📊 Did You Know? 46% of Gen Z and 35% of Millennials now search on Instagram or TikTok instead of Google. And 49% of Americans have used TikTok as a search tool, up from 41% just two years ago. |
This article will show you exactly how to do it. Simple steps, plain language, no complicated terms.
What Is Social Media SEO?
Social media SEO just means making your posts easier to find when someone searches.
Think about how Google works. You type something, and it shows you the most useful results. Instagram and TikTok do the same thing now. You type a topic, and they show you posts, videos, and accounts related to that topic.
So if you post about food, fitness, or fashion, and you want new people to find you, you need your posts to show up when they search for those things.
And here's the big news: since July 2025, Google also shows Instagram posts in its search results. So a good Instagram post can now show up on Google too, not just inside the app.
💡 Simple Way to Think About It Social media SEO = writing your posts in a way that helps the right people find them when they search. |
How to Make Your Instagram Posts Searchable
Fix Your Profile First
When someone searches for a topic on Instagram, it looks at your name and bio first. So these need to have words that people actually search for.
• Your display name should include what you do, not just your name. Example: 'Riya Sharma | Skincare Tips' works better than just 'Riya Sharma'
• Your bio should say clearly what you offer. Keep it simple. 'I share easy home workouts for busy people' is better than 'fitness enthusiast, lover of all things wellness'
• Use the same username on all platforms if you can, it makes you easier to find everywhere
Your bio is only 150 characters. Every word counts. Write it like you're explaining yourself to a stranger in one sentence.
Write Captions That Sound Like a Search
Instagram reads your captions and uses them to figure out what your post is about. So write captions the way real people search.
Instead of writing 'obsessed with this look, write something like 'easy summer outfit ideas for women under 500 rupees.' That second one is what people actually type.
• Use simple, everyday words in your captions
• Put your main topic in the first line, don't bury it at the end
• Think: what would someone type if they were looking for this post.
Use the Right Hashtags
Hashtags help Instagram understand what your post is about. But you don't need 30 of them. 3 to 5 good ones is enough.
• Use specific hashtags, not just big ones. #dryskintips reaches the right people better than #skincare
• Don't use random trending tags just because they're popular — they need to match your post
• Think of hashtags as labels, not just decoration
Add Alt Text to Every Post
Alt text is a short description you write for your photo or video. Most people skip it. You shouldn't.
It tells Instagram and Google what is in your image. It takes 10 seconds to write, and it genuinely helps your post show up in search.
Just describe what's in the photo, and include your topic naturally. Example: 'homemade chocolate cake recipe with fresh strawberries on top.’
How to Make Your TikTok Videos Show Up in Search
TikTok is now one of the biggest search tools for young people. Many Gen Z users go to TikTok before they go to Google. So if you're on TikTok, making your videos searchable is very important.
Say Your Topic Out Loud in the Video
TikTok listens to what you say in your videos and turns it into text. Then it uses that text to decide what your video is about.
So if your video is about budget travel in Goa, say the words 'budget travel in Goa' in the first few seconds. TikTok picks it up and shows your video to people searching for that. You don't need to sound robotic. Just say your topic clearly, like you're explaining it to a friend.
Put Text on Your Video Screen
TikTok also reads the words that appear on screen, like subtitles or text overlays. So these are another way to help your video show up in search.
• Add a short text at the top of your video that says what the video is about
• Use subtitles; they help people watch without sound, and they help TikTok understand your content
• Keep the text clear and easy to read: big font, simple words
Write Your Caption Like a Search Title
Your TikTok caption is one of the most important things for search. Write it like you're answering a question someone typed.
• Lead with your main topic, example: 'How to study for exams without feeling stressed.'
• Don't start with emojis or vague phrases like 'guys, this is crazy'; that doesn't help search
• TikTok now lets you add a separate video title in some places; use it like a heading and keep it short and clear
Keep People Watching Till the End
TikTok's biggest ranking factor is how many people watch your video all the way through. The more people who finish watching, the more TikTok pushes your video to others.
So your first 2–3 seconds need to be really good. Get to the point fast. Don't waste time with long intros. Make people want to keep watching.
Use Specific Hashtags on TikTok
Same rule as Instagram: 3 to 5 hashtags, and make them specific. #dryskintips is better than #skincare. #budgettravelin India is better than #travel.
TikTok's own data shows that specific, niche hashtags help your video reach the right people more than big general ones.
Instagram vs TikTok SEO: What's Different?
