Ditto what Sergey said, ggt—000G is correct for the reasons she stated.

The title of any newspaper article or blog post is usually a link to the permanent URL for the article. If you’ve ever seen the term “permalink” on a blog, it refers to that permanent URL, which is always longer than just the domain name.

The easiest way to avoid the problem is to always click on the title of the article or blog post, then go ahead and create your Page from the resulting URL.
