Meta Tags

What are meta tags?

Meta tags are HTML elements placed in the head section of a web page. They are invisible to visitors but read by search engines and social networks to understand and display the content of your page. They are the information Google shows in its search results: the clickable blue title and the grey description underneath.

Google has moved on and no longer uses every type of meta tag for ranking, but some of them remain essential for SEO and for your click-through rate in the search results.

The meta tags that matter for SEO

The title tag is the most important meta tag of all. It is the clickable blue title in Google's results. It directly influences both ranking and click-through rate (CTR). Best practice: 60 characters maximum (beyond that Google truncates it), include the main keyword at the start of the title, and be both descriptive and inviting. For example, "Plumber Lyon | 24/7 Emergency Callout - Free Quote" works better than "Home - Plomberie Martin SARL".

The meta description is the grey text under the title in Google's results. It is not a direct ranking factor, but it strongly influences your CTR. A good meta description runs to 155 characters maximum, contains the main keyword (which appears in bold in the results), and includes a call to action (Discover, Get your free quote). A high CTR sends Google a positive signal.

The robots tag tells search engines whether to index the page (index/noindex) and whether to follow its links (follow/nofollow). Useful for excluding private pages, thank you pages or duplicates.

The canonical tag tells Google which version of a page is the original when the same content exists at several URLs. Essential for avoiding duplicate content, which dilutes your SEO.

Open Graph tags for social networks

The Open Graph tags (og:title, og:description, og:image) control how your page previews when it is shared on Facebook, LinkedIn, WhatsApp and so on. Without them, social networks generate a random preview, usually an unappealing one. With them, you control the title, the description and the image shown. The ideal OG image is 1200x630 pixels.

Twitter Cards (twitter:card, twitter:title, twitter:description, twitter:image) do the same job for Twitter/X. They produce rich previews that lift the click-through rate on everything you share.

The most common meta tag mistakes

Duplicate titles: every page needs a unique title. Plenty of sites use the same one everywhere ("Welcome to our website"), which stops Google telling the pages apart. Missing meta descriptions: without one, Google pulls a random snippet from your content, and it is rarely appealing.

Titles that are too long or too short: a 10 character title has no keywords, a 100 character title gets cut off. Aim for 50 to 60 characters. Meta descriptions with no pull: "We are a plumbing company" invites nobody to click. "Plumber available 24/7 in Lyon. On site within 30 minutes. Free quote" makes people want to click.

How to manage your meta tags with Next.js

Next.js provides a built in metadata system that makes meta tags easy to manage. In each page you export a metadata object with the title, the description and the Open Graph tags. Next.js then generates the matching HTML tags automatically. It is more reliable and more maintainable than inserting tags by hand.

Meta tags and structured data: two complementary layers

A common misconception is that meta tags are enough for Google to understand your page properly. In reality they describe the page on the surface, while structured data (Schema.org, in JSON-LD format) describes precisely what the content means: is it a product, a review, a local business, an FAQ, an article?

For a small business, combining the two is powerful. A compelling title tag improves the click, while LocalBusiness markup (name, address, opening hours, phone) and Review markup (star rating) enrich how you appear in the results. A yellow star or opening hours shown directly in Google can lift the click-through rate by 20 to 30% compared with a bare result.

Writing a title and a description that convert

The title tag is not only a keyword exercise, it is a sales line. A good title often follows the structure: service + area + point of difference. For example, "Electrician Nantes | Available 7 days a week, quote in 24h" combines the trade, the town and two concrete promises.

For the description, think like your customer: which objection should it answer, which benefit should it lead with, which action should it ask for? A description that covers those three questions stands out on a crowded results page. A small example: an accountancy practice that replaced "Chartered accountants in Bordeaux" with "Chartered accountant in Bordeaux: first meeting free, answer within 48h, specialists for small businesses and freelancers" saw its CTR go from 2.4% to 4.3%.

Meta tags checklist for a small business

- A unique title on every page, under 60 characters, keyword first. - A meta description under 155 characters with a call to action. - Open Graph tags with a well made 1200x630 image. - A canonical tag on pages with similar or duplicate content. - A "noindex" robots tag on thank you pages and drafts. - Regular checks with Google Search Console or Screaming Frog.

Best practice in 2026

In 2026, Google still rewrites titles and descriptions often, depending on the query, but well considered tags remain the starting point for its choice. The rise of rich results and AI generated answers makes structured markup even more strategic: what is clearly described stands a better chance of being cited. For a small business, the minimum effort (a good title, a good description, local Schema) offers one of the best returns in SEO.
