Identifying the Best Topics/Keywords for PLR Content
I have a website that does okay with Adsense (about $30 to 60 per month with no updates in the past year), but I'd like to develop my own information products so I'm not relying solely on rankings for income.
I'd love to put together PLR packages with articles, reports, e-books, and infographics, but I'm a bit rusty on finding good keywords/niches. Can anyone recommend a longtail keyword research tool?
