Hey Anthony,

The Headers tags are a usability feature.They're used to guide users on your site. Regardless of the name, a big part of SEO is user experience. Try to think of your headers from a users perspective.

1. While styling your headers is recommended, I suggest a larger font size for your headers than for your paragraph fonts.
2. Use the version that flows better and the keyword with more exact match search volume.
3. For most sites, I use H1 for site title, H2 for page/post titles, and H3s as document headers (I.E. Intro, Instructions, Conclusion, etc)
4. In your example you didn't use exact matches of your 2 keywords. So actually your keywords become "driving school in London" instead of your proposed "driving schools London" and "cheap driving lessons" instead of your proposed "driving lessons london". Always try to use exact matches for keywords within your meta tags, otherwise why bother doing the research and picking those keywords?

Hope this helps!