What to Optimise | On Instagram | On TikTok |
Your profile | Name + bio with clear keywords | Username + bio with keywords |
Your caption | Write like a search query, first line matters most | Write like a headline, get to the point fast |
Hashtags | 3–5 specific, relevant tags | 3–5 niche tags, skip #fyp only |
Visuals | Add alt text to every photo or video | Put keyword text on screen clearly |
Your voice | Not a factor | Say your topic out loud early in the video |
Google search | Yes, posts can show on Google now | Yes, videos appear in Google results |
Most important signal | Relevance of your content + engagement | How long people watch your video |
Tips That Work on Both Instagram and TikTok
Tip #1: Your Display Name Is a Search Field: Use It
Both apps let people search by name. So don't just put your name. Add what you do next to it. 'Arjun Singh | Travel Tips India will show up when someone searches for travel tips. 'Arjun Singh' alone will not.
Tip #2: Think About What Someone Would Type Before You Post
Before you write your caption or record your video, ask yourself: what would someone type into TikTok or Instagram to find this?
• How-to posts do very well in search: people search for help all the time
• Comparison posts work too: X vs Y' is a very common type of search
• Review and recommendation posts catch people who are about to buy something
Tip #3: Post About the Same Topics Regularly
Both apps learn what your account is about over time. If you post about 3 different topics every week, the app gets confused about who to show your content to.
Pick 2 or 3 topics you care about and stick to them. The more consistent you are, the more the app will start showing your posts to people searching those topics.
Tip #4: Rename Your Video File Before Uploading
This one is small, but it helps. Before you upload a video, rename the file on your phone or computer. Instead of 'VID_20260318.mp4', rename it to something like 'morning-routine-productivity-tips.mp4'. The app reads the file name. It's a small signal, but it's free and takes 5 seconds.

How to Find the Right Keywords for Your Posts?
You don't need to buy any tools for this task. The apps show you what people are searching for, for free.
Use the Search Bar in the App
Open Instagram or TikTok. Type your topic into the search bar. Look at what it suggests. Those suggestions are what real people are typing. Write those words in your captions and hashtags.
Read the Comments on Popular Posts
Find the top posts in your topic. Read the comments. What are people asking? What do they want to know more about? Those questions are what people search for. Create videos or posts that address these questions.
Check TikTok Creative Center
TikTok has a free tool called Creative Center. It shows you which keywords and hashtags are trending right now in your topic area. You can filter by country and topic. Most people don't use it. You should.
Conclusion
People are searching on Instagram and TikTok every single day. They're looking for products, tips, places, recipes, and advice; all of it.
If your posts are not written in a way that helps people find them, those people will find someone else instead.
The good news is it's not hard. You write your captions clearly. You say your topic out loud in your videos. You use a few good hashtags. You add alt text. You think about what your audience is searching for before you post.
Do that every time, and you will reach more people without paying for ads.
FAQ
1. Can my Instagram posts show up on Google?
Yes. Since July 2025, Instagram posts from professional accounts can appear in Google search results. So if someone searches for something on Google and your post matches, it can show up there. Make sure your account is set to Professional and that the search indexing option is turned on.
2. How do I find good keywords for TikTok?
Use TikTok's search bar. Type your topic and look at what it suggests. Those are real searches from real people. You can also use TikTok Creative Center, it's free and shows which keywords are trending in your topic area right now.
3. How many hashtags should I use on Instagram?
3 to 5 is the sweet spot. Use hashtags that are specific to your topic, not just big popular ones. A niche hashtag like #homebakingtips reaches the right people better than something like #baking with millions of posts.
4. Does TikTok really listen to what I say in my video?
Yes. TikTok automatically turns your voice into text using captions. The app reads those words and uses them to decide what your video is about and who to show it to. This is why saying your topic out loud in the first few seconds of the video matters a lot.
5. Can a small account benefit from social media SEO?
Yes, and it might even help small accounts more than big ones. When someone searches for a topic, the app shows the most relevant result, not just the most popular account. A well-written post from a small account can show up above a big account if it matches the search better.
6. How often should I post to get found more on social media?
Posting consistently around the same topics matters more than posting every single day. If you post 3 or 4 times a week on the same topic, the app starts to understand what your account is about. That helps it show your posts to people searching for that topic.
7. Do Reels get found in search more than regular posts on Instagram?
Reels tend to get more reach in general on Instagram. They also show up in Google's video search results, which regular photo posts don't. The same SEO rules apply, good captions, relevant hashtags, alt text, but with Reels you also get to say your keywords out loud, which adds another way for the app to understand your content.
