Meta keywords are no longer used by Google or Bing to determine a site's ranking (relevance), so don't overthink meta keywords. Smaller search engines still might use them in their algorithm, so we recommend adding them anyway. They are invisible to site visitors both on your site on in the search engines.
How to create meta keywords
The meta keywords should follow these guidelines:
The meta keywords should be the same as the tags you're using in the article. The image below shows that I'm using the article's tags as its meta keywords.
Separate the keywords with commas.
Protip: While beneficial to add to your website pages and blog posts, meta keywords don't hold as much weight as they once did for on-page SEO.
What is a tag?
Tags are often called "categories" on other blog tools like Wordpress. They're used to make it very easy for your readers to find a topic they're interested in on your blog. All the tags that you use in each of your blog post will be listed on your blog sidebar if you have the tag module installed.
How to create blog tags
The tags on each blog post should follow these guidelines:
Add no more than three tags to each blog post.
The tags you choose should be a little broader than long-tail keywords, as you are summarizing the topic of the blog post.
The tags should be used in the blog article's meta keywords.
In HubSpot, we call them topics. You can edit them by heading to the "Options" tab of your blog editor.
