Go to Blog Settings
Click on the Blog link in the Content Optimization System Options side menu.
Choose the blog for which you want to update settings
Choose the blog that you'd like to modify. If you only have one blog, you'll only see one option in the drop-down menu.
Modify your blog comments settings
Scroll down to the Comments section to modify your blog comments settings. You can choose to allow new commentaters to become contacts in your account, notify members of your team when a comment is posted, close comments on a post after a set number of days, require commenters to prove that they're human before they can post, and choose how many comment threads you want to allow.
Allow comments on your blog
You can choose to allow or not allow comments on your blog. The box is checked and comments are allowed by default because outside of social media comments are one of the best ways to publicly engage your audience in discussions about your content and business.
Allow comments to create contactsYou can choose to allow HubSpot to create new contacts when a visitor comments on your blog. With this setting enabled, new commentators will be added to your contacts database within HubSpot. Please note that comments made by existing contacts will always be attributed to those contacts even if this setting is disabled.
You have the option to moderate comments on your blog posts so that comments can't be automatically posted to your posts before someone on your team approves them. HubSpot automatically filters for spam comments and will hide them from your posts, but you can use this option to not allow any comments whatsoever without prior approval.
To moderate your comments go to Content > Blog > Comments. When a new comment is posted you will find it under Pending comments. Check the box next to a comment and click the plus icon button to approve it. You'll also have the option to Reject, Mark as Spam, or Delete the comment.
Close comments after this number of days
You have the option to automatically turn off the ability to leave new comments on posts that are older than a specific number of days. This is useful if you have a blog that tends to have more time-sensitive posts or if you want to limit commenting for some other reason.
Always require commenters to fill out a CAPTCHA when commenting
You have the option to require that commenters fill out a CAPTCHA when they are commenting on your post. This will make it harder for spammers to leave comments on your blog, but keep in mind that this might also dissuade people from going through the extra effort to comment.
Require CAPTCHA after this number of days
You have the option to enable a CAPTCHA after the post has been published for a certain number of days. This is really useful if you want to encourage a discussion early in the post's lifespan and want to ensure that any comments after a certain time period are still relevant and aren't spam.
Who should receive notifications of new comments on this blog?
You can select the users on your HubSpot account that you want notified via email when a new comment is posted on your blog.
How many levels of comments do you want to allow?
Choose how many layers of comments you want to allow on your blog posts. You can have up to 10 levels of comments. In order to enable threaded comments, you must select a number greater than 1.
Comment Verification Text
You can customize your thank you text to display when a commenter posts a comment successfully.
