Two pieces of text decide whether a page gets traffic from search, and both are usually written in the last five minutes before publishing. The title tag determines whether your page appears in a position where anybody could click it. The meta description determines whether they do.
They are also the two elements most often written by habit — the title becomes the page's H1 copied over, and the description becomes the first sentence of the introduction, cut off mid-clause at whatever character the limit falls on.
This is a short piece of writing with a large effect on results, and it is worth doing deliberately. Here is what each element actually does, and how to write both.
What each element actually does
The title tag is a ranking input. Words placed in it carry more weight than words buried in body copy, and it is the single strongest on-page signal you control for what a page is about. It is also the link text people see in the results.
The meta description is not a ranking input. Google has said this plainly and repeated it for years. It is a piece of advertising copy that sits directly under your link, and its only job is to give the searcher a reason to pick your result over the nine others on the screen.
This distinction has a practical consequence that people get backwards. When a page ranks at position twelve and nobody clicks, the usual instinct is to rewrite the title for rankings. More often the problem is the description: the page is visible enough, and the offer in the description is not compelling enough to beat the competition around it.
Title tag rules that hold up
Titles get truncated visually, but not at a fixed character count. Google truncates by pixel width, which means a title of narrow characters can survive longer than one full of wide capitals. Roughly, aim for a title that renders under about sixty characters, and check how it looks rather than counting letters.
- Put the distinguishing phrase first. If your title starts with a brand name, the visible part is the brand name and nothing else. Lead with the topic.
- Write the title for the page, not for the site. "Services" is not a title. "Commercial Roof Inspection in Leeds" is.
- Avoid duplicating the same phrase in the title and the H1 without adding anything. They can match, but a title that just repeats the heading wastes the one element you fully control.
- Do not stuff. Two or three keyword variants read fine. Five read like spam to a person and produce nothing for the algorithm.
- Keep the year out unless the page genuinely changes with the year. A stale "2024" in a title is worse than no year at all.
A process for writing a title
Start from the query, not from the page. Write down the phrase a person types when they want this page. Then write down what makes your page different from the other results for that phrase — a specific service area, a variant you specialise in, a constraint you handle that others do not.
Combine them in one line. The query phrase goes first, the differentiator second, the brand last and only if there is room.
Write three versions. Then read each one as if it were the only result on the page and ask whether you would click it. The version you would click is usually the one with the most specific noun in it, not the one with the most persuasive adjective.
The anatomy of a meta description
A description that earns clicks does three things in about 150 characters: it confirms the searcher is in the right place, it says something specific, and it gives a reason to choose this result.
Confirmation comes first because it prevents the wrong click. If someone searches for a term and lands on a page that turns out to be about something else, they bounce, and you have spent a visit for nothing. Repeating the query's meaning in plain words at the start of the description does the job.
Specificity is where almost every description fails. "We provide high-quality solutions for your business needs" says nothing. "Fixed-price roof inspection with a written report, booked within three working days" says three things a competitor's description probably does not.
The reason to choose is the part people omit entirely. A price, a guarantee, a turnaround, a constraint you handle — anything that functions as a distinguishing fact rather than an adjective.
Why Google rewrites your description
A significant share of the descriptions you write will never be shown. Google replaces them, usually with a snippet from the page body that matches the query more closely.
That is not a reason to stop writing them. It is a reason to write them well enough that Google has no better option. Two habits reduce the replacement rate: making sure the description's content genuinely appears on the page, and avoiding descriptions that are identical across a set of pages. When the description is clearly better than anything the page body offers as a snippet, it tends to survive.
Mistakes worth checking for
- Identical descriptions across an entire category. This is the most common problem on catalogue sites and it looks like deliberate laziness to both readers and algorithms.
- Descriptions that describe the company instead of the page.
- A call to action with no reason behind it. "Learn more!" without telling the reader what they will learn adds nothing.
- Truncation eating the point. If the useful part of the sentence is at the end, it may never be seen.
- Copy that reads as though it was written for a search engine rather than a person. Keyword strings with no sentence structure around them are a signal, and not a good one.
A worked example
Take a page selling a monthly bookkeeping service for small studios.
Before. Title: "Bookkeeping Services | Acme Accounting". Description: "Acme Accounting offers bookkeeping services for businesses of all sizes. We have years of experience and a dedicated team ready to help you with all your accounting needs."
After. Title: "Monthly Bookkeeping for Design Studios | Acme". Description: "Bookkeeping built for studios with irregular income: monthly reconciliation, quarterly tax set-aside, fixed fee from £120. Switches from your current accountant handled for you."
The second version does several things at once. The title names the audience, which is what a searcher is really scanning for. The description states a problem the audience recognises, lists what is included, gives a number, and removes a common objection. None of it is exaggerated, and all of it is checkable against the page.
Testing and iterating without thrashing
Change one element at a time, and give it enough time to produce data. Search engines take weeks to re-crawl and re-rank, and click-through rates fluctuate for reasons unrelated to your edit.
The signal worth watching is not the average position. It is the relationship between impressions and clicks on a specific query. If impressions are steady and clicks are flat, the ranking is fine and the offer is not. That is a description problem. If impressions are falling, the title is losing relevance for the query, and that is a title problem.
Keep a record of what you changed and when. Without it, you will eventually rewrite a description back to a version you already tested and rejected, which is a genuinely avoidable way to spend a month.
