The short answer
Use the description to summarize the page's useful answer and scope. It should help someone decide whether the article matches their question, not stack synonyms or promise an outcome the page cannot deliver. Write a distinct description for each article instead of reusing a generic brand slogan.
A worked example
A fictional guide explains publication traffic estimates. 'Learn what a monthly traffic estimate does and does not tell you before comparing guest-post sites' is a relevant summary. 'Best traffic SEO authority growth cheap links' is not. The first describes a decision the article supports without suggesting a measured campaign result.
A practical checklist
- Identify the article's central answer and the intended reader. Draft one concise summary that links those two ideas in ordinary language.
- Remove unsupported superlatives, repetitive keywords and details the article does not cover. Verify that the description still matches the page after editorial changes.
- Review it beside the title to avoid repeating the same sentence. Let the title name the task while the description adds a useful boundary or next step.
What to avoid
Avoid treating a description as guaranteed search-result copy. Google may select a snippet from the page instead. Do not chase a fixed character count at the expense of clarity; concentrate on an accurate summary that remains understandable if display space is limited.
A useful follow-up
Will the meta description always appear in search?
No. It is a suggested summary; the search engine may generate a different snippet from relevant page content.
