Why am I seeing SEO errors for my HubSpot-hosted content?
External SEO tools will often return errors when crawling HubSpot-hosted content. For example, you may see 401 errors or warnings for your blog listing page, or the blog RSS feeds. Both of these links change when a new post is published, and as a result these links are set to expire.

While these resources may be blocked or flagged, they do not mean that your page itself has not been crawled. This error might look like the following:
