Meta Tags for SEO: What They Are and How to Add Them in WordPress

Summary: Meta tags are short pieces of HTML in a page’s head section that describe the page to search engines and browsers. For SEO, two matter most: the title tag, which is the headline Google shows in results, and the meta description, the text beneath it. Others control how a page is indexed (robots), how it displays on phones (viewport) and how it looks when shared (Open Graph). In WordPress you set them per page with an SEO plugin such as Rank Math or Yoast; no code is needed.

Every page on your site has a headline and a summary that appear in Google before anyone clicks, and most business sites leave them to chance: the page title repeated, a description Google invents from the first paragraph, or nothing at all. Meta tags are where you take control of that. This guide explains what meta tags are, which ones matter, how to write the two that earn clicks, how to add them in WordPress, and how to check they are live, as part of your wider on-page SEO.

What are meta tags?

Meta tags are HTML elements placed in the head section of a web page, the part visitors never see. They tell search engines, browsers and social platforms things about the page: what it is called, what it is about, whether it should be indexed, how it should scale on a phone, which image to show when the link is shared. The two you will deal with most look like this:

<title>Boiler Repair in Preston | Same-Day, Gas Safe Engineers</title>
<meta name="description" content="Same-day boiler repair across Preston from Gas Safe engineers. Fixed-price quotes, no call-out fee. Call us 7 days a week.">

Strictly, the title is its own HTML element rather than a meta tag, but it is managed in the same place and everyone groups it with them. The same goes for the canonical tag, which is a link element. This guide follows common usage.

The meta tags that matter for SEO

Why meta tags matter

• They decide the click. The title and description are your advert in the results. Two pages ranking next to each other can see very different traffic depending on which one reads better.
• They tell Google what the page is about. The title tag is a direct relevance signal; a page titled “Home” or “Services” gives Google nothing to work with.
• They control indexing. The robots tag keeps thank-you pages, internal search results and duplicates out of search, so Google spends its attention on the pages that matter.
• They control how links look when shared. Open Graph tags are why some shared links show a crisp image and headline and others show a broken thumbnail and a URL.
• They set expectations. An accurate description brings visitors who want what the page offers, which is better for enquiries than a clever description that brings the wrong people.

How to write a title tag

• Put the target phrase near the start: “Boiler Repair in Preston” before “Same-Day, Gas Safe Engineers”.
• Say what the reader gets. A benefit, a location, a differentiator. “Boiler Repair Preston” is accurate; “Boiler Repair in Preston | Same-Day, Gas Safe Engineers” gets the click.
• Keep it to around 50 to 60 characters. Google cuts titles off at about 600 pixels wide, which is roughly that many characters; put the important words first so a cut-off title still makes sense.
• Make every title unique. Duplicate titles across pages tell Google the pages are interchangeable.
• Add the brand name at the end if there is room, separated by a pipe or hyphen. It builds recognition in results and Google often appends it anyway.
• Write it for the page, not the site. The homepage title describes the business; a service page title describes the service.
• Avoid stuffing. “Boiler Repair Preston | Boiler Repairs | Preston Boiler Engineer” reads as spam to people and to Google.

Google rewrites titles it judges poor, truncated or misleading, often using the H1 instead. A clear, honest title that matches the page is the best way to keep the one you wrote.

How to write a meta description

• Summarise what the page answers or offers in one or two plain sentences.
• Include the target phrase naturally. Google bolds words in the description that match the search, which draws the eye.
• Give a reason to choose this result: a benefit, a reassurance, a specific. “No call-out fee”, “Fixed-price quotes”, “Updated for 2026”.
• Keep it to around 155 characters. Google truncates longer ones, and on mobile sometimes shorter.
• Write a different one for every page. A site-wide description is worse than none; Google will generate one from the page instead.
• Be accurate. A description that promises what the page does not deliver earns a click and a bounce.

Google replaces descriptions it thinks are unhelpful with a snippet from the page, so the description is a suggestion rather than a guarantee. A good one is used most of the time.

Examples

How to add meta tags in WordPress

WordPress does not give you fields for the title tag or meta description out of the box. The practical answer is an SEO plugin, which adds the fields to every page and post and handles robots, canonical and social tags at the same time. Three options cover almost every site.

