Why this tiny bit of text matters
Your meta title is the blue headline people click on in Google. It also tells Google what the page is about. Keep it between 50 and 60 characters and it will not get cut off halfway through a word.
The description will not push you up the rankings, but it decides whether people click. Aim for 140 to 160 characters and talk to the person searching, not to the algorithm. Think of it as a one-line ad for your page.
Google sometimes rewrites your description if it thinks its own version fits the search better. Write a good one anyway. It is the default, and it sets the tone on every page where Google leaves it alone.
