SOCIAL MEDIA & DIGITAL MARKETING
Instagram Search in 2026 functions like a search engine. Users type queries into the Instagram search bar and expect relevant results. The accounts and posts that appear at the top of those results are not there by chance. They are there because their profile, captions, hashtags, and alt text are optimised for the specific terms their ideal audience searches for. This is Instagram SEO, and it is one of the most underused growth strategies for business accounts in the UK.
Instagram SEO is the process of optimising your account and content so they rank highly in Instagram's internal search results. When a user searches for AI software London or bespoke software development or Instagram growth tips UK, Instagram serves results based on relevance signals across multiple content fields.
For business accounts, Instagram SEO matters because it creates a discovery channel independent of the main feed algorithm. Users who find your account through search have already demonstrated intent: they searched for a topic you cover. They are more likely to follow, engage, and convert than users who happen to see a Reel in their feed.
Instagram's search algorithm gives significant weight to username and display name when matching search queries. If your display name includes the keywords your ideal customer searches for, you will appear in those search results. A username of @softomatesolutions with a display name of Softomate Solutions | AI Software London will appear for searches including AI software London in a way that a display name of just Softomate Solutions will not.
Update your display name to include your primary keyword alongside your business name. This is the fastest single change you can make to improve Instagram SEO.
Instagram indexes the text in your bio for search. Include your primary keyword phrase naturally in your bio. For a London software agency: include software development London or AI automation London in the first two lines of your bio where the keyword density is highest for Instagram's indexing.
Instagram reads caption text to understand the topic of each post and match it with relevant search queries. Write captions using the exact phrases your ideal customers search for. If your target audience searches for how to automate customer service with AI, use that phrase or close variants naturally in your captions.
This does not mean keyword stuffing. A caption that naturally discusses the topic will include relevant keywords without forcing them. Write about the topic in the language your audience uses and the keywords will occur naturally.
Hashtags remain a search ranking signal in 2026, though their weight has decreased relative to caption text and profile fields. Use three to five specific, relevant hashtags per post. Instagram indexes hashtag pages and surfaces content from those pages in search results for related queries.
Choose hashtags that are specific enough to reach a relevant audience but not so niche that almost nobody searches for them. A London marketing agency using only #marketing is invisible among millions of posts. Using #digitalmarketingLondon or #londonmarketingagency reaches a smaller but far more relevant pool of potential followers.
Instagram allows you to add alt text to images, and this alt text is indexed by Instagram's search algorithm. Most business accounts never add alt text. The ones that do have an advantage in Instagram Search for the keywords included in their alt text.
To add alt text on Instagram: after selecting your image and before posting, tap Advanced Settings at the bottom of the caption screen, then tap Write Alt Text. Write a natural description of the image that includes your primary keyword.

Instagram's search algorithm, like Google's, gives preference to accounts with high engagement rates and established authority in a niche. An account that consistently produces high-engagement content on AI automation topics will rank higher for AI automation searches than a new account posting about the same topic. This is the long-term Instagram SEO factor: building account authority through consistent, high-engagement content over time.
Effective Instagram SEO starts with knowing what your ideal customers actually search for on Instagram. The research process is different from Google keyword research but the principle is the same.
Spend 30 minutes auditing these five elements of your current account before making changes.
Yes. Accounts optimised for Instagram Search receive a consistent stream of new follower requests from users who found them through search. Unlike algorithm-driven discovery, search-driven discovery is intent-based: the user was already looking for what you offer. These followers typically have higher engagement rates and higher commercial value than followers gained through viral reach alone.
Profile and display name optimisation can show results within days as Instagram re-indexes your profile. Caption and alt text optimisation accumulates over weeks as new optimised content builds up. Account authority as an Instagram SEO factor builds over months. Start with the profile and display name changes first as they have the fastest impact.
Not always. Instagram users search with shorter, more conversational queries than Google users. A Google searcher might search bespoke software development company London cost. An Instagram searcher searches software development London or London tech company. Research Instagram-specific search behaviour rather than assuming your Google SEO keywords transfer directly.
