Do hashtags work on Pinterest?

You can use them, but Pinterest does not say they add reach. Its advice is keywords in the title and description, and only 19% of the most viral Pins in Tailwind's study used hashtags.

How many hashtags can you use on Pinterest?

Pinterest publishes no limit. Hashtags are part of the description, which holds 800 characters.

Where do hashtags go on Pinterest?

In the Pin description. Pinterest's Help Center says to write a description, where "you can also include hashtags".

How many hashtags should I use on Pinterest?

Pinterest gives no number. Tailwind advises 2 to 8, but most of the viral Pins in its own study used none, so a few specific tags or none at all both work.

What are tagged topics on Pinterest?

Topics you pick when you create a Pin in the app, up to 10. Pinterest says they help "people searching for similar ideas find your Pin".

Should I use hashtags or keywords on Pinterest?

Keywords. Pinterest's July 2025 guide says to use "relevant keywords" in the title and description, and it does not mention hashtags.

Do hashtags count toward the Pinterest character limit?

Yes. They are part of the description text, so they count toward its 800 characters.

Can a scheduler add hashtags and topics to a Pin?

Hashtags, yes, as text in the description. Tagged topics, no: Pinterest's API has no field for them, so they are added in the Pinterest app.

Is there a penalty for using hashtags on Pinterest?

Pinterest has not said so. Tailwind's study found "there likely is not any penalty", with some viral Pins carrying up to 30 hashtags.

Can OmniSocials save hashtag sets?

Yes. Save sets in the composer and add one to a Pin in a click, or let your AI agent apply one through the MCP server.

Pinterest publishes no hashtag limit. Hashtags count toward the 800-character description.

The short answer

No published limit. Hashtags are optional; keywords do the work.

Pinterest's Help Center says you can write a description and "also include hashtags", but it names no limit. Its old hashtag help article now sends you to the Help Center home page. In the app you can also tag up to 10 related topics, which Pinterest says help "people searching for similar ideas find your Pin".

Pinterest's own advice is about keywords: "Always include a Pin title and description, using relevant keywords" (July 2025). In Tailwind's study of about 1.2 million Pins, 19% of the most viral Pins used hashtags, and Tailwind found "there likely is not any penalty" for using them.

Tips

Let keywords lead. Hashtags are optional.

Put keywords in the title first
Pinterest's advice is a title and description "using relevant keywords". It says the first 40 title characters are the most likely to show.
Write the description for search
Pinterest says descriptions "are used by our algorithm to determine relevance for delivery". Describe the Pin in plain words people search for.
Add a few specific hashtags, or none
81% of the most viral Pins in Tailwind's data used no hashtags at all. If you add some, keep them specific to the Pin.
Tag topics in the app
Up to 10 related topics help people searching for similar ideas find your Pin. The API has no field for them.
Keep it readable
Most descriptions in Tailwind's study used five or fewer keywords. A clear sentence beats a block of tags.
Save your best sets
Keep a short set of hashtags for each main topic, so every Pin on that topic gets the same tags without retyping.

How we built this guide. Checked on October 17, 2026.

The rules come from Pinterest's Help Center, its business blog and its API reference, read on October 17, 2026. Pinterest publishes no hashtag limit, and its old hashtag help page now redirects to the Help Center home, so the page says "None published" instead of repeating the figures other guides quote. The usage numbers are Tailwind's vendor data.
