Mass article creators like Kontent Machine are great for your 2nd or 3rd tier links but that still leaves you needing a solution for your tier 1 powerhouse links. Try as I might, I never been able to extract an article I would feel good using on Tier 1 with Kontent Machine. Don’t get me wrong, I love Kontent Machine and it saves me hours every day, but using it for Tier 1 content would be website suicide.
Spin Rewriter integrates with almost any SEO software. This allows you to post high quality articles quickly and easily. The only drawback is that you only get something like 300 API requests every 24 hours. You can quickly burn through this if you’re doing multiple campaigns. The developer does not currently offer a plan for heavy API users but maybe they will in the future.
