This plugin hasn’t been tested with the latest 3 major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.

Smart Hashtags [#hashtagger]


The Smart Hashtags Plugin allows you to use #hashtags, @usernames and $cashtags in your posts

This plugin uses the WordPress Tag system to automatically convert a #hashtag into a Post Tag. Each #hashtag is added as a “normal” tag (without leading hash) to the post, so it is fully compatible with existing tags!

Retired Plugin

Development, maintenance and support of this plugin has been retired in october 2023. You can use this plugin as long as is works for you.

There will be no more updates and I won’t answer any support questions. Thanks for your understanding.

Feel free to fork this plugin.


Just type anywhere in a post

This adds “hashtag” as tag to the current post and on links to tag archive page for “hashtag” when showing the post.

Use +#hashtag to only link to a tag archive page without adding “hashtag” as tag to the post. When showing the post the link is showed as “#hashtag” (without “+”). If the tag does not exist the text remains unchanged and no link is created.

Use duplicate ##hashes to tell the plugin that this word should not be converted into a tag. Duplicate hashes are replaced by a single hash when showing the post.

This creates a link either to the Profile Page or the Website of User “username”. The usage of @usernames can be activated optionally. If the username does not exist the text remains unchanged and no link is created. It is highly recommended to use @nicknames instead of @usernames to enhance security.

Use @@username to avoid link creation. When showing the post this is displayed as “@username” without link (@username feature has to be activated).

This creates a link to the concerning stock symbol at MarketWatch, Google Finance, Yahoo Finance or StockTwits. The usage of $cashtags can be activated optionally. $cashtags link to the concerning stock symbol at MarketWatch, Google Finance or Yahoo Finance. Notice: stock symbols can not be validated, using a invalid stock symbol will cause an not found error on the target site.

Use $$cashtag to avoid link creation. When showing the post this is displayed as “$cashtag” without link ($cashtag feature has to be activated).

WordPress Security

If you activate the @username feature it is highly recommended to use @nickname instead of @username!

Post Types and Section Types

It is possible to use #hashtags, @usernames and $cashtags on Posts, on Pages and on Custom Post Types within Content, Title and Excerpt. Activate only the Post Types and Section Types you want to be processed to avoid unnecessary processing for best performance.

Formatting links

Additional CSS Class(es) to add to the #hashtag and @username links can be configured on the plugins setting page.

Display of links in front end

Optionally all symbols (#, @, $) can be removed from the links generated in front end.

Display of Tags in front end

There’s an option to automatically add a hash symbol in front of tags (e.g. when using the Tag Cloud Widget).

This is a plugin that I’ve used before and am using now as well. It works out of the box very well. However, this time, when I installed it, the nag screens asking to follow the creator on twitter turned up everywhere on the admin screen even before I had a chance to use the plugin. If the creator were to change the plugin so that the nag is less intrusive, I’ll consider changing my review as well as increasing the rating to 5 stars

Needs to keep up with PHP/Wordpress changes, and might be some other functionality with other things like the @ symbol, maybe to factor in some semantics (e.g. when a hashtag is a location, or an emotion, etc.), maybe colourings but really, there’s not anything I can think of to complain about. Just so much potential and in itself, great as it is 🙂 Brilliant piece of work!

This plugin functions perfectly as described, with a lot of intuitive settings and options (with clear descriptions). This only tags single words, no spaces, similar to how social hashtags work. I give it five stars.
