You may well be right about SEO and what have you.
I searched for “Keyboard Maestro firefox” in DDG, and it found How to Get URL of FireFox Current Document? as the third possibility, but in Google, it did not find anything.
It may be due to the relative youth of the forum - its only been around for a short while (less than a year). Google (last I hear anyway) places value of links to the forum from other places and there probably is not a lot of them at this point.
Maybe I should add some google advertising to the site, I’m sure that would improve the rankings!
It may also be that there have been a lot of different people writing about Keyboard Maestro over the years, and so there is information on a lot of different sites for Google to choose form.
I agree it would be nice if the forum showed up closer to the top, but I don’t currently have any plans to try to SEO for Google - Google usually figures out the good stuff in its own way eventually.
