Estimated value
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
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.

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?
