Answer in brief
PPC, or contextual, advertising is an ad shown in answer to a search query or next to matching content and paid for only when someone clicks. Each impression is decided by an automatic auction that weighs the bid together with the quality of the ad and of the page it leads to. The advertiser sets the queries, the text, the page and the budget; the auction sets the price of each click.
A paid ad shown in answer to a query, charged by the click
A business owner who asks what is ppc advertising usually means the lines marked as ads above the search results. The letters stand for pay-per-click, which Wikipedia defines as an online advertising model in which advertisers pay a publisher each time a user clicks on an ad. Google Ads Help explains it with a billboard, priced by how many people might drive past. Online, if a hundred people see your ad and three click, you pay for three clicks.
In Russian-speaking markets the same thing is called contextual advertising, and the name describes the other half: how the ad is chosen. Yandex Ads, the advertising service of the Yandex search engine, defines it as ads shown on the basis of people’s previous actions online, by algorithms that analyse the context of a page or a user’s interests. It separates two kinds. Search advertising answers a query directly; thematic advertising follows behaviour and fits into the site a person is reading.
Where the ads appear: search results and partner networks
Google Ads Help describes two territories. On the Search Network, ads can appear above or below the results on Google Search and beside results on the Shopping tab, Google Images and Google Maps. Search partners, other search sites that carry these ads, are included by default in a new Search campaign and can be switched off. The Display Network reaches people as they browse millions of websites and apps and Google’s own properties such as YouTube and Gmail.
Yandex Direct is built the same way. Yandex Ads lists its placements as Yandex search, the Yandex Advertising Network, Yandex Maps and two galleries on the search page. The network is described as a large set of partner sites, apps, Telegram channels and blogs that works from interests and behaviour. In the two simplified launch modes, ads go to search and the network at once, and impressions cannot be divided between them.
How the auction picks the ad and sets the price of a click
Nobody sells positions from a price list. Google Ads Help says an auction takes place every time someone searches on Google or visits a site that shows ads. It names six main factors: the bid, the quality of the ads and the landing page, the expected impact of extras such as a phone number, minimum quality thresholds, the context of the search, and the competitiveness of the auction. Together they produce Ad Rank, the values that decide whether an ad may show and where, calculated again for every search.
The bid is a ceiling, not a price. Google’s definition of actual cost-per-click says you pay only what is minimally required to clear the Ad Rank thresholds and beat the competitor immediately below you. Higher quality ads, the help pages add, can often lead to lower costs per click. The figure advertisers watch, Quality Score, is a diagnostic from 1 to 10 built on expected clickthrough rate, ad relevance and landing page experience. Google says plainly that it is not an input in the auction.
Yandex describes the same logic in its own words. Click prices are not fixed, so an auction decides which ads to show, weighing their relevance and how much the advertiser is ready to pay, while the user’s page is loading. On the thematic sites of the advertising network, the Yandex Direct training course explains, the click price is set by the bid of the nearest competitor. In Yandex search, ads are ranked by a combination of the bid, quality indicators and a click forecast for that impression.
What a campaign is made of: queries, ads, a page, a budget, a goal
Google Ads Help describes an account in three layers. The account holds the login and billing details; campaigns have their own budget and the settings that determine where ads appear; ad groups contain similar ads and their keywords. Keywords are the words or phrases used to match ads with what people search for. Yandex Ads lists the same parts for Direct: key phrases, targeting by location, device and interests, the ads, the auction, landing pages and analytics.
Two parts are forgotten most often. The first is the page the click lands on: Yandex notes that ads lead either to the advertiser’s site or to specially built landing pages that persuade the visitor to register, buy or subscribe. The second is the count of those actions, which Google calls a conversion: an ad click that leads directly to behaviour valuable to you, such as a purchase, a sign-up or a phone call. The budget closes the list, a daily average in Google Ads and a daily or weekly limit in Direct.
What the advertiser decides and what the system decides for them
The advertiser’s side is larger than it looks. You choose the queries you want and the ones you refuse, write the texts, pick the page, the region and the devices, and set the ceiling for a click. Google Ads Help stresses that a bid can be changed at any time. Yandex says the same about money: the entrepreneur sets the budget, although there is a minimum threshold for launching a campaign.
The other side belongs to the system and to competitors. The price of each click and the position come out of the auction. Even the daily spend is not exact: Google Ads Help explains that a campaign may exceed its average daily budget, up to twice that budget in a day and 30.4 times that budget in a month for most campaigns. Even the look is partly automatic: Yandex selects a layout template for each ad, and Google assembles display ads from the headlines and images you upload.
