In HTML, if a full sentence is used for a link, should its terminal punctuation (i.e., period) be included in the linked text?

Consider these two examples:

<a href="about:blank">Watch the video on YouTube</a>. <a href="about:blank">Watch the video on YouTube.</a>

Is this just a matter of personal preference, or is one of these more readable than the other?

Edit:

It seems that there's some confusion - and certainly a valid related discussion - about including an actual URL (in part or whole) within the link text.

Consider the following:

<a href="...">Watch the video here.</a> <a href="...">Watch the video on YouTube.</a> <a href="...">Watch the video on youtube.com.</a>

I think most would agree that including the period in the third example is bad practice; it creates multi-period confusion with respect to the ".com" in the link text.

For purposes of this question, I'm specifically wondering about the former two examples that do not include ".com" in the link text. (Although one might make a convincing argument that using "YouTube" without the ".com" is still problematic by proxy. If so, let's assume I'm asking about only the first example: "Watch the video here.")
