7 common Google Ads mistakes for webshops (and how to avoid them)

Google Ads is a powerful channel for webshops that want to grow. Used well, ads can bring a steady stream of visitors who buy. Yet many business owners see little result from their campaigns. That is usually not because Google doesn't work, but because it is used the wrong way.

This article covers seven common mistakes that many webshops make with Google Ads. These mistakes waste budget, miss opportunities and cause frustration. By recognising them and tackling them deliberately, the return on Google Ads goes up considerably.

1. Setting up campaigns without a strategy

Without a clear strategy it quickly becomes guesswork. Many webshops start their campaign with a few random keywords, set a daily budget and wait for results. The problem is that there is nothing to hold on to. What should be achieved? Who is the target audience? And through which type of campaign?

Without goals it is impossible to measure whether a campaign is successful. Decisions are then made ad hoc, usually on gut feeling instead of data. This leads to unpredictable results and little room to grow.

Solution: always start with the end goal. Do you want new customers, higher revenue, or to encourage repeat purchases? Choose the right campaign structure, targeting, bidding strategy and ad content based on that.

2. Putting everything in one campaign

A classic mistake: throwing everything into one campaign. Different products, audiences, regions and keywords are combined to go live quickly. That makes it impossible to analyse which parts perform. The result is that money is spent on poorly performing parts without anyone seeing it.

If the structure of your campaigns is wrong, optimising becomes almost impossible. Even smart adjustments such as bidding strategies or A/B tests then deliver little, because the underlying data is not reliable.

Solution: work with separate campaigns per product group, brand, audience or margin class. This gives insight and control. With a good structure, budget can be moved to what works, and wasteful parts are found sooner.

3. A poor or missing product feed

For webshops that advertise with Google Shopping, a good product feed is crucial. Yet it is often pulled automatically from the CMS without further optimisation. The result: incomplete titles, wrong categories or products that are even disapproved.

A weak feed means fewer impressions, lower click-through rates and worse quality scores. That translates into higher costs per click and fewer sales.

Solution: use tools such as Channable to optimise the product feed. Make sure titles contain clear keywords, descriptions are complete and the right Google categories are used. Also keep the feed up to date, so that Google and potential customers always see the right information.

4. Steering on clicks instead of sales

A high click-through rate is nice, but says little about the success of a campaign. In the end, webshops are about sales, not visitors. Yet many campaigns are still judged on clicks or impressions.

This leads to misplaced satisfaction. Campaigns seem to do well based on CTR or CPC, while revenue lags behind. Without conversion data it is impossible to steer on return.

Solution: set up conversion tracking properly, including measuring order values. Steer campaigns on ROAS instead of traffic. Only then does it become clear which campaigns contribute to profit growth.

5. Using the wrong keywords

Keywords are the foundation of a successful search campaign. Yet they are often chosen without enough research. People gamble on high-volume terms without looking at relevance or search intent. As a result, ads are shown to visitors who have no intention of buying.

A common problem is the lack of negative keywords. As a result, ads appear on irrelevant or even harmful searches. This leads to unnecessary costs and confusion among the target audience.

Solution: use tools such as Google Keyword Planner and look mainly at search intent. Exclude irrelevant terms straight away. Check the search terms report every week and add new exclusions to improve the quality of the traffic.

6. Not optimising landing pages for mobile

Most webshop visits now happen on mobile. Yet many landing pages are still not well suited to it. Pages load too slowly, buttons are too close together and information is hard to read. That makes people drop off before anything is bought.

Without a good mobile experience, even the best campaigns underperform. Google also looks at user experience as part of the quality score. A poor mobile page can therefore lead to higher click prices too.

Solution: test landing pages thoroughly on mobile devices. Make sure they load fast, have a clear layout, clear calls to action and intuitive navigation. Adjust ads if mobile traffic turns out to have different needs than desktop visitors.

7. Not maintaining campaigns

A common mistake is forgetting maintenance. Campaigns are set up, run for months without analysis and are only adjusted when the budget is almost gone. Optimisation moments are lost, while small adjustments can often have a big impact.

A campaign is alive. Competition changes, search volume fluctuates and consumer behaviour shifts. Without regular evaluation, opportunities are missed and costs become higher than necessary.

Solution: schedule fixed evaluation moments. Analyse performance per campaign, ad group, keyword and device. Test ads, adjust bidding strategies and look critically at the search terms report. Make it a fixed process, not an occasional action.

Getting more out of Google Ads

Google Ads is not a simple tool, but anyone who uses it well builds a profitable and scalable acquisition machine. Webshops that avoid the mistakes above lay the foundation for campaigns that deliver not just clicks, but revenue and growth.

By investing in structure, strategy and optimisation, Google Ads becomes a source of lasting growth. Not tomorrow, but in a way that pays off better month after month.
