Google’s bots crawl your site to determine its quality, and correct technical on page optimization is one of the main signals used. When you optimize your page based on the recommendations of the website analyzer, you can increase your organic traffic, improve ranking positions, and stay competitive against other sites ranking for your target keywords.
Lite allows you to have a 7 day trial for $7. After the trial ends, it costs $99 per month or $990 per year. This plan allows you to track up to 5 projects (websites) and track 500 keywords per project. You can search 25 batches of keywords per day, but you can search up to 10,000 keywords per batch.

It depends on the size of your operation, but I think you could get just as much value out of the Mangools Suite. This is the group in charge of KWFinder. But you can also take advantage of their SERP watcher and LinkMiner, and SiteProfiler features since you have an established business. They aren't quite as powerful as Ahrefs, but they get you 90% of the way for about 50% of the cost.
Depending on the plan, you are only allowed up to 100 domain searches a day. If you purchase their top tier plan you only get double of that. Sometimes it can take you several days to do certain types of research. This can start to get a little bothersome as we work with several clients and all of them need to use this software to make sure everyone is getting the best work that we have to offer.

Only reason I could imagine myself moving the forum in this scenario would be if all those links were really awful and unrelated to the url it currently sits on…
