Instagram is a wonderful way for a Instagram web development to connect with clients and future clients they can show parts of their services.
They can show pricing sheets thus they can change their marketing according to the client they are trying to grab.
If you use more then one account a web developer can target clients at the level they need. If a big client keeps getting information about building Word Press sites and they have a major site that needs updating for credit customers and security for enterprise the communication from a developer needs to reflect that. It’s not about the size of the web developer’s team. It’s about getting them to see you as capable while you are still working with quick turn around projects. And you really do not want a big account seeing you take thousand from some projects and asking tens of thousands for bigger projects. They might try to low-ball you.
