What I have noticed is Instagram SEO is now far more important than before. Now as Instagram has its own in-app search feature, the optimised post/reels definitely comes in search results. Also, AI overview shows results in the form of reels suggestion from credible sites of influencers. Moreover, unlike normal posts that get no results on Instagram, SEO-optimised posts have higher chances of coming up in feed and get engagement. So both for short-term results and long term reach, Instagram SEO is important and should not be avoided.
