Look no further, our sponsor this week is RhinoRank.io, fun fact: I used to resell their services. We don’t anymore, but that’s a story for another time.

They were kind enough to give our readers 10% off with the coupon code INDEXSY10OFF. They do niche edits AND guest posts, with a huge team fully based in the UK. Great service, I used to Karen them all the time...

Questions sponsors ask

How much does it cost?

Rates are on the booking page. Multi-issue runs get better rates.

Who writes the ad?

We do, with your input. You approve it before it sends.

How fast can I run?

If your category is free, within the week. Popular dates book out.

Can I track results?

Yes. Use any UTM or tracking link you like.

What if my product isn’t a fit?

We refund you in full rather than send it. Protecting the list is what keeps the 41.9% open rate.
