How To Choose

If you are a professional, then try to target those forums that claim to be for professionals.

These forums are also open to non-professionals (which can lead to getting you some business), but brace yourself for some stupid questions and some name calling if any poster has a chip on their shoulder. Although some flame wars are inevitable, try to avoid lawn and landscape forums where almost every thread includes a flame war of some kind. You don’t need the stress.
Most importantly, you need to see how active the lawn and landscape online forum writemypaper4me is. There should be many recent posts, preferably in the last week. If you see that the last post was over a month ago, then this is a big neon flashing sign that hardly anyone bothers to check out this forum. You are better off leaving it for a more active one. It’s a better use of your time.
Take time to read the FAQ page to see what topics are and aren’t allowed. There also may be rules on whether you can put links your website on the signature of your posts are not. If you can, do so, as this is great free advertising. You already know that your target audience is interested in what you have and will be more likely to go check out your website than even if you advertised in other ways.
Choose a free lawn and landscape online forum. There really is no reason to have to pay to be on a forum. You do want to be sure that you have updated your computer security software before you go checking out anything online, let alone lawn and landscape forums.
