Don't use periods in titles

It's a well established copywriting principal to never use periods, also known as "full stops," in titles or headlines. For example, look at any newspaper.

. . . the reason goes beyond how it looks and is more about the signal that it sends to your reader. Full stops, like their name suggests, are something that halts the eye of your reader.

This isn’t something you want at this point in your post. Titles are all about leading your reader into your post and so anyway that you can help this flow is a bonus.