Rank Math

1. Plugins, Add New. Search for Rank Math SEO, install and activate. Run the setup wizard.
2. Open any page or post. The Rank Math panel sits below the editor (or in the sidebar under the Rank Math icon).
3. General tab: enter the SEO Title and Description. The preview shows how they will look in results and warns when they are too long. Set the Focus Keyword so the content analysis can check the page.
4. Advanced tab: set Robots Meta (index or noindex, follow or nofollow) and the canonical URL if the page is a deliberate duplicate.
5. Social tab: set the title, description and image used when the page is shared.
6. Site-wide defaults, including the title format with your brand name, are under Rank Math, Titles & Meta. Set them once so every page has a sensible fallback.

Yoast SEO

7. Plugins, Add New. Search for Yoast SEO, install and activate. Run the configuration wizard.
8. Open any page or post. The Yoast panel sits below the editor.
9. SEO tab: enter the SEO title and Meta description. The snippet preview shows the result and the bar turns orange when the length is off.
10. Advanced section: set whether search engines should show the page in results (index) and follow its links, and the canonical URL if needed.
11. Social tab: set the Facebook and X titles, descriptions and images.
12. Defaults are under Yoast SEO, Settings, Content types.

All in One SEO

13. Plugins, Add New. Search for All in One SEO, install and activate. Run the setup wizard.
14. Open any page or post. The AIOSEO Settings panel sits below the editor.
15. General tab: enter the Post Title and Meta Description.
16. Advanced tab: Robots Setting for indexing rules and the canonical URL.
17. Social tab: sharing title, description and image.
18. Defaults are under All in One SEO, Search Appearance.

Without a plugin

It is possible to add meta tags by editing the theme’s header.php, through a theme’s header scripts field, or with Advanced Custom Fields and a few lines of PHP. All three have the same drawback: tags added to the header apply to every page, so you get one title and one description for the whole site, which is worse than none. ACF can be made page-specific but needs a developer to wire the fields into the head. For any business site, use a plugin. Image alt text is set separately, on the image itself; see our guide to alt text.

Shopify, Squarespace and Wix

Shopify has a “Search engine listing” section at the bottom of every product, collection and page editor with title and description fields. Squarespace puts them under the page’s Settings, SEO tab. Wix has them in each page’s SEO settings panel. The writing advice above applies unchanged. Our WordPress SEO and Shopify SEO services cover both platforms.

How to check your meta tags are live

View the page source

Open the page in Chrome or Edge, right-click and choose View Page Source (or press Ctrl+U on Windows, Cmd+Option+U on a Mac). Press Ctrl+F or Cmd+F and search for <title> or name=”description”. What you see is what Google sees. In Safari, enable the Develop menu under Settings, Advanced, then choose Develop, Show Page Source.

Browser extensions

Detailed SEO Extension and SEO Minion (both free for Chrome) show the title, description, robots and canonical for the current page in one click, which is quicker than reading source.

Site crawl

Screaming Frog SEO Spider (free up to 500 URLs) lists every page’s title and description with their lengths, and flags duplicates and missing ones. For a site of any size this is the only way to find the pages you forgot.

Google Search Console

After changing tags, use the URL Inspection tool to request indexing so Google picks up the change sooner. Then watch the page’s click-through rate in the Performance report over the following weeks; a rising CTR at a steady position means the new title and description are working. Caching plugins can serve an old version of the page for a while, so if the source still shows the old tags, clear the cache before assuming the change failed.

Common meta tag mistakes

• Site-wide titles: every page called “Home | Business Name” or the business name alone.
• No description, so Google writes one from whatever text it finds.
• Titles that are the H1 repeated with nothing added.
• Keyword stuffing in titles and descriptions.
• Descriptions that promise something the page does not contain.
• A noindex left on from the development site, so the page never appears at all. Check the robots setting on any page that is missing from Google.
• Meta keywords filled in carefully for no benefit.
• Open Graph image missing, so shared links show nothing.

Meta tags and AI search

AI Overviews and AI assistants read the page, not just its tags, but the title tag is still the first thing they and every other system use to understand what a page is. A title that states the page’s subject plainly, a description that summarises its answer, and structured data that labels the page type give AI systems the same clear signals they give Google. Our guide to schema and structured data covers the third of those.

How we approach meta tags

Title and description rewrites are one of the first things we do on any new client site, because they lift clicks without waiting for rankings to move. They are included in all our SEO packages, and if you want a view of yours, we offer a free SEO audit.
