Meta Tags SEO

Meta tags are HTML elements in the <head> that give search engines instructions about a page, such as whether to index it or how to display it in results.

If you have ever assumed every meta tag boosts ranking or that meta keywords still matters, you are optimising for a rule that no longer applies.

Key points

  • Place title and meta description in every page's <head>; they are the most important meta tags for SEO.
  • Use meta robots to control indexing: noindex prevents a page from appearing in search results.
  • Avoid meta keywords; Google ignores it, and it wastes time and space.
  • Keep meta description unique per page and relevant to the content; Google may rewrite it if it is not.
  • Check viewport meta tag for mobile usability; it is not a ranking factor but affects user experience.
  • Do not duplicate title across pages; each page needs a distinct title that reflects its content.

The same meta description, different treatment

A product page with a generic meta description 'Buy the product' was often rewritten by Google to show a snippet from the page content. After changing the meta description to include specific details ('Buy the 2024 running shoes in blue and black'), Google started using it in 70% of search results. The change took two weeks to appear across all queries.

Three meta tags that matter most

  • Title tag Defines the page title shown in search results and browser tabs. It is a strong ranking signal and should be unique, descriptive, and under 60 characters. A good seo title generator can help craft effective titles.
  • Meta description Provides a short summary that may appear as the snippet under the title. Write a compelling, relevant description for each page; Google may rewrite it if it is not.
  • Meta robots Controls whether a page can be indexed (noindex) or whether links can be followed (nofollow). Incorrect settings can block entire sections from search results.

Three mistakes that waste your effort

  • Using meta keywords Google has not used meta keywords as a ranking signal for years. Adding it still wastes bytes and does not help the page appear for those terms.
  • Duplicating meta descriptions Reusing the same meta description across many pages tells Google nothing about each page's unique value. Write distinct descriptions that match the content.
  • Ignoring metadata purpose Confusing what is metadata seo with all meta tags can lead to over-optimising irrelevant ones. Focus on tags that affect indexing and display.

Three things to check regularly

  • Robots rules Verify that meta robots does not accidentally noindex important pages. Use Google Search Console to spot blocking errors that hurt crawlability.
  • Meta description uniqueness Run a crawl to find pages with missing or duplicate meta descriptions. Each page should have a custom description that reflects its specific content.
  • Viewport settings The viewport meta tag controls how a page scales on mobile devices. An incorrect or missing viewport can break mobile usability, though it is not a direct ranking factor.
