Caption vs on-screen text: different jobs
The two texts have different readers. Everyone who stops scrolling on your reel sees the text overlay. It drives watch time: Instagram's creator FAQ advises making the first 3 seconds engaging so people don't move on. The text below the video gets read by people who are already interested.
That text has its own job. It explains what happens in the frame and supplies the words people search for. Details go here: ingredients, size, address, booking terms.
| Compare | Text overlay | Text below the reel |
|---|---|---|
| Who sees it | Everyone who stops scrolling | People who open the text or arrive from search |
| When it works | The first seconds of viewing | After viewing and in search |
| Main job | Promise a result and hold attention | Explain, add details, name the search words |
| Length | One short thought | A first sentence, then details and hashtags |
| Cost of overdoing it | Videos made mostly of text get shown less | The key point hides behind “more” |
A common mistake is the same sentence on screen and below the video. People read it twice and learn nothing new. The overlay promises a result, and the text below adds details and search words. Our guide to reel scripts covers how to build the video itself and its first seconds.
The first line: what shows before “more” and how to write it
Below a video, Instagram shows the author's handle and the start of the text, and the rest folds behind “more”. Plan for one short sentence and put everything that matters into it. People decide from that sentence whether to open the full text.
How to write the first line
- Extend the overlay, don't repeat it. The overlay says “Cottage cheese pancakes that hold their shape”, the text below says “The secret is how you drain the cottage cheese”.
- Open with the point. A greeting and a self-introduction eat up the visible part.
- Put the search word near the start. A post about cottage cheese pancakes names them in the first sentence.
- Give a number or a time frame. A number makes the promise concrete: “in 15 minutes”, “three mistakes”, “after 40 washes”.
- Ask a question only when the clip answers it. Otherwise viewers feel tricked and leave.
Five first lines for one reel
Take a home cooking reel: cottage cheese pancakes that don't fall apart in the pan. The same story can open in five ways.
- Result. “These cottage cheese pancakes hold their shape even on high heat.”
- The viewer's mistake. “Stop flipping cottage cheese pancakes with a fork.”
- Number. “Three rules that keep cottage cheese pancakes from falling apart.”
- Relatable scene. “When you flip a pancake and half of it stays in the pan.”
- Search word. “Cottage cheese pancake recipe that holds its shape.”
With the overlay from the example above, the Result line would repeat it, so pick the viewer's mistake or the relatable scene. A trial reel helps test two openings on a new audience.
How to write reel text for search: keywords in the caption
Instagram search reads the text of posts, not just hashtags. Adam Mosseri, head of Instagram, wrote on August 25, 2021 that search matches a query against usernames, bios, captions, hashtags and places. Text overlays are not on that list. The same post advises creators to put keywords and hashtags in the caption, not the comments.
The search card in Meta's Transparency Center, updated June 23, 2026, lists what can appear in results: hashtags, places, reels, posts, profiles and audio. For keyword suggestions, the system compares the words in your search with the suggestion, counts exact matches and looks at how often people tap it. That leads to one rule: write words the way viewers type them.
Search words step by step
- Name the subject the way a buyer would: “cottage cheese pancakes”, not “a creamy breakfast treat”.
- Type that word into the search bar and write down the suggestions. They reflect what other people tap, so the wording is real.
- Put the main word in the first sentence and the details in the second: “high-protein”, “in a skillet”, “for kids”.
- For a local business, add the city or neighborhood: “coffee shop in Brooklyn”.
- Finish with hashtags. Since December 18, 2025, Instagram allows up to five hashtags in a reel or post.
Work the words into normal sentences. Nobody reads a comma-separated list to the end. Mosseri's search post also warns that accounts that post spam or break the guidelines may appear lower in results. Our piece on which hashtags to use covers how to pick them.
On-screen text: how many words and where to put them
An overlay stays short for two reasons: viewers need time to read it, and Instagram shows text-heavy videos less often. In his ranking explainer of May 31, 2023, Mosseri listed reels the system aims to make less visible. They include low-resolution or watermarked clips and clips that are majority text.
How many words
One overlay carries one thought. The test is quick: read it aloud twice while it is on screen. If you can't, cut words or keep the overlay up longer. The first overlay promises the result, the middle ones name the steps, and the last one shows what the first promised: a number or the finished result.
