your cache, and downloads should work again. This is because download links are simply sent to the home page with the get variable. Probably a dumb way to do it, but… This topic was modified 3 years, 5 months ago by pjsgsy.

    If you use this right and read the instructions – none the better for its purpose. Combine it with Autoptimze and you’re good to go.
