Guest posting fees? Do you guys have a tiered system?

Without getting into the pro's and con's of Guest Posting: I'm doing it, but the bit I am struggling with is when the webmaster replies positively but then pushes back on me how much I am willing to charge.

Hardly surprising but the profile of person acting as per above has a DA of around 10 - 25-ish but the blogs are very niche-relevant hence why I am interesting in these types if links

So, my question:

Do you do something like:

• USD 50 - Link insertion for a DA 20 (i.e. "your site" perhaps shown them a screenshot of AHRefs)
• USD 120 - Blog Guest Post (500 word) etc

Etc etc

Is that how you'd reply - is there a fee you'd charge?

Thanks for all thoughts/experience - comments
