SEO Optimisation and Meta Tags: A Practical Guide
Meta tags are snippets of HTML that provide information about a webpage. Some help search engines understand or manage a page, while others influence how it appears when shared online. Used correctly, they can support a well-optimised website—but they are only one part of SEO.
What are meta tags?
Meta tags are usually placed inside the <head> section of a webpage’s HTML. Visitors generally do not see them on the page itself, although some—such as the title tag and meta description—may appear in search results.
Different tags serve different purposes. Some describe a page, some give instructions to search-engine crawlers, and others help browsers display content correctly.
Important meta tags for SEO
Title tag
The title tag gives a page its title in browser tabs and may be used as the clickable heading in search results. It is not technically a meta tag, but it is often discussed alongside them because it is an important on-page SEO element.
Write a distinct, accurate title for every important page. Keep it concise, put the main subject near the beginning where it reads naturally, and avoid repeating keywords unnaturally. Search engines may rewrite titles when they think another version better matches a search.

Meta description
A meta description summarises a page. Search engines may use it as the descriptive text beneath a result, but they can also create a snippet from the page itself. A description is not a direct ranking factor, yet a clear and useful one may encourage people to choose your result.
Summarise what the page offers, make the wording specific, and give each page its own description. There is no guaranteed ideal character count: the amount shown can vary by device and search query.
<meta name="description" content="Explore reliable plants for shady gardens, with practical advice on choosing, planting and caring for them.">
Robots meta tag
The robots meta tag can tell search engines whether a page may be indexed and whether its links may be followed. For example, the following directive asks compliant crawlers not to index a page:
<meta name="robots" content="noindex, follow">
Use indexing directives carefully. A mistaken noindex on an important page can remove it from search results. If a page must be kept out of search, check that the directive is present in the rendered page and that the crawler can access it.
Viewport tag
The viewport tag helps browsers display a page appropriately on mobile devices. It is not a ranking shortcut, but a mobile-friendly experience is an important part of a usable website.
<meta name="viewport" content="width=device-width, initial-scale=1">
Canonical tag
A canonical tag indicates which URL should be treated as the preferred version when similar or duplicate pages are available. It is an HTML link element rather than a meta tag, but it is commonly included in discussions about SEO metadata.
<link rel="canonical" href="https://example.com/garden-plants">
Canonical tags are signals, not absolute commands. Use a valid, consistent URL and avoid pointing unrelated pages to the same canonical address.
Social sharing tags
Open Graph tags can control the title, description and image shown when a page is shared on many social platforms. X (formerly Twitter) also supports its own card tags. These tags do not directly improve organic rankings, but they can help shared links look clear and appealing.
<meta property="og:title" content="A Guide to Plants for Shady Gardens">
<meta property="og:description" content="Find suitable plants and learn how to care for them in low-light spaces.">
<meta property="og:image" content="https://example.com/images/shady-garden.jpg">
<meta property="og:url" content="https://example.com/garden-plants">
<meta property="og:type" content="article">
What about the meta keywords tag?
The meta keywords tag was once used to list terms related to a page. Major search engines, including Google, do not use it as a ranking signal. Adding a long list of keywords is therefore unlikely to help SEO. Focus instead on useful content that addresses the subject and the reader’s needs.
Best practices for meta tags
- Write unique titles and descriptions for important pages.
- Describe the page accurately rather than promising something it does not deliver.
- Use natural language instead of cramming in keywords.
- Check that important pages are not accidentally marked
noindex. - Use canonical URLs consistently where duplicate or similar pages exist.
- Preview social sharing tags and make sure image URLs work.
- Review tags after major site changes, and test them with suitable SEO tools.
Meta tags are only one part of SEO
Well-written metadata can make pages easier to understand and present them more effectively in search results and social shares. However, it cannot make up for thin or unhelpful content, poor site structure, slow performance, or a difficult mobile experience. The best results come from combining accurate metadata with useful pages, clear navigation and sound technical SEO.

What is the meta title tag for SEO?
The meta title tag, more commonly called the title tag, specifies a webpage’s title and may appear as the clickable headline in search results and in a browser tab. For SEO, it helps search engines and visitors understand what the page is about, so write a unique, accurate and concise title for each important page, including its main topic naturally. Search engines may display a different title if they consider it more relevant to a user’s search.
What meta tags should I use for SEO?
For SEO, use a unique, descriptive title tag and meta description on each important page, as these can help searchers understand your content and may encourage clicks from search results. Add a robots meta tag only when you need to control whether a page is indexed, and use a canonical link element to indicate the preferred URL for duplicate or very similar pages. A viewport tag supports a good mobile experience, while Open Graph tags can improve how your pages appear when shared on social media. Avoid the meta keywords tag: major search engines do not use it for rankings.
Are meta tags still relevant?
Yes, meta tags are still relevant, but their importance depends on the tag. Title tags help describe a page and can influence how it appears in search results, while meta descriptions may encourage people to click, even though they are not a direct ranking factor and search engines may rewrite them. Robots tags can guide search engines on whether to index a page, and social metadata can improve how links appear when shared. Meta keywords, however, are generally ignored by major search engines. Focus on accurate, useful tags—and remember that they support, rather than replace, high-quality content and good technical SEO.
What are the tags for SEO optimization?
The main tags used for SEO optimisation include the title tag, which gives a page its search-result headline, and the meta description, which summarises its content. The robots meta tag can guide search engines on whether to index a page, while the viewport tag helps pages display properly on mobile devices. Canonical tags help identify a preferred URL when similar pages exist, and Open Graph tags control how links appear when shared on social media. Each tag should be accurate and relevant; meta keywords are no longer used as a ranking factor by major search engines.
How do I optimize SEO tags?
To optimise SEO tags, write a unique, accurate title tag and meta description for each important page, using relevant search terms naturally and explaining clearly what the page offers. Keep titles and descriptions concise, avoid keyword stuffing, and check that each page has the correct indexing settings and canonical URL. Review how your pages appear in search results, but remember that search engines may rewrite titles or descriptions, and that useful content and a good user experience matter just as much as tags.
What is meta tag in SEO with example?
A meta tag is a piece of information in a webpage’s HTML that helps describe the page or tell search engines how to handle it. For example, a meta description summarises the page and may appear beneath its title in search results: <meta name="description" content="Discover practical tips for improving your website’s SEO.">. Meta descriptions do not directly determine rankings, but a clear, relevant summary can help people decide whether to visit your page.
How do meta tags affect SEO?
Meta tags help search engines understand and present information about a webpage, but their impact on rankings varies. A well-written title tag can clarify a page’s topic, while a useful meta description may encourage people to click a search result, although search engines can choose to show different text and descriptions are not a direct ranking factor. Robots directives can affect whether a page is indexed, and canonical tags can help indicate the preferred version of a URL. Meta tags work best alongside helpful content, a technically sound website and a good user experience.
Does metadata help SEO?
Yes, metadata can support SEO by helping search engines understand a page and by shaping how it appears in search results and social shares. A clear title tag and relevant meta description may encourage people to click, although meta descriptions are not a direct ranking factor and search engines may choose different text for a result. Metadata works best alongside useful content, a well-structured website and good technical SEO.
