Dang, this is great. Really great.
HubSpot, for those of you who don't know, is probably the dominant platform in "inbound marketing." They seem to think they invented inbound marketing, although I think there are seed catalogs from the 19th century that were there first. Leaving that aside..
Ms. Fitton is a smart, energetic and no-BS speaker. (I particularly enjoy the fact that she uses real-world terms like BS - I'm prone to do that on stage myself.)
At 3:18 she has a slide that says
"Solve problems or share resources, don't shill. What marketing content will your customers THANK you for?"
I think there's an insidious notion about marketing content, fostered by search and SEO - namely, that people are interested in originality.
They're interested in solving problems or understanding things.
IF you have an original solution - not just re-statement of an existing solution - by all means share it.
If you can share an existing solution and save your energy for solving something else - instead of restating so Google will like you - then please do that.
