The guide
What the x keyword research tool does, how to use it, and what to do with the result.
An X keyword research tool shows you the phrases people type into X search, formerly Twitter, and how often they search them. Enter one seed keyword, such as ai agents, and choose a country from 47 markets. You get a list of real X search suggestions built around your seed, each with an estimated monthly search volume, a 12-month trend line, a trend percentage, and CPC and competition where data exists. Sort by any column, narrow the list with include and exclude words, and export it as a CSV to plan posts, threads and hashtags.
How to Use the X Keyword Research Tool
Start with the topic you want to post about, written the way someone would type it into the X search bar, such as ai agents, remote jobs or home espresso. Enter it as your seed keyword, choose the country your audience is in, and run the search. The tool returns the phrases X suggests around that seed, sorted by estimated search volume. Read the list and mark the phrases you can say something useful about, then sort by trend to see which ones are gaining interest. Type a word into the include box to keep only phrases that contain it, like tools or jobs, and use the exclude box to drop anything off topic. Export your shortlist as a CSV and turn each phrase into a post or thread.
What the X Keyword Search Results Show
Each row is one phrase from X search. Volume is an estimate of monthly searches for that phrase on X, averaged over the last 12 months, and the small line chart beside it shows how those months moved. Trend is the percentage change across that period, so a green number means interest is rising and a red one means it is fading. CPC and competition appear where data exists and hint at how commercial a phrase is. Above the table you see the number of keywords found, their total volume and the average CPC. X does not publish search numbers, so the volumes are estimates. Use them to compare phrases with each other, such as ai agents explained against ai agents news.
How to Use X Keywords in Posts, Threads and Your Profile
Put your main phrase in the first line of a post, because that is what shows in search results and previews. Standard accounts get 280 characters per post, so write the keyword plainly and spend the rest on a clear point or question. For longer topics, start a thread with the keyword in the opening post, then use related phrases from your list in the posts that follow. Add your core topic words to your bio and display name so your profile appears when people search them. Hashtags work best in small numbers on X: one or two specific tags built from your keyword phrases are easier to read than a long string of popular ones.
X Keyword Search vs Scanning X for Mentions
People who search to scan Twitter for keywords usually want to find live posts that mention a word, such as their brand name. This tool does something different: it shows which phrases people search for and how often, so you can write posts that match. To find existing posts, use X's own search with advanced operators. Put a phrase in quotes to match it exactly, add from:username to see one account's posts, use a minus sign before a word to exclude it, and add lang:en to limit the language. Use the two together: keyword research tells you what to post about, and X search shows who is already talking about it and what they say.
Twitter Keyword Research for Brands, Founders and Creators
Brands use X keyword research to find the questions customers ask about their category, then answer them in posts and replies with the same wording. Founders building in public use it to see how people describe the problem their product solves, and which of those phrases have the most searches, before writing launch posts. Creators and newsletter writers use the trend column to spot angles that are gaining interest and plan a series around them. Community managers turn high-volume phrases into hashtag ideas for events and chats. In every case, one seed per topic is enough to start, and repeating the same keyword and country within 30 days returns the saved result at no extra charge.
Common Mistakes With X Keywords
The most common mistake is stacking hashtags and keywords until a post reads like a list. On X, posts are short and people scroll fast, so one clear phrase beats five crammed ones. Another mistake is posting only on the biggest terms, such as ai or marketing, where your post competes with millions of others. A longer phrase with lower volume and a rising trend, like ai agents for small business, reaches people with a specific interest. A third mistake is treating keyword research as a one-off: conversation on X moves quickly, so run your main seeds again when news breaks in your field. Finally, keywords cannot rescue a post with nothing to say.

What are the best keywords to use on X?
The best keywords are specific phrases your audience already searches, ideally with steady volume and a rising trend, such as ai agents for small business rather than ai. Pick one per post, put it in the first line, and use one or two hashtags at most.
Can I research X keywords for a specific country?
Yes. Choose from 47 countries before you search, including the United States, United Kingdom, India, Canada and Australia. Suggestions and volumes reflect that market, so run a separate search for each country your audience is in.
