Every ranking you earn comes with a free ad attached: the blue headline and the two lines of grey text underneath it. That headline is your title tag, and the grey text is your meta description. Between them they decide whether the searcher clicks you or the result above you, yet most sites treat both as an afterthought the CMS fills in automatically. This guide covers how to write each one properly, why the meta description earns its keep through clicks rather than rankings, and what to do about Google's habit of rewriting your work.
Your search snippet is a free ad
Ranking well gets you into the auction; the snippet wins the click. Two pages sitting in positions three and four can see very different traffic purely because one snippet answers the searcher's question and the other reads like a database export. That difference is measured as click-through rate, the percentage of people who see your result and click it, and it is the cheapest improvement in SEO because you already own the ranking. Nothing else on this site's list of ways to rank higher on Google pays off faster than fixing weak snippets on pages that already rank.
The two elements do different jobs. The title tag is a genuine ranking signal, one of the clearest places you tell Google what the page is about. The meta description is not a ranking factor at all, and Google has said so for years. It exists purely to persuade, which is why it belongs to copywriting as much as to on-page SEO.
Writing a title tag that earns the click
A strong page title does three things in about 50 to 60 characters: it names the topic with the keyword near the front, it adds a reason to choose this result, and it ends with the brand if there is room. Google truncates by pixel width rather than an exact character count, but titles in that range almost always display in full.
Compare "Services | Smith Plumbing" with "Emergency Plumber Brunswick: 24/7, On Time | Smith Plumbing". The first wastes the most valuable real estate on the page. The second names the service, the suburb, and two reasons to click. Write the meta title for the searcher first and the algorithm second, and avoid stuffing: one keyword phrase, placed naturally, beats three crammed together.
Run two site-wide checks while you are in there. First, hunt for duplicates: content management systems love generating identical page titles across categories, tags and paginated archives, and duplicates blur the signal for every page involved. Second, check the pattern. If every title on the site starts with your business name, the part that actually wins the click is being pushed past the truncation point on every single page. Brand goes last, not first, on everything except the homepage.

Writing a meta description that sells the click
A meta description is a two-line pitch, roughly 150 to 160 characters, and the discipline of ad copy applies. Lead with the answer or the benefit, not your company name. Mirror the words the searcher typed, because Google bolds query terms in the snippet and those bold words draw the eye. Include one concrete detail that competitors' descriptions will not have: a price range, a turnaround time, a location, a guarantee. End with a quiet call to action where it fits naturally.
The most common failure is the generic meta description: "Welcome to our website. We offer a wide range of quality services." It could belong to any business in any industry, so it persuades no one. The second most common failure is leaving the field empty, which hands Google a blank cheque to assemble whatever snippet it likes. Writing that sells without shouting is a craft, and it is the same craft we cover in our guide to SEO copywriting.
A useful habit: before you write a meta description, search the keyword and read the nine snippets you are competing against. Your job is to write the one that looks different in that exact line-up, not one that sounds good in isolation.
Why Google rewrites your meta description
Sooner or later you will notice Google showing a snippet you never wrote. This is normal: Google frequently replaces the supplied meta description with text lifted from the page when it believes that text matches the specific query better. Rewriting is common rather than rare, so plan for it instead of taking it personally.
You cannot prevent rewriting, but you can influence it. Descriptions get kept more often when they directly address the page's main search intent, accurately summarise the content, and stay within the display limit. And when Google does rewrite, it usually pulls a well-written sentence from your opening paragraphs, so a page whose first hundred words state the answer plainly tends to get a decent snippet either way. Treat a rewritten meta description as feedback: it often means the page's intent and the description's promise did not match.

Measure it: find the snippets worth fixing
Do not rewrite every page. Open the Performance report in Google Search Console, filter to queries where you rank in the top ten, and sort by impressions. Pages with high impressions, a solid position and a low click-through rate are the ones leaking traffic at the snippet. Rewrite the title tag and meta description on those pages first, wait a few weeks, and compare. Small sample sizes wobble, so judge trends rather than single days.
Two templates to steal. For a service page: keyword plus location, a differentiator, then brand. For an article: the question as the title, and a meta description that gives half the answer and promises the rest. The half-answer earns the click; the full answer on the page earns the trust.
