Table of content

    Google Ads is a powerful tool that can drive significant traffic and increase conversions for your business. However, many agencies make mistakes that can undermine the effectiveness of your campaigns and waste your budget. As Bofu Marketing Agency, we've identified ten common mistakes Google Ads agencies make and we offer tips on how to avoid them.

    1. Not setting clear goals

    Before starting any Google Ads campaign , it is crucial to define clear objectives. Without specific goals, it's difficult to measure the success of your campaigns or optimize your ads for better results.

    To set effective goals, consider the following questions:

    • What is the goal of this campaign?
    • What action do you want users to take after seeing your ad?
    • How will you measure the success of this campaign?

    2. Ignoring Optimization for Mobile Devices

    The use of smartphones is constantly increasing. Ignoring optimization for mobile devices can therefore cause you to miss a significant portion of your target audience. Make sure your ads and website are optimized for mobile devices to maximize your reach and conversions.

    3. Using too many generic keywords

    Using keywords that are too generic can lead to unqualified traffic and increase your costs without increasing conversions. Instead, focus on keywords that are more specific and relevant to your business. Use tools like SEMrush or Ahrefs to find long tail keywords that can help you target more qualified customers.

    4. Not using ad extensions

    Ad extensions allow you to display additional information about your business, such as your address, phone number, or links to specific pages on your website . They can help improve your ad's visibility and encourage clicks. Not using ad extensions is a missed opportunity to improve the performance of your campaigns.

    5. Ignoring Negative Keywords

    Negative keywords are keywords that you don't want your ads to show for. Ignoring negative keywords can lead to unwanted impressions and clicks, which can waste your budget and decrease the quality of your traffic.

    6. Not Tracking Conversions

    Not tracking conversions is one of the biggest mistakes you can make. Without conversion tracking, it's impossible to know which ads, keywords, or landing pages are performing best. Make sure you set up accurate conversion tracking to effectively optimize your campaigns.

    7. Ignore low-performing ads

    It's important to regularly monitor the performance of your ads and disable any that aren't performing well. Ignoring low-performing ads can waste your budget and reduce the effectiveness of your campaigns.

    8. Not Optimizing Landing Pages

    Landing page optimization is key to maximizing conversions. Make sure your landing pages are relevant to your ads, easy to navigate, and call-to-action. To learn more about the importance of landing pages, check out our article on Advertising on Google: How does it work?

    9. Not adjusting bids based on geographic location

    Adjusting your bids based on geographic location can help you target your ads more effectively and maximize your ROI. For example, if you find that your conversions are higher in certain regions, it might be a good idea to raise your bids for those specific placements.

    10. Not testing different ad formats

    It's important to experiment with different ad formats to see which ones work best for your business . Google Ads offers several ad formats, such as text ads, display ads, and video ads. Experiment with different formats to find the ones that generate the best results for your business.
