How to use hashtags on social media in 2026: A guide for Canadian small businesses 

TL:DR

Hashtags now play a supporting role in social media marketing. They help label a post, connect it with a topic and make it easier to find through platform search.

They do not guarantee reach.

For better results:

Your content should make sense without its hashtags. The tags should add useful context.

Social discovery starts with clear content

A potential customer wants to find a bakery for a birthday cake, a contractor for a basement renovation or a local shop selling Canadian-made gifts.

Where do they look? A growing number of searches now happen inside social platforms. People enter a question, product, service or location into a search bar. They also find businesses through recommended posts related to their interests.

This shift changes the purpose of a hashtag. Adding #SmallBusiness or #SupportLocal to every post does little to explain what you sell, where you operate or why someone should choose you. A clear description such as “custom birthday cakes in Mississauga” gives people and the platform more useful information.

Hashtags still support this description. They are one part of a larger discoverability strategy built around relevance.

What role do hashtags play in social media search?

A hashtag turns a word or phrase into a searchable topic label.

For example, TorontoFlorist identifies an industry and location. #WeddingBouquetIdeas identifies a specific customer interest. #CanadianMade identifies a broader buying preference.

These labels serve several practical purposes:

Their value depends on context. A relevant tag reinforces your message. An unrelated tag adds noise.

Search systems also read more than hashtags. LinkedIn lets users search posts with keywords or natural, conversational language. Users can still enter hashtags in the search bar, even though the suggested search feature does not recommend them. 

TikTok has also built search products around keywords and search terms. Its business guidance stresses the importance of relevance between the words people search, the selected keywords and the content itself. 

The practical lesson for an SMB is simple. Describe the post clearly first. Select hashtags after the main message is in place.

Build each post around a search need

Before choosing a hashtag, identify what your ideal customer wants to know.

For example: a café might address:

Choose one main topic for each post. Use the central phrase in the caption, on-screen text or video narration. Add hashtags closely tied to the same topic.

This creates a consistent set of signals.

Example:

Weak caption: New treats are here! #Food #Yum #Trending #Explore #Viral

Stronger caption: Looking for fresh croissants in downtown Ottawa? This weekend’s pastry menu includes butter croissants, almond croissants and pain au chocolat.

Supporting hashtags: #OttawaBakery #OttawaEats #FreshCroissants

The stronger caption tells a customer what is available and where to find it. The hashtags reinforce those details.

How many hashtags should your business use?

There is no single number suited to every platform, industry or post.

A better starting point is to use the fewest tags needed to describe the content accurately.

For most posts, select tags from three groups:

Add a branded or event hashtag when it has a defined function. This approach helps you avoid a long block of repetitive tags. It also forces each hashtag to earn its place.

Do not treat any recommended number as a fixed rule. Test different quantities against your own results. A neighbourhood restaurant, online consultant and national retailer will see different audience behaviour.

Which types of hashtags support discoverability?

Local hashtags: Local hashtags help connect a post with a city, province, neighbourhood or regional community.

Examples: #MississaugaEats, #MadeInManitoba, #HalifaxSmallBusiness, #ShopLocalCalgary

Use a local tag when people must visit, book or buy within a defined area. A location tag provides less value for a post aimed at customers across Canada.

Before using one, search it on the platform. Review whether the results match your audience and business category. A popular city hashtag might feature many unrelated posts. A more precise city-and-industry tag might attract fewer views but stronger interest.

Industry hashtags: Industry hashtags state the field or category connected with your post.

Examples: #CanadianRetail, #RestaurantMarketing, #SmallBusinessAccounting 

Broad tags often contain a high volume of content. Pair them with a more specific tag to clarify your subject.

Niche hashtags: A niche hashtag reflects a focused need, product or community.

Examples: #GlutenFreeOttawa, #FirstTimeHomebuyerTips, #RestaurantHiringCanada, #SustainableGiftIdeas

These tags help narrow the topic. They also tend to describe stronger intent than a general label such as #Business or #Shopping.

Branded hashtags: A branded hashtag belongs to your business, campaign or recurring content series.

It works well for:

A branded hashtag does not create an audience by itself. Your business needs to explain why people should use it.

Keep the tag short, easy to spell and distinct enough to find. Search it before launch to see whether another organization or community already uses it.

How should hashtags change by platform?

Instagram

Use hashtags to classify the post and reinforce its topic. Put the main searchable phrase in the caption rather than depending on tags alone.

For a local service, combine the service with the location: #TorontoDogGroomer, #EdmontonLandscaping, #MontrealWeddingPhotographer

Avoid filling the caption with broad tags such as #Love, #Happy or #InstaGood. They reveal little about the business or post.

