How Google Ads Works

Query, search term and keyword are three different things

The vocabulary trips people up before the mechanics do, and the confusion costs money. A query is what the person typed. Google calls that same thing a search term once it appears in your reporting: "a word or set of words a person enters when searching". A keyword is different — "a word or set of words that Google Ads advertisers can add to a given ad group". It is your guess at what they would type.

The gap between the guess and the reality is where budget disappears, and Google gives you the bridge: the search terms report. It states plainly that "depending on your keyword matching options, the search terms listed might be different from your keyword list". Two things to know about that report. It is a sample, not a ledger — terms without enough query activity are omitted for privacy. And reading it is not an optimisation task you do once; it is the ongoing job.

What each layer of an account actually controls

Google organises an account into three layers, and knowing which lever sits where prevents most pointless arguments. In Google's words: "Google Ads is organized into three layers: account, campaigns, and ad groups." The account holds the email, password and billing. Campaigns "have their own budget and settings that determine where your ads appear". Ad groups "contain a set of similar ads and keywords".

The practical consequence: budget is a campaign decision, not an ad group one, so if you want to protect spend on one product line it needs its own campaign. And because an ad group holds both the keywords and the adverts, keeping groups tight is what lets the advert actually answer the search rather than describe the company in general.

An auction, not a price list

Position is not bought. Google describes Ad Rank as a score based on six factors: your bid, the quality of your ads and landing page, the Ad Rank thresholds, the competitiveness of the auction, the context of the person's search, and the expected impact of your assets and formats. It also states that Ad Rank "is calculated every time a user does a search and is recalculated for different positions on the search results page".

So there is no permanent position to buy, and anyone offering one is selling something Google does not sell. Google is explicit about this even where it publishes bid estimates: "meeting or exceeding these estimates isn't a guarantee of ad placement". Final placement, it says, still depends on competition, your Ad Rank, your budget and account settings, and user behaviour.

What a daily budget actually does

A daily budget is an average, not a ceiling, and this is the single most common billing surprise. Google documents that on a given day "your campaign might spend up to twice your average daily budget to take advantage of fluctuations of traffic", and that "at the end of the month, you will have spent no more than 30.4 times your average daily budget". The 30.4 is just the average number of days in a month.

There is a real protection underneath. If serving overshoots the limit, Google states "you'll never pay more than these two limits" and that "Google will cover the difference". The useful habit is therefore to think in months: decide the monthly figure you are willing to spend, divide it by 30.4, and stop reading individual days as though they were a problem.

What counts as a result is your decision, not the platform’s

Google defines a conversion action as "a specific customer activity that is valuable to your business" — and the advertiser chooses which activities those are. It measures them from four sources: website actions, app actions, phone calls, and offline conversions imported back in. For many Malaysian businesses the genuine enquiry is a phone call or a WhatsApp message rather than a form, and if nobody set that up it will simply not be in the numbers.

Two mechanics decide whether the reports make sense. Primary conversion actions feed bidding and the "Conversions" column; secondary ones are, in Google's words, "for observation only" and report into "All conversions" without influencing bidding. And a conversion window sets how long after a click something still counts. Google's default click-through window is 30 days, and it can be set from one day up to 30, 60 or 90 depending on the conversion source. A considered purchase that completes outside that window is not missing; it was never going to be counted.

Why two reports disagree

When the platform's number and your own records differ, the cause is usually structural rather than a fault. Different conversion windows count different periods. Primary and secondary actions land in different columns. Analytics attributes a session differently from how Google Ads attributes a click. And the search terms report omits low-volume searches by design.

The way through is not to reconcile them to the digit but to decide which number answers which question, write that down once, and keep three things separate in every report: what the platform recorded, what your team confirmed was a real enquiry, and what remains genuinely uncertain. A report that collapses those three into one figure is easier to read and worth less.

What Google will and will not let you advertise

Google's advertising policies cover four broad areas: prohibited content, which you cannot advertise at all; prohibited practices, things you cannot do as an advertiser; restricted content and features, which you can advertise with limitations; and editorial and technical standards for the ads, websites and apps themselves. A disapproved ad "won't be able to run until the policy violation is fixed and the ad is reviewed".

Repeat violations escalate on a published ladder, and the ladder is per policy: a warning first, then a three-day account hold on the first strike, a seven-day hold on the second, and suspension on the third. Each step requires violating the same policy again within 90 days of the previous one, and an account can receive at most one warning and three strikes per policy. During a hold the account cannot run ads, though you keep access to it and to the reports. If you operate in a restricted category — health, finance, anything adjacent to gambling — this is the part worth understanding before the first campaign rather than after a hold.

Buying ads does not change your organic ranking

This gets sold in both directions, so it is worth quoting. Google answers it directly: "Does buying ads improve my search ranking? No. Google's advertising programs are independent of our search results." Its own advertiser-facing material puts it the same way — a pay-per-click solution "won't improve your organic search rankings".

The two channels do help each other, just not mechanically. Paid search produces evidence within weeks about which searches turn into real enquiries, and that makes the slower, compounding work of search visibility far better targeted. What it never does is move an unpaid listing up the page.

What to do next

If you are deciding whether to start: write down one outcome you would genuinely pay for, and check that something on your website lets a stranger complete it. If you already have an account: open the search terms report before anything else, because it tells you what you actually bought last month. If the numbers are the problem, start with the conversion actions rather than the bidding — almost every unreadable ads report traces back to what was, or was not, defined as a result.

The depth on Search campaigns specifically — matching, exclusions, advert assets and the budget mechanics above — sits on Google Search Ads.