How paid clicks differ from SEO and from social targeting
Search engines keep the two kinds of results apart. Google Ads Help says ads are matched by how closely the search fits your keywords and ordered by a combination of bid and relevance, while ordinary results are matched by the text on a page and the links to it, independently of Google’s advertising programmes. Yandex Ads compares the two by time. Ads bring first results after launch and are shown only while the campaign runs. SEO takes several months, keeps bringing visitors when the work stops, and carries no guarantee of the first page.
Payment does not separate targeted ads in social networks from all this: Wikipedia notes that Facebook, Instagram, LinkedIn, TikTok and others also charge per click. The difference is the signal. A search ad answers words a person has just typed, which Yandex calls demand that has already formed. A targeted ad is chosen by who the person is and what they follow, so it reaches people who were not looking. What people already search for starts with search ads; what nobody knows to look for needs the other kind.
Where a small budget drains: broad queries, the home page, no goal
The first leak is wide queries. Google Ads Help says broad match is the default type assigned to every keyword, so an unedited list reaches far more searches than its owner pictures. The remedy is a list of refusals. Google’s example is an optometrist selling eyeglasses who adds negative keywords for wine glasses; Yandex’s is a subscription online cinema that advertises on ‘watch films’ and excludes the word ‘free’. Yandex also warns against the opposite excess: an overlong exclusion list cuts impressions and slows the algorithms’ learning.
The second leak is the destination. Landing page experience is defined by Google as how relevant and useful the page is to people who click the ad, and a home page makes the visitor hunt for the advertised offer. The third leak is a campaign with nothing to count. Without a goal the report shows clicks, and clicks are a cost, not a result. Yandex says as much about its own budget forecast: the tool predicts only the price of clicks, not the cost of conversions and sales.
What to prepare before the first campaign and when to hand it over
Preparation fits on one sheet. Write the single offer the campaign will sell and the page that repeats it. List the queries a buyer would type and, beside them, the words that mark someone who is not a buyer. Name the action that counts as a result, a request, a call or a purchase, and make sure it is recorded. Decide the monthly sum you are ready to spend on learning whether this works. Then the question shifts from what is ppc advertising to which of these queries deserve the money.
Running it yourself is realistic with one service, one region and time every week to read which searches triggered the ads. Yandex describes a simplified launch mode for users with no experience. Hand the work over when there are several services or regions, when the page has to be rebuilt first, when goals and analytics are not connected, or when nobody has hours for the constant adjustments that Yandex itself says the channel requires. A studio such as VITON13 Studio takes this on as campaign management, and the same sheet serves as the brief.
Practical checklist
- Write one offer and one landing page that repeats the promise of the ad in the same words.
- List the queries a buyer types and add negative keywords for the lookalike searches you do not serve.
- Set up conversion tracking for the request, call or purchase before the first click is paid for.
- Set a daily budget you can sustain for a month and compare the real spend with it every week.
- Check weekly which searches actually triggered the ads and exclude the ones that bring no buyers.
Questions and answers
Is PPC advertising the same as contextual advertising?
They describe one thing from two sides. Pay-per-click names the payment model: money is charged for a click. Contextual names the way an ad is chosen: by a search query or by the content and interests around a page. In Russian-speaking markets the second term is the usual one for campaigns in Google Ads and Yandex Direct.
Does the highest bid always win the first ad position?
No. Google Ads Help lists the bid as one of six auction factors, next to the quality of the ad and of the landing page, and says a relevant ad can win a higher position than a competitor who bids more. Yandex ranks search ads by the bid together with quality indicators and a click forecast.
Do I pay my full bid for every click on the ad?
Usually less. By Google’s definition of actual cost-per-click, the charge is the minimum needed to clear the quality thresholds and stay above the competitor below, and the bid is only the ceiling. Google adds that the ceiling can be exceeded when bid adjustments or its enhanced bidding option are switched on.
Can a campaign spend more than the daily budget I set?
In Google Ads it can, within limits. The help pages say spend may pass the average daily budget on busy days, up to twice that amount for most campaigns, while a month is capped at 30.4 times the daily figure. In Yandex Direct you set a daily or weekly limit on a balance that is topped up in advance.
How fast do paid search ads work compared with SEO?
Yandex Ads puts it this way for small and medium businesses: ads give the first results after the campaign starts, SEO after several months. The trade-off is duration. Ads are shown only while the campaign is paid for, and visitors from search keep arriving after the optimisation work has stopped.
