Louis, I'd like to ask about some advice about promotion google ext.

How did you do marketing part of your Google Extention?
what channels of promotion better and worst

Maybe a general approach to promoting this type of saas product.
I'll appreciate any suggestions for this side.

P/s I'm going to run small google ext either and except promotion the landing page/main site I don't know what could be useful more without large amount money for marketing.
