Instagram accounts with inspirational quotes

The only thing I can think of outside of clear monetisation towards a product or LP is that the account holder is hoping to use the fact there is a large following / engagement as a selling point for selling sponsored/paid posts.

They might be selling Tshirts with inspirational quotes.

I'm fairly new to social media marketing, but the quotes provided run the gamut from inspirational to humorous to cat videos and variety of other warm and fuzzy gifs and cartoons. Plenty of this on Facebook, Twitter as well.

Social Media is supposed to be, well, 'social,' and too many hard sales pitches are considered to be somewhat of a turn-off. If you're on Instagram, say, for marketing, then Social Media marketing experts recommend sharing engaging visuals with occasional soft-selling.

The main purpose of all of this is for people to like you, be comfortable with you, trust you, look forward to your posts and, eventually, maybe buy from you.

It should be pointed out that there are some similarities here with Forum etiquette. The main focus is to help and be helped. Direct selling is not permitted except for maybe your Signature or paid advertising.

I don't find a lot of inspirational quote templates here, but you can certainly find a lot of encouragement. A different culture, and it would probably be a stretch to call this forum social media, but they both share some of the same values.

I know of two persons who just do it for fun they have around 20-30k subs but they don't flog anything they just like to have inspirational quotes.

As was said already most probably they are selling promotional post to other people , who are interested in purchase.

I saw few people do that and it is great way to monetize your account if you know what you are doing and therefore you are doing it right . Instagram of course do not like this kind of a promotion , therefore you can be banned.

some people just like to post pics and quotes.

I think the large base followers Instagram accounts you've discovered all from sellers of Fiverr. When they get orders they just use the account to deliver the work. Since those account don't have any business purpose at all.
