Use the words your customers type. Instagram matches searches against usernames, bios, captions, hashtags and places; YouTube weighs titles, descriptions and the video itself. Write each in plain search language, and since July 2025 public business posts on Instagram can surface in Google too.
You get found in social search the same way you get found on Google: by using the words people actually type. Instagram says it matches a search against usernames, bios, captions, hashtags and places, and YouTube says it weighs how well a video's title, tags, description and content match the query. So name your profile plainly, say what you do and where in your bio, and title every reel or Short with the question it answers.
Google has acknowledged the habit itself. In 2022 one of its senior vice presidents said almost 40% of young people looking for somewhere to have lunch went to TikTok or Instagram, not Maps or Search, and Google later said the figure came from a survey of US users aged 18 to 24. India blocked TikTok in June 2020, so here the obvious places to be found are Instagram and YouTube, whose ad reach in India DataReportal put at 481 million and 500 million people in late 2025.

How Instagram search decides what to show
Instagram's own explainer, published in 2021 and still on its site, lists three kinds of signal, in order of importance. The words someone types come first, matched against usernames, bios, captions, hashtags and places. Next comes the searcher's activity, such as accounts they follow and posts they have viewed. When many results match, popularity signals such as clicks, likes, shares and follows help decide the order.
Its advice to accounts follows from that: use a handle and profile name related to what you do, put keywords that describe you in your bio, share your location in the bio if you serve a local area, and put keywords and hashtags in the caption rather than the comments.
Hashtags are shrinking in importance. In December 2025 Instagram began gradually limiting posts and reels to five hashtags, and its head, Adam Mosseri, said during 2025 that hashtags do not improve visibility, though they help tell people what a post is about. Write the caption as a sentence a customer would recognise, then add up to five specific tags.
The text you enter in the search bar is by far the most important signal for Search.
02
How YouTube search decides
YouTube names three elements: relevance, engagement and quality. Relevance looks at how well the title, tags, description and video content match the search. Engagement includes how long people watch a particular video after a particular search. Quality means channels that show expertise, authoritativeness and trustworthiness on a topic. YouTube also says it does not accept payment for better placement in organic search results, and that results can be personalised by search and watch history, so searching for yourself on your own phone is a poor test.
Tags matter less than most people think. YouTube says they play a minimal role in discovery and are mainly useful when your topic is commonly misspelled, and that adding too many tags to a description breaks its spam policies. Captions are worth the effort for viewers either way: YouTube generates automatic captions, warns that their quality varies, and asks creators to review and correct them.
03
Write for the search box
The fields differ by app, but the job is the same: put the words a customer would type where each app looks for them.
| Signal | YouTube | |
|---|---|---|
| Text matched to the search | Usernames, bios, captions, hashtags and places | Title, tags, description and video content |
| Engagement that helps | Clicks, likes, shares and follows, when many results match | Watch time for a video after a particular search |
| Hashtags or tags | Up to five per post; they say what a post is about | A minimal role, mainly for common misspellings |
In practice, state the question in the first few seconds, say it out loud for viewers with sound and put it on screen for those without, then repeat the same words in the first line of the caption or in the YouTube title and description. A hypothetical Kochi bakery would title a reel "Eggless birthday cakes in Kochi: how much, and how soon?" rather than "Weekend vibes". Then answer it properly, because the engagement both apps weigh comes from people who stay to watch.
Use the language your customers search in. If they type Malayalam words, or Malayalam in English letters, put those words in the caption and on screen as well, alongside the English terms, and say your town or neighbourhood by name.
04
Your posts now show up in Google too
Since 10 July 2025, public photos, videos and reels from professional Instagram accounts, meaning business and creator accounts held by adults, can be indexed by Google and other search engines, for posts going back to 1 January 2020. Once an account qualifies, all its public photos and videos become eligible. You can opt out in privacy settings, though profile details such as your username and bio may still appear in search engines.
That turns a well-captioned reel into a small web page for your business. The plain caption that helps Instagram's search also gives Google something to match. If you still run your business from a personal account, this is a good reason to switch to a professional one.
05
Measure search, not just likes
YouTube shows you exactly what people searched for. In YouTube Analytics, the Reach tab's traffic source card for YouTube search lists the search terms that led viewers to each video. Check it monthly and make your next videos about the terms already bringing you viewers.
On Instagram, look at which posts lead to follows and messages rather than likes alone, and ask every new enquiry how they found you. A customer who says they searched for you on Instagram is the result that counts, and logging the answer in your CRM shows you which posts earn it.
06
The crossover routine
- Start from your website FAQ and your sales chats, and list the 20 questions customers ask most.
- One question per video. State it in the first few seconds and use the same words in the caption, title and description.
- Fix your profile fields: a plain handle and name, and a bio that says what you do and where, in the words customers use.
- Use five hashtags or fewer on Instagram and few or no tags on YouTube. Specific beats generic.
- Publish each answer in both apps, as a reel and a Short, then check YouTube's search terms every month.
- Keep your Instagram account public and professional so its posts can appear in Google as well.
Search-led content compounds the way SEO does, because a clear answer keeps getting found long after it is posted. If you would like help turning your FAQ into a content calendar, that is how our social media work starts.
