Here are a good topics about the cross-posting SEO impact:

I have a moderately small but content-heavy blog post and was thinking about using the Cross Posting plugin for SEO purposes only as I thought it may have some impact. However, I am not really sure of what impact if any it will have at all so at the same time I am scared of wasting my not-so-precious time and moderately precious money.

Any positive educated feedback is appreciated.
