Hi @TomJr 
I have already looked into this method, and while it is possible to integrate an external blog into Sitely, I have concluded that it may cause SEO-related issues.
When a blog is embedded within a Sitely page that already has its own page title and meta description, search engines like Google may ignore the meta tags of the blog articles. They are likely to rely primarily on the metadata of the main page and generally do not take into account those inserted via an iframe or an external script.
As a result, blog articles may not be properly indexed, and their titles and descriptions may not be recognized correctly, which could reduce their visibility in search results.
If SEO is an important factor, it might be more effective to use a blogging system where each article has its own dedicated page with its own metadata. I have also mentioned some alternative solutions in this post:

Please note that I am speaking conditionally because I am not an expert on this topic, and I could be mistaken.
