What is Instagram SEO?
Instagram SEO is optimizing the profile and posts for the network’s own search, which now looks for words in captions, alt text, the profile name and the bio, not only in hashtags and usernames. Google also indexes public profiles and posts. In practice: put the word that describes the business in the name field, write captions that state the subject directly, use descriptive alt text and keep hashtags specific. It does not replace good content; it makes good content findable by whoever searches.
