Quick answer. Search ads show your ad when someone types a keyword you bid on. An auction decides who appears and in what order, based on your bid and ad quality. You pay when someone clicks. Use search to capture people who are already looking for what you sell, then send them to a page that matches what they searched.

<p>Search ads are the text ads you see at the top of Google or Yandex when you type something in. Someone is looking for a product or a fix, and you pay to show up at that exact moment. That is the whole magic. You are not interrupting people. You are answering a question they already asked.</p>

<p>I hire media buyers, and search is usually the first channel I want a junior to understand. It is the cleanest way to learn intent, keywords, and auctions without drowning in creative work. Get this right and the rest of paid marketing makes more sense.</p>

How do search ads actually work?

Three things drive search ads: keywords, the auction, and intent. Let me take them one at a time.

Keywords are the words you want to show up for. Someone types buy running shoes online, and if you bid on that phrase, you can appear. You do not pick one word. You build a list of phrases that real buyers type.

The auction happens every single time someone searches. Google and Yandex look at everyone bidding on that query and rank the ads. Your position depends on two things: how much you are willing to pay per click, and how relevant your ad and landing page are. This relevance score is called Quality Score in Google. A higher score means you can pay less and still rank above a competitor who bids more. So a sloppy ad with a big budget often loses to a tight ad with a smaller one.

Intent is why search converts so well. There is a big difference between someone typing what are running shoes and someone typing nike pegasus 41 size 10 price. The first person is curious. The second is reaching for a wallet. You want to spend on the second type and be careful with the first.

When should you use search ads?

Use search when there is existing demand. People are already typing your category into the box. Your job is to be there when they do.

  • You sell something people search for by name. Software, plumbers, flights, courses, legal help. If there is a search query, there is a chance.
  • You need leads or sales now, not awareness later. Search captures demand that already exists, so it tends to pay back faster than channels that create demand.
  • You can measure a clear action. A purchase, a form, a call. Search rewards you for knowing exactly what a conversion is worth to you.

Search is weaker when nobody knows your category exists yet. If you invented something brand new, very few people are searching for it, so there is little demand to capture. In that case you start with social to create demand first, then search picks up the people who go looking afterward.

What does a basic campaign structure look like?

Both Google Ads and Yandex Direct use the same shape: account, then campaigns, then ad groups, then keywords and ads. Keep it simple at the start.

  • Campaign: set by budget and goal. One campaign for your main product line is plenty when you begin. Budget and targeting live here.
  • Ad group: one tight theme per group. If you sell shoes, you might have one ad group for running shoes and another for hiking boots. Do not mix them.
  • Keywords: a small list of phrases that match the theme of that group. Tight groups let you write ads that match the search word for word.
  • Ads: at least two or three per group so the system can test them. The headline should echo the keyword. If they searched running shoes, the word running shoes should be in the headline.

One more piece: match types. A keyword can be broad, phrase, or exact. Broad shows you for loosely related searches and eats budget fast. When you are learning, start with phrase and exact match so you control what triggers your ad, and add negative keywords (words you never want to show for, like free or jobs) as you see junk in your search terms report.

What mistakes do beginners always make?

I see the same ones over and over. None of them are clever. All of them cost money.

  • Sending all clicks to the homepage. If someone searched for a specific product, send them to that product page. The homepage makes them hunt, and they leave.
  • Ignoring negative keywords. Without them you pay for searches like free, diy, or unrelated terms. Read your search terms report every few days and cut the waste.
  • Bidding on one word. Single words like shoes are broad, expensive, and full of browsers. Longer phrases cost less and convert better.
  • Judging too early. Five clicks tell you nothing. Wait for enough conversions, or at least enough clicks, before you change bids or pause anything.
  • Tracking nothing. If conversion tracking is not set up, you are guessing. Set up the conversion before you spend a cent.

Here is the mindset I want you to keep: your results are yours. The auction is the same for everyone. If you are losing, fix your keywords, your ad text, and your landing page. Those are the parts you control.

Key takeaways

  • Search ads capture existing demand: people who are already searching for what you sell.
  • The auction rewards relevance, so tight keywords, matching ad text, and a good landing page can beat a bigger budget.
  • Set up conversion tracking and negative keywords before you scale, and judge results on conversions, not clicks.

Frequently asked questions

How much do search ads cost?
You pay per click, and the price depends on competition for your keywords. A click can be a few cents in a quiet niche or many dollars in lawyers or insurance. Start with a small daily budget you can afford to lose while you learn, then scale once you see conversions pay back.
What is the difference between Google Ads and Yandex Direct?
They work the same way: keywords, auctions, and pay per click. The main difference is reach. Google dominates most of the world, while Yandex is strong in Russia and a few nearby markets. Pick the engine your customers actually use, and the skills transfer either way.
What is Quality Score and why does it matter?
Quality Score is Google's rating of how relevant your keyword, ad, and landing page are. A higher score lets you rank above competitors while paying less per click. You raise it by matching your ad text to the keyword and sending traffic to a page that delivers what the search promised.
How long before search ads work?
You can see clicks on day one, but real signal takes time. Give it enough clicks and conversions to judge fairly, often a couple of weeks for a small budget. Resist daily changes. Let data build, read your search terms, then adjust keywords and bids based on what converts.