TikTok

Treat hashtags as part of the video’s search context.

TikTok’s Search Ads guidance states that content relevance depends on the relationship between search queries, keywords and the creative. Its recommendations for search ad titles include matching user intent, using targeted words in titles and descriptions and aligning the creative with selected keywords. 

For organic content, apply the same communications principle as an SMB best practice:

A generic tag such as #FYP does not describe your offer, location or audience. A phrase such as #OttawaBrunch provides clearer context.

LinkedIn

Keywords deserve priority on LinkedIn.

The platform supports searches for posts using keywords and offers filters for content type, author, company, industry and date posted. 

Write a clear post about one professional topic. Then add a small set of relevant hashtags if they help label the subject.

For example: #CanadianRetail, #SmallBusinessFinance, #CustomerExperience

Place them at the end rather than inserting one into every sentence. Readability matters more than hashtag volume.

Facebook

Use hashtags selectively on Facebook.

They are most useful for an event, campaign, community topic or recurring series. Clear copy, accurate Page information and direct engagement with customers deserve more attention.

A local business posting about a community market might use the official event hashtag and one location tag. A routine business update might need none.

YouTube

Focus on a descriptive title, clear video subject and useful description. Add hashtags only when they help identify a series, topic or campaign.

Resist the urge to overload your description with hashtags. YouTube's Help Centre states that if a video or playlist contains more than 60 hashtags, YouTube ignores all of them. It also notes that adding too many hashtags can make them less relevant to viewers searching for content.

Instead, use a small number of highly relevant hashtags that support your video's topic. Your title, opening seconds and description should do most of the work when it comes to helping viewers understand the value of your content. Up to three hashtags from the description may appear above the video title, giving you another reason to choose them carefully.

How do you research hashtags without paid tools?

Start inside the platform where you plan to publish.

Step 1: Search the customer’s phrase

Enter a product, service, question or location. Note the language used in relevant results.

Step 2: Review suggested searches

Suggested phrases reveal related topics. LinkedIn supports keyword and conversational searches, while TikTok distinguishes between the terms selected by advertisers and the terms entered by users. 

Step 3: Open the hashtag results

Look at the content attached to a prospective tag.

Ask:

Step 4: Review local accounts

Look at businesses, creators, associations and event organizers serving the same region. Pay attention to the terminology they use, without copying their full hashtag sets.

Step 5: Build a small reference list

Organize possible tags by:

Use this list as a starting point. Select tags based on each post instead of pasting the same group every time.

Which hashtag mistakes reduce clarity?

Using broad tags with no clear purpose

Tags such as #Business, #Success or #Viral apply to too many posts. They give little information about your offer or audience.

Copying the same list onto every post

A post about a new product should not use the same tags as a hiring announcement or educational video. Match the tags to the individual topic.

Following trends unrelated to your business

A trending tag might expose your post to more people, but those viewers might have no interest in your offer. Unrelated tags also weaken the connection between your caption, creative and topic.

Repeating every caption word as a hashtag

A caption already provides context. Choose tags that add a useful classification, rather than turning each word into a label.

Using tags without checking their meaning

A phrase might already belong to a campaign, community or cultural conversation. Search a tag before your business adopts it.

Ignoring accessibility

Long strings of hashtags are difficult to scan. When a hashtag contains several words, capitalize the first letter of each word.

Example: #SupportLocalBusiness is clearer than #supportlocalbusiness

Relying on hashtags to fix unclear content

A post still needs a useful idea, direct wording and a reason to engage. Hashtags do not replace a strong opening, helpful information or a clear next step.

How do you measure hashtag performance?

Do not judge a hashtag strategy by reach alone.

Review whether each post produced meaningful actions, including:

LinkedIn’s post analytics include impressions, members reached, profile viewers, followers gained, reactions, comments, reposts, saves and sends. The platform notes that some figures are estimates. 

Run a simple test over several posts. Keep the content format and topic reasonably consistent. Change one part of the hashtag approach at a time. For example, compare a local tag with a national tag or three focused tags with a longer list.

Record the results in a spreadsheet or content tracker. Look for patterns across several posts rather than using one high-performing post as proof.

A 10-minute hashtag workflow for small businesses

Before publishing, follow this process:

This process keeps hashtags in their proper place. They support the content rather than direct it.

Make your business easier to find

Your customers do not search for a collection of popular tags. They search for answers, products, services and nearby businesses.

Meet that need with specific language.

Explain what you offer. Name the problem you solve. Include your location when it matters. Answer one useful question at a time. Then add hashtags that strengthen those signals.

A focused hashtag will not turn an unclear post into a strong one. Paired with useful and searchable content, it gives your post one more path into a relevant conversation.
