This seems to work pretty well!
Over the last 3 months the number of daily vid views went from 1000 to around 4000 now.
This is impressive and even though it does not sound like much compared with other top video channels, it is a lot if I consider the fact that my site has been getting overall 700 visits/day average over the last 2 years.
In comparison, posting videos has been a super effective way to gain exposure and impact fast.
Yes! It requires focus and high quality content, but it does work!
Overall, that's an action line which gave the highest results.
A quick note: only 25% of my vids have a promotional edge to them - there is still solid content and information in all of them even the promotional ones!
