Common errors when running Google Ads and how to fix them
Not setting clear goals
When starting an advertising campaign, if you do not set clear goals, it will be difficult to create high efficiency. Clearly defining advertising goals will help you orient the advertising strategy to be deployed, and set KPIs on the achieved effectiveness to monitor, measure and optimize the campaign. Determine exactly what you want to achieve through advertising on Google to create appropriate campaigns to achieve the set goals. Make sure to set a goal throughout the campaign to help the advertising implementation process go smoothly.
Choosing the wrong keywords
Keywords are one of the important factors that make up the success of a Google Ads campaign. Because it is the bridge between the target customers and your business's advertising. Choosing the wrong keywords causes the ad to be displayed to people who are not interested or have no need for the product or service. This not only causes businesses to miss out on real potential customers but also wastes budget and time.
Common mistakes businesses make when choosing keywords include choosing keywords that are too broad or too narrow, or advertising too many keywords, making it difficult to reach target customers. Advertising too many keywords means that no keyword receives good impressions because the ad is displayed for a series of search queries. To avoid wasting time, money and effort, create separate campaigns for different keyword groups. Using keywords that are not related to the product or service will not only make the advertising campaign ineffective but also waste the budget. Therefore, businesses need to avoid these mistakes and should know how to use keywords more wisely.
To do that, businesses should spend time researching target customers and competitors. By understanding the target audience, you will be able to orient the appropriate keywords that are relevant to solve the problems that customers are facing. In addition, you should research and analyze competitors to learn and create a suitable set of keywords. Use keyword research tools such as Google Keyword Planner, Ahrefs, and Semrush, ... When setting up an advertising campaign on Google, you should choose long keywords with low competition. This is to optimize Google ads to achieve the best results and improve conversion rates.
Do not use negative keywords
Negative keywords are keywords that can prevent ads from being displayed to users when they are searching. Not using negative keywords can cause ads to be displayed to people who do not need the product or service or do not intend to buy, wasting budget and reducing the effectiveness of the campaign. To fix this, identify irrelevant keywords that you do not want your ads to display. Then add these keywords to the negative keyword list in the ad. Adding negative keywords will help increase ad quality score, reduce costs and increase ROI.
Unattractive, inappropriate ad content
One of the common mistakes when running Google Ads that many businesses often make is creating unattractive, inappropriate ad content. Keywords and ad content are important factors that determine the effectiveness of the campaign. Content is the factor that attracts, and retains customers in the ad and increases the likelihood of clicking on the landing page to learn more about the product or service.
If the content is not attractive enough and does not solve the problems that customers encounter, they will leave immediately. This not only affects the performance of the campaign, the quality score and the visibility of the ad on Google. Common errors related to ad content such as attaching a phone number to the content directly violate the platform's policies. There are many punctuation errors or special characters in the ad text, font errors, etc. Ads that do not contain keywords or lack extensions: page links, captions, calls, locations, prices, customer forms, etc., or incomplete content all create bad experiences for users when clicking.
Poor Landing Page Quality
The Landing Page is the last place users visit after clicking on an ad. If a business wants to increase the conversion rate for advertising and create attractive content, optimizing the landing page is essential. This helps businesses increase the chance of converting visitors into customers. Some common landing page errors include ads directing users to a non-functional landing page, content on the landing page is not relevant to the ad. Poor website loading speed causes users to waste time and data when loading. Content on the landing page is incomplete, unattractive, and lacks a call to action.
When encountering this error, you can handle it by optimizing the landing page by redesigning the interface to be eye-catching and user-friendly. Optimize the page loading speed and landing page content to ensure relevance to the ad. Provide full information on the landing page, especially contact information, which should be placed in an easy-to-see position. Don't forget to add a clear call-to-action button to convince users to click. All of this will bring customers a great experience and increase the advertising conversion rate.
The daily advertising budget is too high
To maintain the operation of the advertising campaign and help businesses achieve their goals, the advertising budget is a very important factor. Setting an inappropriate budget such as too low or too high will have a negative impact on the advertising campaign. Many people when running ads do not set a spending limit for the budget, causing the ad to always be in a state of distributing all the budget. If you do not know how to optimize, the ad will not only not achieve the desired effect but also waste the budget. Especially the problem of click fraud and fake clicks is ongoing and there is no thorough solution.
Bidding too low
The bid is the amount you are willing to pay for each click on the customer's ad. If you bid too low compared to your competitors, your ads will have difficulty competing and the chance of being displayed in good positions is gone. Or you may have to pay a higher cost to be displayed without achieving the desired results. Instead, you should have a suitable bidding strategy for your ads. You can rely on Google's recommendations and choose a smart bidding strategy to achieve the set goals. Don't forget to test different options to make the most of the data and optimize your bidding strategy.
Not monitoring, measuring and optimizing ads regularly
Monitoring and measuring the effectiveness of your campaign is a very important factor when running ads on Google. Especially in the context of increasing competition, increasing advertising costs along with changes in algorithms and advertising policies of search engines. This requires businesses to regularly measure, analyze and evaluate the results of Google Ads campaigns continuously combined with updating algorithms and policies. Based on the collected data to optimize advertising campaigns on Google to achieve the best results, improve business efficiency.
Thus, through the above sharing, you have learned the common mistakes when running Google Ads that need to be avoided and the appropriate remedies. Hopefully, this useful knowledge will help you gain more skills and experience to successfully deploy advertising campaigns on Google to achieve the highest efficiency!
Frequently Asked Questions

You've searched for a keyword and Google has shown your ad multiple times before without you clicking on it. The daily budget for the ad has run out, or the ad has a low quality score, or the Google Ads account is being viewed, causing the ad to be suspended.
When you see your ad is rejected due to an inactive landing page. At this point, you need to check factors such as whether the landing page is active.
