How long should a title tag be?

There is no character limit, which is why the usual advice to stay under 60 characters is unreliable. Google truncates by rendered pixel width, roughly 600 pixels on desktop. A title of 62 narrow characters can survive while 55 wide ones get cut. This tool measures the actual width of your text in Google's font, so the preview cuts where Google will.

Why does the character counter disagree with the preview?

Because they measure different things and the pixel one is the one that decides. The character count is shown because people are used to thinking in it, but if the two disagree, trust the preview and the pixel budget.

How long should the meta description be?

Long enough to be worth reading and short enough to survive. Around 150 to 160 characters is the usual guidance, and the pixel budget here is a better guide. Descriptions much under 70 characters often get replaced by Google's own snippet from the page body.

Does the meta description affect ranking?

Not directly. It affects whether somebody clicks, which is the point. Google also rewrites descriptions often, particularly when the query does not match what you wrote, so treat it as your best offer rather than a guarantee.

Do I need both og: and twitter: tags?

Mostly not. X falls back to the Open Graph tags when the twitter: ones are missing, so og:title, og:description and og:image cover almost everything. The twitter:card tag is worth keeping, since it decides between a small thumbnail and a large image.

Why is my og:image not showing?

Nearly always one of three things: the URL is relative rather than absolute, the image is behind auth or a firewall the crawler cannot reach, or the platform has cached an older version. Each platform has its own debugger that forces a refetch.

Are these pixel limits official?

No. Google has never published them and changes them without notice. The values here are observed and approximate, which is why the tool shows the measured width next to the budget rather than a pass or fail badge.

Checks

2 to fix

No title. Google will invent one from the page content.
No description. Google will pull a snippet from the page instead, and it is rarely the sentence you would have chosen.
No og:image. Shares will render as a bare text link on X, LinkedIn and Slack.
No canonical. Add one if this page is reachable at more than one address.
