There’s no general answer – it depends on your business, your products or services, and your target audience. However, there are some general tips that can help you get started with promoting your business on Instagram for free.
First, make sure that your profile is complete and up-to-date. Include a link to your website or blog in the bio section, and use relevant keywords in your profile so that people can find you easily.
Second, start posting high-quality photos and videos that showcase what you do. Use hashtags to reach a wider audience, and tag other users in your posts when relevant.
Third, take advantage of Instagram Stories by sharing behind-the-scenes content, exclusive offers, or helpful tips related to your business. Stories are a great way to engage with potential customers who might not be following you yet.
Finally, be active and responsive in the comments section of other users’ posts. Engage with others in a genuine way – don’t just try to sell them something! – and build relationships with potential customers and influencers who could help promote your business down the line.

Tips to Get More Followers on Instagram
It’s no secret that posting useful, relevant content is essential to attracting more followers on any social media platform – and that includes Instagram.
If you’re not sure what kinds of posts will be most useful to your target audience, consider surveying them directly or taking a look at what similar accounts in your industry are sharing. Once you have a good understanding of the types of content your audience is interested in, it’s time to start creating!
Here are a few tips for creating useful posts that will help you attract more followers on Instagram: * Share behind-the-scenes photos and videos: People love getting a sneak peek into how businesses operate, so don’t be afraid to share some behind-the-scenes photos and videos from time to time. Just make sure the content is still relevant and interesting to your target audience. * Showcase user-generated content: User-generated content (UGC) is always a hit on social media, so why not showcase some of the great things your fans are saying about your business or products? You can even repost UGC directly on to your Instagram account with permission from the original creator. Just be sure to credit them when you do! * Offer exclusive discounts and deals: Everyone loves a good deal, so offering exclusive discounts and deals through your Instagram account is a great way to attract new followers (and keep existing ones coming back for more). Just be sure that the offers are truly exclusive – meaning they can only be redeemed through your account – otherwise you risk devaluing your brand.
Post captivating, high-quality images

Make sure to use hashtags:
Another great way to do free marketing on Instagram is by using hashtags. This allows people to find your content more easily, and also helps you connect with others who are interested in similar topics. Try to use a mix of popular and niche hashtags for the best results.
Post regularly:
To really make an impact on Instagram, it’s important that you post regularly. This will keep people coming back for more, and also ensure that your content is seen by as many people as possible. Try to post at least once a day, but more often if possible.
Post at the right time

Posting at the right time is crucial for getting your content seen by the largest possible audience. The best times to post on Instagram are:
– during weekday mornings and evenings (especially around 9 a m and 6pm) – on weekends (especially around noon)
Of course, these are general guidelines – you’ll need to experiment to see what works best for you and your audience. But if you want to maximize your chances of being seen, these are the times to post.
Ask questions in your posts

If you want to do free marketing on Instagram, one of the best ways to do so is to ask questions in your posts. This will get people talking and engaged with your content, and it can also help you get valuable feedback from your followers. Just make sure that you’re asking relevant questions that will actually be useful to you and your business.
Get creative with your captions
Come up with something that will make people want to read your caption, and make sure it is relevant to the photo. If you can be funny, or even better – relatable, people will be more likely to engage with your content. Also, try to avoid using too many hashtags – no one wants to see a caption full of them!
Regarding marketing on Instagram, one of the most important things you can do is come up with creative and interesting captions for your photos. This is because your caption is what will get people interested in reading your content, and if it is not interesting or relevant then they are likely to just scroll past it.
So how can you make sure that your captions are both creative and interesting? Well, one way is by being relatable. People love seeing content that they can relate to on some level, so if you can find a way to tap into that then you’ll be on to a winner. Another way to make sure your captions are interesting is by being funny – everyone loves a good laugh, so if you can crack a few jokes then people will definitely enjoy reading your content more.
Of course, it’s important not to over do things when it comes to hashtags – no one wants to see a caption full of them! However, using a few strategically placed hashtags can actually be beneficial as they help promote your content and reach new audiences. Just don’t go overboard….
Always use #hashtags
If you’re looking to do free marketing on Instagram, one of the best things you can do is use hashtags. Hashtags are a great way to get your content seen by more people, and they can help you connect with other users who are interested in the same thing.
When you use a hashtag, be sure to include it in your caption so that people can easily find it. You can also search for popular hashtags and see what others are using. If you find a popular hashtag that isn’t being used by many people, consider using it yourself to get more exposure.
Another great tip for doing free marketing on Instagram is to post often. The more often you post, the more likely people are to see your content. If you only post once in awhile, people may forget about you and move on to someone else who is posting more frequently.
Finally, always respond to comments and messages left by others. This shows that you’re active on the platform and that you’re interested in engaging with your audience. By responding to comments and messages, you’re more likely to build relationships with other users which can lead to more followers and eventually customers or clients!
