The Meta Title is the most important part of the page for search engines. It should sum up the page’s content and theme as accurately as possible. Use one short sentence, and aim at under 55 characters to prevent Google shortening it. Rather than listing keywords, write in readable English that tells the searcher exactly what they will click through to.
The Meta Description is a short introduction to the page, sometimes called a ‘snippet’. It can be an expanded version of the page’s title and should include important keywords and make sense. Use whole sentences, not just a list of words, and 150-160 characters. It can be time-consuming to write a meta description for each page, so it is better to leave it blank, and let Google auto-create a Meta Description, rather than duplicating the text across many pages, which you may be penalised for.
