Meta tags don't change what your page does — they change how it's described to search engines, and how it looks when someone shares your link on social media. Getting them wrong doesn't break your site, but it does mean your link shows up looking worse than it should, or not at all in a preview.
Why Title Tags Get Cut Off
Google doesn't enforce a strict character limit on your title tag — it truncates based on pixel width, since wider characters like "W" take up more room than narrow ones like "i". As a rough rule of thumb, titles display fully up to about 60 characters, and meta descriptions up to about 155-160 characters, before an ellipsis appears. This is why a live character counter is more useful than a fixed cutoff: two titles with the same character count can render differently depending on which letters they use.
Open Graph vs. Twitter Cards
Open Graph tags (the ones prefixed og:) were introduced by Facebook and have since become the de facto standard that most platforms — Slack, LinkedIn, Discord, iMessage — read to build a link preview. Twitter/X maintains its own separate tag set, prefixed twitter:, but it falls back to your Open Graph tags for anything Twitter-specific that's missing. That fallback behavior is exactly why most sites include both tag sets rather than picking just one: it costs almost nothing and covers every platform.
twitter:card to summary_large_image whenever you have an og:image — it renders a much bigger, more clickable preview image than the small-thumbnail default "summary" card.
Why Your Preview Has No Image
A missing or broken social preview image almost always traces back to the og:image tag pointing at the wrong thing. It needs to be a direct, publicly accessible URL to the actual image file — not a link to a webpage that happens to contain the image, and not a path that requires login to view. If that URL 404s, redirects unexpectedly, or points to something too small, most platforms just fall back to showing no image, or a generic site icon instead.
Meta Tags and Search Rankings
It's a common misconception that filling in meta tags improves your ranking directly. It doesn't — these tags control presentation, not ranking. A well-written title and description can meaningfully improve click-through rate once your page is already showing up in results, because they're often the deciding factor between two similar-looking listings. But whether your page ranks at all comes down to different signals entirely: content quality, backlinks, site authority, and technical factors unrelated to what your meta tags say.

FAQ
How long should a title tag and meta description be? A title tag displays fully up to roughly 60 characters before Google truncates it with an ellipsis; a meta description has room for roughly 155-160 characters. Both limits are approximate, based on pixel width rather than a strict character count, which is why a live counter is more useful than a hard cutoff.
What's the difference between Open Graph tags and Twitter Card tags? Open Graph tags (prefixed og:) were introduced by Facebook and are now the general standard most platforms read when generating a link preview. Twitter Card tags are Twitter/X's own separate tag set; Twitter falls back to Open Graph tags for any Twitter-specific tag that's missing, which is why sites often include both rather than just one.
Do I need an og:image for the preview to show an image? Yes — without an og:image tag pointing to a real, accessible image URL, most platforms will show a link preview with no image at all, or fall back to a generic site icon. The image should be a direct URL to the actual image file, not a webpage.
Will pasting these tags into my site guarantee good search rankings? No — these tags control how your page is described and previewed, not how it ranks. Good title tags and descriptions can improve click-through rate once your page already appears in results, but ranking itself depends on many other factors like content quality, backlinks, and site authority.
