Where am I?
In GrowthSpot you can ask and answer questions and share your experience with others!
If this is for personal use, I would ask myself these two questions
1 - Which channel is my target audience most active on?
2 - Which channel do I like using the most?
If my target audience is on Instagram and I also love taking picture and videos then that's the platform I should start with.
If this is for business use, I would also ask
3 - Which channels my competitor is the getting most engagement on?
hope this helps
