Meta Tags for Search and Social Shares
Write a title, description, canonical URL, and Open Graph tags before you publish a page.

Title and description
Keep the title near 60 characters and the description near 160 so search results are less likely to cut them off. Describe the page, not the whole website.
The canonical URL should be the one address you want indexed. Use it for the Open Graph URL as well.
Social image
Add an absolute image URL for Open Graph and Twitter. A large summary card needs a wide image. Paste the generated tags into the page head, then check a share preview before the campaign goes out.