Where to place it
The handle, the start of the text and the audio name cover the bottom of a clip. A column of buttons runs down the right side: like, comment, share. Put the overlay in the upper half or the center of the frame and check it on a phone before posting.
Subtitles and overlays
Subtitles repeat speech word for word for people watching on mute. Keep the two at different heights: the overlay at the top, subtitles below the center but above the handle. Our guide to video format covers frame size, length and cover images.
A call to action without engagement bait: what the rules say
Asking for reactions just to get reach has a name: engagement bait. Instagram's creator FAQ lists content that is not recommended. The list includes clickbait, engagement bait and posts that promote a contest or giveaway. Clickbait means a teaser headline that promises more than the post delivers. Our article on getting recommended explains how recommendations work.
Facebook explained the term in December 2017, before the company became Meta. The example in the announcement asks people to like a post if they are an Aries. Facebook began demoting such posts in News Feed the week the announcement came out.
The same announcement named exceptions: posts asking for help, advice or recommendations. Its examples were a missing child report, a fundraiser for a cause and a request for travel tips. Facebook said such posts would not be demoted.
Bait versus a call to action
Bait asks for a reaction that has nothing to do with the video. A call to action follows from the value the viewer already got.
- Bait. “Like if you agree”, “Tag three friends”, “Comment yes so everyone sees this”.
- Saves. “Save this recipe for the weekend.”
- Comments. “Tell me which filling to make next.”
- Shares. “Send this to someone who eats breakfast on the run.”
Use one call to action, at the end of the text or as the last overlay. Don't leave comments unanswered. Instagram suggests liking or authentically replying to comments within the first 7 days.
Caption templates for three kinds of reels
The text follows one order in every template: first sentence, details with search words, a call to action and hashtags. Break the middle into short paragraphs, one thought each. The wording in the table is a sample, so swap in words from your niche.
| Video type | First sentence | Middle | Ending |
|---|---|---|---|
| Tip or how-to | “Three steps to cottage cheese pancakes that hold their shape” | One line per step, main words: cottage cheese pancake recipe | Ask for a save, then up to five hashtags |
| Product | “A backpack under the shower for 40 minutes: what's inside” | Material, volume, colors, city and delivery times | A color question for the comments and product hashtags |
| Personal story | “A year of waking up at 6: what happened to my sleep” | Time frame, a slip, the final number, what changed | Ask people to send it to a friend with the same habit |
What it looks like in full
Take the first row and build the full text. First sentence: “Three steps to cottage cheese pancakes that hold their shape”. The second sentence carries the search words: “High-protein cottage cheese pancake recipe”. Then three short paragraphs: “Step 1: drain the cottage cheese through cheesecloth”, “Step 2: add flour one spoon at a time”, “Step 3: fry under a lid”. Ending: “Save this recipe for the weekend” and three hashtags about pancakes and breakfast.
Which first lines work for accounts in your niche: what the report shows
The table above fits any niche, but every niche has its own words. The Reels Scripts and Hooks report collects the captions of reels that performed on your topic or hashtag. You borrow the structure of a strong first sentence and write your own. You don't need to log in.
- The first sentence of each text: what shows before “more”.
- Typical hook length and full text length.
- The share of texts that open with a question.
- The share of texts with a call to action.
- The words posts most often start with.
The report reads only the text below the video, not its first seconds or text overlays. It finds calls to action by a word list, so their share works as a guide rather than a precise measurement.
Name a topic or hashtag: we show the first sentences of text under videos that performed on it, their length and common words. No login needed.

How many hashtags should reel text have?
Up to five. Since December 18, 2025, Instagram allows no more than five hashtags in a reel or post. Mosseri's search post advises putting hashtags in the caption, not the comments. The end of the text is the easiest place for them.
Should the text overlay be repeated in the caption?
No. The overlay promises a result, and the text below adds details and search words. Repeating it wastes the visible part before “more”.
Can I ask for comments under a reel?
Yes, when the request follows from the video: pick a filling, ask for advice, share an experience. Asking for reactions just for reach counts as engagement bait, and Instagram does not recommend such content.
Where should on-screen text go?
In the upper half or the center of the frame. At the bottom, the handle, the start of the text and the audio name cover it, and buttons cover the right side.
