Five Lead Generation Tips for Instagram
Show some behind-the-scenes  photos of your company/business– Sharing staff photos and company events gives followers the inside scoop about your company. It also gives you a chance to introduce your staff to the general public, and show off the people that use their talent to enhance your brand. It puts human faces on a brand that your followers would otherwise be unable to connect with. In a way, this humanizes your brand and makes it more accessible to your followers.
Showcase your CSR initiatives – Another way to humanize your brand is to take pictures of your company engaging in Corporate Social Responsibility (CSR) initiatives. Showcase events where your company is engaging in the social good of the community. Does your company volunteer at a soup kitchen every year? Post photos of your Chief Marketing Office serving food to the homeless. Let the world see your humanity.
Show off your products – In addition to sharing photos of staff members and CSR events, you should definitely use Instagram as a platform for showing off your actual products. After all, the whole reason you're using Instagram in the first place is to get potential customers to become paying customers. You'd be doing yourself a great disservice if you didn't leverage Instagram as a platform for showcasing products to your followers.
Engage with other brands on Instagram – While it isn't exactly second nature to engage with other brands on Instagram, it is definitely possible. The best way to do this is to like and comment on other company's photos. This goes a long way to demonstrate that you're trying to invest in creating an Instagram community. It may even give you some valuable leads in the process.
Personalize your hashtags – Finally, don't underestimate the power of personalized Instagram hashtags. However, if you do go down the hashtag road, it's important to understand the nature of hashtags. They're only there to make your brand or profile more visible through search. Do not use arbitrary phrases just because they are humorous or entertaining. Unless they are built around searchable keywords, they will not help your lead generation strategy at all.

Instagram's overrun with ghost followers, your dream leads are just pixel dust - ham-fisted hashtags spam, ego-boosting Reels lie about traffic, lazy DM blasts annoy peeps, sorry ads retarget rejects, ditch the delusion, funnel fails because you A/B'd nothing and call it 'optimization'.
