Whether searching for a product or determining what others are buying, entering a keyword is the first step. Select the ebay longtail keywords from the list that are most relevant and download them. By typing the results into Ebay, you will quickly see if there is a demand for your product. As a buyer you will get the most relevant products to your search.
Ahrefs is a worthy tool, although I feel they should give new users a free trial instead of the $7 for 7 days trial, which is hardly enough trial period to adequately track a competitor’s website. For individuals/freelancers in the SEO digital space, the subscription pricing is quite high when you’re just starting, but once your clients start to see the benefits, it will be worth it as you get more business. Otherwise, there’s little I found to dislike about Ahrefs.
I've used a couple of SEO software programs over the last 4 years. Moz, Serpstat, SEM Rush and now Ahrefs. Since the bulk of my focus is actually building links, I think Ahrefs has the most reliable results. For example, if you checked the backlink profile of 10-20 websites on Ahrefs and compared to another SEO software provider, I bet that you would average at least 10-15% more results with Ahrefs. That can be a lot more opportunities! Their keyword phrase tracker seems to work pretty quickly and seems to be accurate.
What would be the purpose of/reason for moving back to a different url? If its been a few years, I’d leave it alone unless you watched everything decline since moving to the main url. Moving the forum to a new url now would probably be a bit chaotic, not only for your main url but for the forum itself…. 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…
