If you've ever Googled something and seen a headline and a short blurb below it — you've already experienced meta tags in action. They're among the most fundamental elements of SEO, yet they're misunderstood or neglected by a surprising number of websites. This guide explains exactly what meta tags are, why they matter, and how to write ones that improve both rankings and click-through rates.
What are meta tags?
Meta tags are snippets of HTML code that live in the <head> section of a web page — the part that visitors never see directly, but which search engines, social networks, and browsers read carefully.
Think of them as the label on a product's packaging. The product inside (your page content) is what matters most, but the label tells people — and search engines — what's inside and whether it's worth opening.
The two meta tags that directly affect your SEO performance are:
- The title tag — the clickable headline shown in Google search results
- The meta description — the short paragraph of text shown below the title
Getting these two elements right costs you nothing and can meaningfully improve both your rankings and the percentage of people who click through to your site.

The title tag is an HTML element that defines the title of a web page. In your site's code, it looks like this:
<title>Free SEO Checker — Instant Website Audit | CheckSEO</title>
This title appears in three places:
- Google search results — as the blue clickable headline
- The browser tab — so users can identify the page
- Social media link previews — when someone shares the URL (though this is often overridden by Open Graph tags)
The title tag is widely considered the most important on-page SEO element. It's one of the strongest signals Google uses to understand what a page is about, and it directly influences whether a searcher clicks on your result.
How to write a great title tag
Follow these rules for every page on your website:
Keep it between 50–60 characters
Google displays up to approximately 580 pixels of title tag text in desktop search results — which is roughly 50–60 characters. Anything beyond that gets cut off with an ellipsis. A truncated title looks unprofessional and may hide your most important words.
Put your primary keyword near the beginning
Google pays more attention to words that appear early in a title. If your page is about "SEO audits for small businesses," the title "SEO Audit for Small Businesses — Free Tool | CheckSEO" will outperform "CheckSEO — Get a Free SEO Audit for Small Businesses."
Make every title unique
Every single page on your site needs its own unique title tag. Duplicate title tags confuse Google about which page to rank and dilute the relevance signal for each one. This is one of the most common issues found in site audits.
Include your brand name at the end
Adding your brand name to the end of titles reinforces brand recognition and can improve click-through rates from users who already know you. Separate it with a pipe (|) or dash: "What is SEO? | CheckSEO"
Write for humans, not just algorithms
Your title needs to convince a real person to click it. "SEO SEO Tools SEO Checker Best SEO" may contain keywords but it will never earn a click. Write something that clearly communicates the benefit of visiting the page.
Title tag examples (good and bad)
Good title tags:
- "Free SEO Checker — Instant Website Audit | CheckSEO" (51 chars, keyword first, brand at end)
- "How to Write a Meta Description That Gets Clicked | CheckSEO" (60 chars, specific, useful)
- "SEO Audit Guide: Step-by-Step for Beginners | CheckSEO" (55 chars, clear topic, intent matched)
Bad title tags:
- "Home" (generic, no keyword)
- "CheckSEO | Free SEO Checker | SEO Audit | Website SEO | Check SEO" (too long, keyword stuffed)
- "Page 1 — CheckSEO.co.uk" (no keyword, no user value)
- "Welcome to our website! We offer great SEO services at CheckSEO" (brand buried, wasted characters)
What is a meta description?
The meta description is a short HTML attribute that provides a summary of a page's content. It appears in the page's HTML as:
<meta name="description" content="Your description here">
In Google search results, it shows up as the paragraph of grey text beneath the title — typically around 155–160 characters on desktop.
Important clarification: Meta descriptions are not a direct Google ranking factor. Google confirmed this years ago. However, they are a crucial indirect ranking factor: a compelling meta description improves your click-through rate, and higher click-through rates send positive signals that can influence rankings over time.
Google also sometimes rewrites your meta description if it doesn't think yours is the most relevant summary of the page for a given query. But a well-written description gets used verbatim far more often.
How to write a compelling meta description
Aim for 150–160 characters
Descriptions longer than 160 characters get cut off. Shorter than 120 characters leaves useful space on the table. Use every character to make the strongest possible case for clicking.
Include your target keyword
When a user's search query matches words in your meta description, Google bolds those words in the results. This makes your listing visually stand out and signals relevance to the searcher.
Lead with the most important information
Don't bury the lede. Tell people immediately what they'll get from the page. "Discover 10 free tools that will..." beats "In this guide, we will be taking a look at some tools..."
Include a call to action
Action-oriented phrases like "Learn how to...", "Find out why...", "Get your free...", "Start improving..." give users a reason to click. They subtly tell the reader what to do next.
Make every description unique
Just like title tags, every page should have its own unique meta description. Identical descriptions across pages waste the opportunity to differentiate and can look low-quality to Google.
Meta description examples
Good meta descriptions:
- "Run a free SEO audit in seconds. Check title tags, meta descriptions, images, links, and more — no sign-up required." (clear benefit, keyword present, action implied)
- "Learn how to write title tags and meta descriptions that rank higher and earn more clicks. With examples and character counts." (specific, useful, promise fulfilled)
Bad meta descriptions:
- "Welcome to our website. We provide SEO services and tools." (vague, no keyword, no value)
- "SEO, SEO tools, SEO checker, meta tags, title tags, SEO audit, website SEO, search engine optimisation" (keyword stuffed, unreadable)
- [None at all] (letting Google pick from your page content is a gamble — and Google often picks poorly)
Other important meta tags
While title tags and meta descriptions are the most impactful, there are a few other meta tags worth knowing about:
- Viewport meta tag —
<meta name="viewport" content="width=device-width, initial-scale=1">— essential for mobile-friendliness. Without it, mobile browsers scale your site down to a desktop view. - Robots meta tag — controls whether search engines index a page (
noindex) or follow its links (nofollow). Use for pages you don't want in search results, like thank-you pages or internal admin pages. - Canonical tag — tells Google which URL is the "main" version of a page when the same content exists at multiple URLs. Prevents duplicate content issues.
- Open Graph tags — control how your page looks when shared on Facebook, LinkedIn, and WhatsApp. Use
og:title,og:description, andog:image.
How to check and fix your meta tags
To manually check a page's meta tags, right-click anywhere on the page and select "View Page Source" (or press Ctrl+U in Chrome). Then search for <title> and name="description".
