Low Media Spend Contribution in Robyn Model

[Samay-3937]

I'm getting low media spend contribution in my analysis, while I usually see high contributions for the intercept and trend components. Can someone help explain why this is happening? Is there something I might be overlooking or a specific parameter in Robyn that controls this behavior?

Any insights would be greatly appreciated!

What do you mean by "low" media spend contribution? The media contribution greater than 10% is unlikely. Also, you could check two important things: 1) The ratio between media spend and revenue 2) The spend share of each media channel. If there is one channel with a small share, likely that channel will not contribute.
