Do Instagram Keywords Work When You Have Low Engagement?

Summary: Instagram keywords help new people find your posts days, weeks, months, and some cases years after it’s originally published. But what if no one typical engages with your content? Can Instagram keywords increase reach when you don’t get engagement on your posts? The short answer is yes, with one big caveat. This article explains how Instagram search works and how to increase Instagram engagement with keywords.

About the Author: Hi I’m Cyndi, writer, brand storyteller, content strategist, and owner of StoryCraft. Following traditional digital marketing tactics, I grew my Instagram to 65K—and promptly burnt out. Eleven months after I quit social media sales increased 55 %. Today, I help business owners bypass pressure-filled tactics to build sustainable businesses that moves their mission forward in a way that feels good.


“I don’t get a lot of engagement on my posts. Can Instagram keywords still help my content rank in search results and the on the Explore page?”

Instagram is an engagement-driven platform. 

A popularity contest of sorts that adding keywords shortcuts. 

It’s true: having higher engagement increases your chances of ranking in the top search results on Instagram.   

Instagram’s search system uses both keywords as a filter (to determine if your post is relevant) and engagement as a ranking factor (to decide where to position it among all matching results). 

Posts with higher shares, saves, and watch time get pushed to the top of the search tab because those interactions tell the algorithm it’s high content quality more people would enjoy.

That is why we put time and effort into headlines, storytelling, and sharp messaging. 

However, it’s Instagram SEO that allows posts with low-or-no initial engagement to get discovered by new people who want to hear with what you’re saying.


How Instagram Keywords When You Have Low Engagement

1. Relevant, specific keywords

Pair high traffic keywords ("fitness tips") with hyper specific long-tail keywords (e.g., "at home lower back mobility for beginners").

For broad search terms like "fitness tips," high-engagement accounts occupy the top spots.

However, if you target specific, long-tail keywords (e.g., "at home lower back mobility for beginners"), there are far fewer competing posts.

Your post can land in the top search results purely based on specific text relevance on your slides, caption, alt text, and bio. 

2. AI topic categorization

When you optimize a post with keywords, Instagram's AI indexes and categorizes your account. Once the platform understands your niche, it puts your post into a "testing pool," showing it to a small group of non-followers searching for or browsing that specific topic so you can reach people who are interested but don’t know you exist yet.

Being selected for "testing pool" process doesn't require high follower counts or existing engagement—it's triggered solely by relevance.

This is why some accounts suddenly blow up overnight after years of low engagement. SEO and keyword optimization qualify your content for these test pools and keyword searches, but strong hooks, storytelling, and messaging determine whether it will get engagement, which then factors into where your content ranks in search.

It's why my I teach my clients and students focus on engaging people through storytelling content that uses keywords. See examples of storytelling content that uses Instagram keywords to increase reach.

3. Evergreen discovery

Posts without keywords rely on your existing followers engaging within the first few hours for your content to get pushed out.

Search operates differently: search-optimized posts remain indexed indefinitely.

A post with zero likes today can sit in search results and slowly collect views, saves, and interactions from people searching for that topic weeks or months later.

In addition to the text on your slides, keywords in your caption and alt text make this indexing process faster and more accurate.

SEO optimized posts are also discoverable on Google and through AI recommendations.


How Do I Add Keywords In Instagram Posts?

The great thing about using keywords on Instagram is that you don’t need to pay for a third party tool or a degree in search engine optimization to make it work.

Using Instagram’s built-in search bar you can find short-and-long tail keywords folks are searching for when they’re interested in the topics you discuss.

Here’s a guide on how to find keywords and where to put them to increase engagement and reach:

The beauty of this strategy is its longevity.

When you optimize your profile, captions, and alt text, you aren’t just fighting for a "like" today—you are building a searchable library that works for you while you live life offline.
