The active users of TikTok must be aware that some comments below videos appear in blue rather than the usual black color. The "blue comments on TikTok" have become popular among the creators and the marketers. Some people wonder what they mean. What's so special about them? How can they get the blue color in replies?
This brief guide is all about the full rundown on Blue colored words in comments, and you will get all the answers to your questions, like what they are, how they all work, why it's so valuable for growth and engagement, and how you can (ethically) try to get more blue comments. We will also elaborate on keyword integration in replies. So let's start!
Blue comments (or sometimes referred to as "blue search comments" or "clickable comment keywords") refer to sentences in which some of the text is displayed in blue color. The blue text serves as a functional, navigational role in the app's search system.
In other words, those blue words are clickable keywords or search terms. When you tap a blue word in a comment, TikTok will run a search for that term. TikTok’s algorithm finds certain words (or word combinations) within comments and “upgrades” them into search links.
The TikTok algorithm automatically highlights certain keywords in comments when finding them relevant, popular, or useful as search triggers. No user can manually set any word or comment blue in this app.
For example, if any user enters "chocolate cake recipe," and the algorithm identifies "chocolate cake recipe" as something searchable, then it will show in blue text to all viewers. Clicking on it will take users to search results. We can say that they are reference links or hashtags.
Have you ever left a comment below any video and noticed that certain words suddenly turned blue? This is the app's new discovery feature. These “blue words” are searchable, relevant, or trending. Let’s break down exactly how and why this happens.
Keyword Relevance & Popularity: Whenever any word is being highly searched in TikTok or trending in the app, the algorithm may choose to highlight it in comments.
Contextual Match: TikTok wants its search engine to be smarter, interactive, and relevant. That's why it links blue words to search results. Through this feature, content creators and viewers get connected easily.
Time and Algorithmic Testing: Sometimes the app experiments with new highlights, so what looks blue this afternoon may not tomorrow. The platform’s algorithm keeps looking for search volume of the word, regional trends, and TikTok engagement levels.
These blue comments can also earn you real rewards, and here's why it's significant:
Greater Visibility & Discoverability: Blue comments function like a mini search widget, directing users to the relevant page and enhancing the searchability and reach of specific topics.
Authority & Social Proof: The blue colour differentiates clickable comments from ordinary comments, making them look more authentic and credible.
Greater Opportunity for Interaction: Humans tend to click or engage with blue text more than regular text. The additional "interactivity" can generate more likes, comments, and even increase TikTok followers.
Signals for the Algorithm: Blue comments can also serve as an indication to the TikTok algorithm regarding related terms and a specific niche. It is easy for TikTok to categorize video content and promote it to related communities.
It's the platform's algorithm to highlight any text in blue; no creator can do it, but by applying the right strategies, you can enhance its chances. Below are some actionable tips from our side.
While leaving comments, look at TikTok for trending niche-specific keywords or terms. Using strong keywords can also boost engagement on TikTok.
Put in phrases naturally, don't stuff in random buzzwords. For example: Rather than "nice video," if "plant care tips" is trending in your niche today, type, "Great video! Would love to see plant care tips for indoor succulents.
Long comments with lots of words reduce the chances of selection by the smart engine. The algorithm prefers short comments with an obvious word below the TikTok video.
Be on time when the video gets posted. The algorithm crawls comments shortly after the upload time, so comments left soon may be better selected. In addition, keep the content of your comment similar to the theme of the video (don't hijack it)
When you add a valuable comment on trending videos, you've got better chances
Always check the type of phrases (e.g., two-word phrases, noun phrases), observe common patterns, and adjust accordingly.
Avoid spamming comments with repeated phrases in multiple videos. That looks less authentic and reduces the chances of getting a blue mark.
Blue comments are part of the engagement ecosystem and play a vital role in account growth. Let's see how:
When you reply to TikTok comments (particularly where the content is strong), you establish rapport, generate more conversation, and increase the video's comments count—a key engagement metric. A creative response hooks other viewers and compels them to share their opinions or search for specific terminology.
As one Reddit user narrated it this way: I answer all the comments that I receive because I want every single one of them to know that I do see them. The viewers are more likely to come back when they get a warm response. So, comment + respond = stronger engagement loops.
Adding a question and a call-to-action like ("What do you think?", "Tag someone who..." ) and pining interesting/attention-grabbing comments sparks discussions. This type of feeding can overall enhance the organic reach of content and accounts.
Here's how the flow is:
Upload a video.
One leaves (or you leave) a comment, and TikTok turns it blue.
Someone sees that comment, clicks on the blue sentence, and follows that route
They view your video (and potentially your profile)
They like/comment/share, and maybe even follow you
Through integrating the comments and replies in intelligent ways, you can convert passive visitors into fans.
Creators can also target keywords in comments for SEO goals. To get specific keywords, try TikTok Creative Centre, or use the search bar to see the auto-suggestions. Choose words with good search volumes.
Experiment with the combination of niche-specific keywords: e.g., "how to give easy plant care tips," "summer outfit ideas 2025," etc. Adjust these words in the middle or at the back of the sentence. Do not use filler sentences; be precise. Instead of "this is amazing, I love cooking hacks," you may try "amazing video! Cooking hacks for beginners?
Keyword stuffing can be penalized or ignored. Add keywords naturally that look authentic, and the algorithm prioritizes them.
Here we would like to share a few misconceptions that TikTokers have in their mind.
The algorithm has too many internal filters, and there is no guarantee that your expected text will be turned blue.
Some think that “Blue comments always boost a video’s reach dramatically.” That's not true.
They do count, but it's no magic wand the other metrics (video quality, view time, engagement) count more.
A few smart users believe that they can pay or hack the system in order to get blue comments.
It is not impossible to buy legit buy blue comments, but you can buy simple comments on TikTok to boost engagement from a trusted source like LikesForYou.
The blue highlight might change over time as TikTok updates its algorithms or re-indexes comments. So one should not think that once I receive a blue note, it lasts forever.
These are some comment templates for user brainstorming. Have a look! Add your creativity in it according to your niche and post them with confidence.

A creator should know how to incorporate the trending keywords in a sentence. After publishing a video during the peak hours, immediately post short and engaging comment. Respond to comments because the first hour after publishing a video is crucial. It sends a signal to the algorithm about engagement.
Over the next few hours (or days), check the comment section for blue highlights. If one of your comment’s keyword phrases is highlighted, you succeeded. If not, you learn from that result and redefine your strategy. Focus on analytics and monitor which keywords turned blue, which didn’t. In case you are not getting blue comments, adjust style, keyword selection, timing, etc.
Blue comments are clickable search terms by the algorithm. These blue-highlighted keywords boost engagement and visibility. TikTok creators have no control over them, but they can increase the chances of getting blue keyword-based comments by focusing on timings.
These comments should be part of the holistic growth strategy of every creator. Here we must mention that it is one metric, interactive content, views, likes, and shares are also important. We hope this guide will help you achieve the blue comments on your posts in the future.
