5 practical examples of bad advertising

There are great examples in the world of advertising, as well as failures that provide lessons. Google Ads is no exception, where small errors can have a significant impact on campaign performance.

Here are five practical examples of bad adverts, with comments to help you understand why they didn’t work:

Advertising text too general

Example: an advert offering “The best gifts for every occasion!”

Comment: This kind of advertising is too general and does not target a specific audience or meet a specific need. It can be difficult for users to understand what exactly is being advertised and why they should click on that particular ad.

Inaccurate targeting

Example: an advertisement for men’s sports shoes appearing on a fitness website for women.

Comment: Inaccurate targeting leads to advertising reaching the wrong audience. In this case, the likelihood of the ad being clicked on is very low because it does not match the viewer’s interests.

A complex and confusing call to action

Example: an advertisement containing a CTA: “Get yours by signing up, downloading and following!”.

Comment: Too many steps in the call to action can confuse the visitor. Using a clear and simple CTA increases the likelihood that the user will take the desired step.

Absence of negative keywords

Example: a children’s store that uses the keyword “toys” but does not include negative keywords such as “adults”.

Comment: Without negative keywords, the ad may appear in searches that are not relevant to the target audience. This leads to waste of budget and reduces the overall effectiveness of the campaign.

Low quality score

Example: an ad that redirects the user to an unrelated landing page.

Comment: If an advertisement takes the user to a page that does not match the search query or the content of the advertisement, this will negatively affect the quality score. A low quality score means higher costs and lower placement in advertising.

Illustrative example of a promotional visual

Before you go any further, make your own bet – guess what service this ad offers? 😄 “Look at the picture”

It’s a given: a strikingly beautiful image, a compelling call to action, a few words here and there.

Comment: a confusing puzzle! Is it an advertisement for a luxury apartment, designer furniture or perhaps new parquet flooring? Who would bother to click on this ad? Perhaps those who are simply driven by curiosity, but certainly not those who are actually being targeted. And is there a specific target group in mind? Just think how much advertising budget can be wiped out by such a mess.

Solution: advertising must be like a well-conducted symphony – every note and pause in place. There must be an attractive and contextual image, the text of the ad must be sufficiently informative (respecting the ad’s length limits) and the call to action must be clear and elicit the desired action.

Oh, I almost forgot – we are talking about an accounting firm 🙂

A new approach: imagine an advertisement with a wonderful image that grabs your attention from the first glance: a calculator and an elegant pen, both placed on a shiny table next to a euro sign drawn in fine buttermilk foam. The text says: “Know the power of your numbers.” And underneath the call to action: ‘Discover how our accounting services can take your business to the next level. Find out more now!”

The new approach leaves no room for confusion. It’s targeted, it’s clear and it’s appealing. Not only will it attract the right target audience, but it will also let them know straight away what they are getting – a professional accounting service that brings clarity and growth to their business.
