The text fields the algorithm reads
Instagram's search matches queries against the name, username, bio and caption text first, then weighs engagement and relevance signals. That makes the name field the single most valuable keyword placement on the platform — searchable, weighted, and almost universally wasted on a first name or a brand word. Bios that state what the business does and where, in the words customers use, surface for those searches; bios written as slogans don't.
Captions, alt text and on-screen text
Captions are indexed. Descriptive captions — the dish, the treatment, the neighborhood, the occasion — match searches that clever captions never will. Alt text, which most accounts ignore, is read for search and can be written deliberately. On-screen text in reels is increasingly parsed as well. None of this replaces good creative; it makes good creative findable.
Location and local discovery
Location tags and a consistent city in the bio feed the local discovery that younger buyers use — best brunch in South Tampa, searched inside the app. Businesses that tag locations consistently and name their neighborhood appear in searches the feed alone would never reach.
The Google connection
Public Instagram profiles and posts are indexed by Google, and the profile is one of the entity signals AI systems weigh. A business whose Instagram name, handle and bio match its Google Business Profile name, category and city reinforces its identity everywhere at once. Mismatches — a playful handle, a different name, no city — do the opposite.
What it isn't
Instagram SEO is not hashtag stuffing, and it doesn't replace content that people actually want. The ranking system still rewards engagement. The point is that the text layer most accounts leave empty is a search surface — and filling it costs nothing.
