When someone sees your result in a list, they read the title first and the description second. If both say the same thing, you waste half the space.

Give each a different job

The title names the page and states its topic. The description adds a reason to click: what the page covers, who it suits or what the reader will be able to do. For a guide on 404 pages, the title might be "404 Pages That Help Visitors". The description could then add: "Covers the right status code, a short message and links that keep people on your site."

Read them together. Copy the title and description into a text file and read them as a reader. Is there repetition? Is a question left unanswered? Does the pair make a promise the page keeps?

Audit the whole site

Use a crawler to export titles and descriptions into a spreadsheet. Sort to find duplicates, missing descriptions and titles that are far too long. Add columns for page importance and fix the top pages first.

Handle templates carefully. Automatically generated titles, such as "Post title | Site name", are fine. Automatic descriptions made from the first words of the text are often poor. For key pages, write them by hand.

Special page types

Category pages, tool pages and the home page each need a title and description that describe their role, not a copy of an article.

Check the real result. Search for "site:yourdomain.com" plus a distinctive word to see how a page appears. Remember that Google can rewrite either part. If it often does, make the originals more precise.

Example pairs

Page: a guide to robots.txt mistakes. Title: "Common robots.txt Mistakes and How to Fix Them". Description: "Check for a full-site block, blocked CSS files and conflicting rules, with examples of each fix."

Page: an image compressor tool. Title: "Image Compressor and WebP Converter". Description: "Shrink JPEG and PNG files in your browser and save them as WebP. Adjust quality and compare sizes."

Each pair names the page and then adds a specific detail.

When to rewrite and when to leave alone

Rewrite when a page gets many impressions but few clicks, when the pair repeats itself, or when the page changed. Leave alone a page that performs well. Do not rewrite every title on a site at once, because you will lose the ability to tell which change helped.

Pairs for different page types

Guide: title "How to Fix Broken Links on a Website", description "Find 404 errors with a crawler and Search Console, then choose between a redirect, a corrected link or removal."

Tool: title "Word and Keyword Counter", description "Count words, characters and repeated phrases in your text, with the results shown as you type."

Category: title "Image Optimisation Guides", description "Guides to choosing formats, sizing images and compressing them for faster pages."

Notice that the title names the page and the description adds the detail. Neither repeats the other.

A review routine

Every quarter, export your titles and descriptions and sort by clicks. Look at pages with many impressions and a low click-through rate, and rewrite the pair for those first. Look at pages with no description. Look at pairs that read like the page they sit next to. Record the date of each change so you can compare results later.

Keep a record. Store the final versions in your content system, not only in a spreadsheet, so they survive redesigns.
