Copywriting is writing text meant to get the reader to do something specific, such as click, ask for information or buy. In search it works in a few places with their own rules: the title and description of each result, ads, the landing page and the call to action.
Copywriting is text written to make someone act: what it is, where it works in search, and the limits Google sets on titles and ads.
What copywriting means
In advertising, copy is the text of an ad and a copywriter is the person who writes it. The term has moved beyond classic advertising and now applies to any text with a conversion goal: a product description, an email subject line, a form button or the headline of a services page.
What sets it apart from other kinds of writing is how success is measured. An informative article has done its job if the reader understands the subject. A piece of copy has done its job if the reader takes the next step, and that step can be counted: clicks, forms sent, sales.
It is worth separating it from content marketing. Content marketing is a strategy: publishing useful content over time to attract and keep an audience. Copywriting is a way of writing that the strategy uses at specific points, for instance in an article's headline or in the call to action at the end. A team can do content marketing without a single copywriter, and write copy without having a blog.
How it works
In search, text competes in small spaces that Google partly shapes itself.
The first is the title of the result. Google calls it the title link and explains in its documentation, last updated on 10 December 2025, that it determines it automatically from several sources: the title element, the main visible title on the page, headings, the og:title tag, the text of links pointing to the page and others. The title element is a proposal, not an instruction. Google asks for titles that are unique, descriptive and concise, without keyword stuffing or boilerplate text repeated across pages.
The second is the excerpt underneath, the snippet. According to Google's documentation, last updated on 20 April 2026, snippets are created mainly from the page content, and Google sometimes uses the meta description when it describes the page more accurately than the page text itself. There is no length limit on a meta description, but the snippet is truncated in results as needed.
The third is search ads. According to Google Ads Help, a responsive search ad takes between 3 and 15 headlines of up to 30 characters and between 2 and 4 descriptions of up to 90 characters. Google Ads combines these texts and learns which combinations perform best, so every headline has to make sense next to any other.
The fourth is the landing page, where the person arrives after the click. Its text has to deliver what the title or the ad promised. At the end comes the call to action, the button or link where the page's goal comes together.

Four places for one message, and at three of them Google has a say.
Why it matters
In these spaces every word takes up scarce room. An ad headline has 30 characters and a description 90. Whatever does not fit there, nobody sees.
The text also decides whether the click is worth anything. A title that promises more than the page offers can bring in visits, but people who arrive and do not find what was promised leave. For a business, that is paid or earned traffic that brings neither sales nor leads.
And part of it is out of the copywriter's hands. Google can rewrite the title and choose a different snippet if it judges that the proposed text does not describe the page well. Copywriting for search therefore writes for two readers at once: the person deciding whether to click and the system deciding which text to show.
Best practices
Write a different title for each page that says in a few words what it is about.
Write the meta description as a summary of the page, not as a list of keywords.
In responsive search ads, write headlines that work in any order and combination.
Make the landing page deliver the promise of the title or ad in the first visible block.
Phrase the call to action with a concrete verb and a single goal per page.
Compare versions with A/B tests rather than deciding by taste.
Common mistakes
Repeating the same title on many pages and changing only one detail.
Filling titles and descriptions with keywords.
Promising something in the ad that the landing page does not offer.
Writing ad headlines that only make sense in a fixed order.
Crediting a rise in conversions to new copy without comparing it with the old version.
Confusing copywriting with content marketing and judging sales copy by reading time.

A technical audit covers this and everything else in one pass.
Copywriters write text with a measurable goal: headlines, ads, product descriptions, sales pages, emails or calls to action. In digital marketing they usually work closely with the people running SEO and ads, because these texts have space limits and their results are measured in clicks and conversions.
How is copywriting different from content marketing?
Content marketing is a strategy for attracting and keeping an audience with useful content over time. Copywriting is a way of writing aimed at getting the reader to act. The two meet at specific points, such as an article's headline or the call to action at its end.
How many characters does a responsive search ad have?
According to Google Ads Help, each headline allows up to 30 characters and each description up to 90. You enter between 3 and 15 headlines and between 2 and 4 descriptions, and Google Ads combines them. The path fields of the display URL allow up to 15 characters each.
Does Google use the title and meta description I write?
Not always. Google determines the title of a search result automatically from several sources, and the title element is only one of them. The snippet comes mainly from the page content; Google uses the meta description when it describes the page more accurately. Both can be influenced, not fixed.
How do you know whether copy works?
By comparing it with another version under the same conditions. An A/B test shows two versions to similar audiences and measures which one gets more clicks or conversions. In responsive search ads, Google Ads does something similar with combinations of headlines and descriptions. Without a comparison, a rise may be down to the season or the budget.
