With millions of active members on the Instagram platform, you have a chance of getting many Instagram likes and comments if you reach out to a good number of other members here. All users here form a community that you are part of it hence let the community help you increase your engagements. It is a give and take approach as you help each other. It is always good to spare some time to comment and like a friend’s post. They will want to reciprocate the same and comment on your too. It is proof to your followers that you are human and not a robot behind that account they follow. If you never acknowledge their post, automatically they won’t reciprocate the simple gesture. They don’t necessarily need to be your friends but rather random people on the platform already. Opt for those with many following than followers to get an advantage of the numbers. You are likely to get many Instagram likes and followers at the same time if the account owners notice your activity to their photos and videos.
