I do like Instagram and I have a lot of interaction with it. I post the same times everyday and I have found you can use quite a few hashtags with Instagram, as many as 30 where other platforms work better with a few.
Although I get interaction and followers you cannot add links so I request followers to paste the URL to view an article on my website.
i have found I get a lot of engagement in Instagram however it is very visual so photos and 60 second videos rule here.
If you can edit a photo or put a leaflet together in Jpeg then you can still advertise.
it is estimated to have 600 million users with popular ages to be 18-29 like Twitter this will go up in age as time goes on.
Once you get the hang of Instagram you can build followers and forge business relationships in nearly every industry as it is easy to use # to share your branding.
What is your opinion as far as FB goes, a business page, or do you use your personal account?
