Biggest opportunity: Swap “captcha” for “spambot”. “captcha” isn't earning its slot: you're not in the first 24 results for its own search. “spambot” sits at #22 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 100 of 27.9K lifetime downloads are still running, below its category: the median Security plugin keeps 1.4%, across 1,060 plugins.

Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Security 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
spambots your tag	#22	#16	0
spambot	#22	#16	0
captcha your tag	Not in the top 24
login form your tag	Not in the top 24
new user your tag	Not in the top 24
security your tag	Not in the top 24

7 searches this plugin appeared in over the last 90 days, 2 listed. 5 left out as unrelated or noise (years, numbers, stray words). 4 of its tags aren't in the top 24 for their own search.

What to do about it

Swap “captcha” for “spambot”. “captcha” isn't earning its slot: you're not in the first 24 results for its own search. “spambot” sits at #22 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

I immediately apologize, but for whom you write such instructions? For developers, programmers? So they themselves know how to write code and they don’t need plugins! Is it not possible to write: step 1 enter the following script into the file function.php, step 2 enter the script in the file … step 3, enter the script in a file …??? That’s the second step I don’t understand?
