E-commerce: how to run a successful campaign with Google Adwords

Location is a determining factor in a physical store's sales flow. Similarly, for an e-commerce business, ranking well in search engines is crucial to gaining visibility and consequently attracting more customers. In other words, the better your Google ranking, the better your revenue.

AdWords is a system that offers different types of paid ads highlighted on Google search pages. It works like an auction where the bid amount, keyword, and ad quality determine the address's positioning in sponsored results.

When creating a paid ad, you can choose the campaign's initial bid. There's no exact amount to invest, but in e-commerce, it's recommended not to start with a very low bid, as the online platform is your workspace and the only way to reach customers. Typically, the higher the investment, the higher the return.

Campaign performance can be tracked in real time through various metrics available on the AdWords platform, such as click-through, conversion, and bounce rates. Campaign effectiveness begins to be measured from the moment a user types a keyword until they perform, or fail to perform, the action expected by the advertiser. Keeping an eye on these metrics is essential for optimizing future campaigns and better positioning yourself against your competitors.

Putting together a good campaign

Google AdWords displays your ads based on keyword searches and their relevance. Choosing the right keyword is the most important factor in differentiating an ad, and relevance can also be determined by the amount paid and search volume. The higher the search volume for a keyword, the better the ad's ranking.

A good keyword should be as specific as possible to differentiate itself from competitors in general searches. However, terms should contain no more than ten words to avoid the risk of becoming overly broad. Long-tail keywords are always preferable, but it's important to know how to use them. The right limit will ensure your ad reaches the right audience—those most likely to be genuinely interested in the brand or company—after all, that's what they were searching for.

With Adwords, targeting this audience is simple, as it allows you to target sponsored links based on geographic location, device, and language.

How to use Adwords

To advertise with AdWords, you need to create an account on the platform, enter your email address, and link the website of the company you're targeting. This way, ads will run in the chosen region, and billing will be made in the currency of the contracting party's country. Payment can be made by credit card, debit card, or bank slip. Then, simply set up the campaign and choose the bid amount per search. You can also choose the automatic bidding option, where the system sets the most appropriate daily budget for the campaign.

FAQ

What is the minimum recommended investment for Google Ads?

For most niches, an initial media budget of R$1.500 to R$3.000 per month allows for sufficient data collection for optimization. Highly competitive niches (law, healthcare, real estate) require more. The important thing is to start with a budget that allows for learning without compromising cash flow.

How long does it take for campaigns to generate results?

Well-structured campaigns generate initial leads within 48-72 hours. The optimization phase lasts 30 to 60 days, during which the algorithm learns which keywords, times, and audiences convert best. From the second month onwards, the cost per lead tends to decrease consistently.

What is ROAS and how do I know if my campaign is performing well?

ROAS (Return on Ad Spend) is the revenue generated divided by the amount invested in ads. A ROAS of 4x means R$4 in revenue for every R$1 invested. A healthy ROAS varies by niche, but in general, any result above 3x is considered positive for e-commerce.

What is the difference between Google Ads and Meta Ads (Facebook/Instagram)?

Google Ads captures existing demand — people who are already searching. Meta Ads creates demand — it interrupts users who weren't looking. In general, Google Ads converts better for products/services with high purchase intent, while Meta is ideal for awareness and the top of the funnel.

My ad is showing up but I'm not getting any clicks. What could be the problem?

Generally, the problem stems from: unattractive ad copy, an offer lacking a clear differentiator, a lack of ad extensions, a historically low CTR affecting Ad Rank, or overly broad targeting reaching an unqualified audience. An audit identifies the exact bottleneck.
