What is Google Ads?

Google Ads is Google's advertising platform. It runs on a PPC (pay-per-click) model: you only pay when someone clicks. Through a keyword auction system, your ads appear at the top of the search results at the right moment.

What is Google Ads?

Google Ads, formerly Google AdWords, is Google's online advertising platform. Launched in 2000, it lets a business show targeted ads to people who are actively searching for its products or services. It is the cornerstone of what is called SEA (Search Engine Advertising), advertising on search engines.

The principle is simple: you choose keywords related to your activity, you write ads, and they appear when someone types a matching search. You operate on a pay-per-click (PPC) basis, which means showing the ad is free and you only pay when someone actually clicks.

Ads are not limited to search results. They can also appear on Google's network of partner sites, on YouTube, in Gmail or in mobile apps, depending on the campaign type you choose. Unlike organic search, which takes time, Google Ads delivers almost instant visibility.

The benefits for businesses

If Google Ads has won over businesses of every size, it is because it combines speed, precision and measurement. Its main strengths:

• Immediate visibility: you appear at the top of the results as soon as the campaign is live, without waiting months.
• Precise targeting: you show ads based on the query, location, device, time of day or audience profile.
• Controlled costs: you set a daily budget and only pay per click, which makes spending easy to steer.
• Measurable results: every click, conversion and euro spent is trackable, which lets you calculate a real return on investment.
• Complementary to SEO: Google Ads fills the gaps on competitive keywords or launches a new product while organic search builds up.

It is one building block among others in an overall strategy. To place SEA within the full set of acquisition channels, see our guide to web marketing.

How the auction and Quality Score work

Many people think the spot at the top of the results goes to the highest bidder. That is false. For every search, Google runs a real-time auction that plays out in a fraction of a second, and the bid amount is only one factor among several.

An ad's position depends on its Ad Rank, which mainly combines:

• The bid: the maximum amount you are willing to pay for a click.
• The Quality Score: a relevance rating calculated from the expected click-through rate, how well the ad matches the keyword, and the quality of the landing page.
• Extensions and formats: the extra information (links, phone number, reviews) that enrich the ad.

The consequence is important: a well-built ad, with a high Quality Score, can rank above a competitor who bids more, while paying less per click. Quality pays, in the literal sense.

The campaign types

Google Ads is not just sponsored links. The platform offers several formats, to choose according to your objective:

• Search: the text ads shown at the top of Google's results. Ideal for capturing an active purchase intent.
• Display: visual banners shown across the network of partner sites. Perfect for brand awareness and remarketing.
• Shopping: product listings with photo, price and merchant, at the top of the results. The reflex of e-commerce.
• Video (YouTube): ads before or during videos, to tell a story and reach a wide audience.
• App: campaigns dedicated to promoting mobile apps across Search, Play, YouTube and Display.
• Performance Max: an automated campaign that shows ads across all Google channels from a single objective and creative assets, driven by Google's AI.

Getting a first campaign off to a good start

Launching a Google Ads campaign takes method. The main steps:

1. Define a clear objective: traffic, lead generation, sales or brand awareness. Everything else follows from it.
2. Run keyword research: identify the relevant queries, assess their volume and competition, then organise them into thematic ad groups.
3. Write strong ads: compelling headlines, a clear promise, a call to action, extensions, and above all a consistent landing page.
4. Set budget and bids: a controlled daily budget and a fitting bidding strategy (maximise clicks, target CPA, target ROAS).
5. Set up conversion tracking: without measurement, optimising is impossible. This is the step too many advertisers neglect.

The first few weeks are a learning phase: performance stabilises as you refine keywords, exclude useless queries and adjust bids. This is precisely where expertise makes the difference. Frenchsquid is Google Ads certified (Search and Measurement), which ensures rigorous management of campaigns and of their measurement.

Finally, keep in mind that SEA does not replace deep, lasting visibility. To last in Google's results as well as in AI answers, also think about GEO, AI search optimization, and more broadly about the reasons to have a high-performing website for your business.
