X Hashtags and Trending Topics

Lisa Kalner Williams

Keyword Tool Pro is my first stop when investigating and vetting ideas for our blog posts. It's incredibly easy to use and understand which saves me tons of time in content development!

Lisa Kalner Williams, Content Marketing Director, Agorapulse

The hashtag is now a core feature for large social media platforms like Facebook, Instagram, and YouTube. But it was first made popular by X in 2007.

Hashtags are a useful way for X users to join in related conversations among users locally or globally or keep updated to the latest hot news. It can also be used to reach out to more users and gain more X followers. Many X hashtags went viral globally, such as #Bahrain, #ThankYouSirAlex, #Adele, #Skyfall, #ThankYouLeeChongWei, and #Tigerblood.

Businesses often use hashtags to gain more visibility by using branded hashtags for special campaigns. Some brands use guerilla marketing methods to make a hashtag go viral organically, while others use X Ads and promoted trends.

Note: Tweets or hashtags that are trending on X are be based on a user's location.

X, a One-of-a-Kind Social Media Network

X is a popular social media network and microblogging platform with hundreds of millions of active users worldwide. Founded by Jack Dorsey, Noah Glass, Biz Stone, and Evan Williams in 2006, the platform has grown into one of the most influential social networks on the web.

Many big brands and famous celebrities are active on the platform, and X Ads enable paid posts to be promoted to a wider audience.

X made the use of hashtags and trending topics mainstream. Users can follow or join in conversations of trending hashtags either locally or globally by clicking on X hashtags or appending a trending hashtag to their post. You can also find hashtags through the X search function.

How X Works

Peder Alstermark

I need a tool which gives me the relevant keyword variations with search volume, and lets me easily copy these over to spreadsheets. Keyword Tool makes this easier than any other tool I've tested.

Peder Alstermark, SEO Consultant, We & Partners

It was first created as an SMS-like broadcast service for sending short messages to a group of people. Posts on the platform - historically called tweets - are built around short, skimmable writing, though paid subscribers can post considerably longer content. Brevity is still the platform's DNA, which is why hashtags and keywords matter so much on X.

Anyone can register on X for free for personal use to connect with friends or others all around the world or you can use X for business. Brands and companies often use branded hashtags and include X Ads into their digital marketing campaigns.

X also has a search function that allows users to enter certain keywords to search on X. The result will show tweets and users that are related to the user's search term. There is also a powerful X advanced search feature. It enables users to find exact keywords, hashtags, users, and locations based on specific dates.

X Advanced Search or Keyword Tool for X?

The X advanced search features have come a long way. What used to be a simple and straightforward search function has now become incredibly powerful, with the ability to narrow down searches to exact match keywords, profiles, languages, and time.

When you go to the X advanced search page, you will find many input boxes with a variety of search variables. It may look simple but is actually far from user-friendly. You will also notice a "These hashtags" box where you can input a hashtag and it will show you a result of accounts and tweets that carry that hashtag.

As you can see, the X advanced search is useful mostly for the end user and not the content creator or poster. You can search for keywords or hashtags but it will not give you ideas for other related keywords and hashtags.

On the other hand, Keyword Tool for X is perfect for content creators and marketers looking to amplify their reach on X by using high-volume keywords and hashtags. When you enter a keyword, topic, or hashtag in Keyword Tool, it will automatically generate thousands of relevant keywords and hashtags that you can use.

X is similar to other major social media platforms but also functions differently. It is used by most people as a platform to connect with people through quick, short messages, a microblogging platform, and a place to share snippets of information and news.

Users can post tweets on their X timeline, retweet posts by others, reply to other tweets, or favorite selected tweets. Other than publicly tweeting, users on X can also send direct messages to each other (a feature that can be disabled to prevent non-followers from direct messaging you).

Usage of X spikes around major world events - elections, sporting finals, natural disasters, product launches, cultural moments. When thousands of users post about the same topic or share the same hashtags, it often surfaces as a trending topic in X's Trending section.

X remains one of the fastest real-time sources of breaking news on the internet, frequently surfacing stories, eyewitness accounts, and first-hand reactions before traditional media publishes them.

Over the years, X has put in place many measures to prevent the spread of hate speech, harassment, and cyberbullying on the platform. It is important for both users and businesses alike to keep updated with X's latest terms and conditions and its rules and policies.

Aside from personal use, X has also grown in popularity for its X Ads for brands and businesses.

How X Ads Work

X for Business is an incredibly useful feature to gain better visibility and reach a large audience. Although X is not as widely used for paid social campaigns as Facebook, Instagram or YouTube, X Ads are well-known for its unique ad targeting features and cost-effectiveness.

The types of X Ads can be summarized to Promoted Tweets, Promoted Accounts, and Promoted Trends. The targeting features for X Ads are unlike other social media platforms.

For a X business account, you will be able to promote your tweet to a specific audience, your own trending topic, and account to a wider audience. Businesses are able to use X Ads to amplify their brand, raise more awareness, and even gain more X followers.

X business accounts are also able to leverage X Ads to gain awareness, tweet engagements, get website clicks, and attract app installs.

X Ads is also a great choice for businesses with a smaller marketing budget. The cost of X Ads is not known to be as high as other large social media platforms (except for paying for Promoted Trends, a targeting feature that is native to X). There is no minimum budget needed and you only need to pay for results that you specify.

Search X for Keywords and Hashtags for X Ads

Altan Çolak

Keyword Tool helps us not just in keyword research, but also in pitching potential customers. We clearly show them what keywords they are missing out in their PPC and SEO.

Altan Çolak, Founder & CEO, Sempeak

X Ads are targeted mainly through keywords, hashtags, and user accounts. For example, if you are a business that sells sports shoes, you may want to reach a relevant audience that might be more inclined to buy your product. To promote your brand and product effectively through X Ads, you will need to know relevant, high-volume keywords.

One way is to use the X search function to find user accounts that have a lot of X followers and hashtags related to your industry. It can be done but it will be a tedious and time-consuming task, even if you use the X advanced search feature.

Instead, you can use Keyword Tool for X. Just enter your desired topic, niche, or keyword into the search box and press enter. From the results, you will see a long list of related hashtags and keywords that you can use for your X Ads.
