Meta Tags and Open Graph Tags: What They Do and Why They're Worth Getting Right
A page can rank perfectly and still get skipped over in search results — because the snippet shown underneath the blue link, and the preview card shown when someone shares the link, are controlled by tags entirely separate from the page's actual ranking.
The meta description tag
The meta description doesn't directly influence search ranking, but it's frequently what search engines display as the snippet under a result — meaning a vague or missing description gets an auto-generated snippet pulled from page content, which is often less compelling than something purpose-written. A clear, specific description that matches search intent tends to improve click-through rate even without changing ranking position at all.
Open Graph tags: controlling how links look when shared
Open Graph (OG) tags control how a URL appears when pasted into social platforms and messaging apps — the preview image, title, and description shown in the card. Without them, platforms fall back to guessing from page content, often picking an unrelated image or an awkwardly truncated title.
| Tag | Controls |
|---|---|
| og:title | Title shown in the share preview card |
| og:description | Description text in the share preview card |
| og:image | Preview image shown in the share card |
| og:url | The canonical URL associated with the share |
A practical writing checklist
- Keep meta descriptions around 150-160 characters — longer text tends to get truncated with an ellipsis in search results.
- Make each page's description unique — duplicate descriptions across many pages waste the opportunity and can look thin to search engines.
- Use a properly sized og:image — a common safe size is 1200×630px, which displays cleanly across most major platforms without awkward cropping.
- Match the description to actual page content — a mismatched or clickbait-y description tends to increase bounce rate, which can indirectly hurt rankings over time.
Testing before publishing
Because Open Graph previews render differently across platforms, it's worth checking how a page actually appears when shared before assuming the tags are working — a missing or malformed og:image tag is a common, easy-to-miss mistake that only becomes obvious once someone actually shares the link.
Frequently asked questions
No — it's not a direct ranking factor, but it strongly influences click-through rate from the search results page, which can indirectly affect performance over time.
Social platforms will fall back to guessing a title, description, and image from the page's visible content, which often produces a less polished or even incorrect preview card.
