Google Ads Campaign Optimisation: A Step-by-Step Guide
In today's fast-changing world of online marketing, Google Ads campaign optimisation has become not just desirable but essential for business success. Managing ad campaigns effectively requires not only understanding how the Google Ads platform works, but also constantly adjusting and improving your strategy in response to market dynamics and audience preferences.
From competitor analysis, through selecting and excluding the right keywords, to budget management and planning future activity, every aspect of a Google Ads campaign demands a thoughtful approach and ongoing attention. In this article, we'll walk through the key steps and strategies that will help maximise the effectiveness of your Google Ads campaigns, delivering a better return on investment and greater visibility for your brand online.
Why Is It Worth Optimising Your Google Ads Account?
Google Ads account optimisation is key to the success of any online ad campaign. There are several reasons why we should regularly pay attention to this aspect of digital marketing.
- Increasing ROI (return on investment): Optimising your Google Ads campaigns lets you make better use of your ad budget. Through precise targeting, eliminating the wrong keywords and improving ad quality, you can increase the number of conversions while lowering costs, and earn more as a result!
- Better understanding of your audience: Regular optimisation gives you deeper insight into the needs and behaviour of your potential customers. Analysing campaign data helps identify the most effective keywords, target groups and ad formats.
- Competitive advantage: The online world is dynamic and always full of competition. By constantly optimising campaigns, you can keep pace with, or even get ahead of, competitors, adapting your strategies to current trends and changing consumer preferences.
- Better-quality traffic to your site: Google Ads campaign optimisation helps attract more relevant traffic to your site. This means visitors are more interested in your offer, which increases the chances of conversion.
- Adapting to Google's changing algorithms: Google regularly updates its algorithms, affecting how ads are shown and ranked. By optimising your Google Ads account, you can make sure your campaigns stay in line with the latest guidelines and best practices.
- Increasing brand visibility: Properly optimised Google Ads campaigns don't just drive conversion traffic, they also build brand awareness. Using the right keywords and targeting the right market segments helps achieve greater visibility.
How Often Should You Optimise Google Ads Campaigns?
The frequency of Google Ads campaign optimisation should be balanced, to keep your activity effective while avoiding the negative effects of frequent major changes, which can push the Google algorithm back into a re-learning phase. Here are a few key points to keep in mind:
- Caution with major changes: It's important that major campaign changes, such as significant budget modifications, changing your bidding strategy or a thorough overhaul of keywords, are made carefully. These changes can effectively “reset” the algorithm's learning process, which can temporarily affect campaign performance. It's advisable to make this type of change carefully and not too often, unless campaign data clearly points to a need for immediate action.
- Regular, small-scale optimisation: Rather than rare, large changes, it's better to make smaller adjustments on a regular basis. These include, for example, minor bid tweaks, adding or removing individual keywords, and small changes to ad copy. This type of optimisation can be carried out more often, depending on market dynamics and the specifics of your industry.
- Analysing results: Regularly analysing results is essential. It's advisable to review campaign data at least once a week to understand which elements are working well and which need improvement. This kind of analysis lets you respond quickly to changing market conditions and user behaviour, without needing to make radical changes.
- Seasonal and occasion-based changes: In some industries, where clear seasonal or occasion-based patterns can be observed, optimisation may call for more dynamic changes. In these cases, it's important to plan and implement these changes with enough lead time, allowing for a possible algorithm learning period.
Analysing and Assessing Competitor Activity in Google Ads

Analysing and assessing competitor activity is a key part of your Google Ads marketing strategy. It lets you understand the market, identify gaps and opportunities, and adjust your own activity to make it more effective. Here's how to use tools such as SEMrush, Senuto, Google Keyword Planner, Google Trends and the Google Ads Transparency Center to analyse your competitors:
- SEMrush: This all-in-one tool offers competitor research features, including keyword analysis, backlink analysis and ad copy analysis. SEMrush gives you detailed insight into a competitor's advertising strategy, including the keywords they use, their ad spend and the performance of individual campaigns.
- Senuto: A tool focused on SEO and content marketing, which can also be used to analyse competitors in Google Ads. Senuto lets you track competing sites' rankings in search results and analyse their keyword strategy, which can provide valuable pointers for optimising your own campaigns.
- Google Keyword Planner: This free tool from Google lets you identify popular keywords and understand how competitive they are. You can use it to see which keywords your competitors are using effectively, which can help you adjust your own keyword strategy.
- Google Trends: This free tool lets you analyse search trends on Google, which can be useful for understanding broader market trends and consumer interests. This makes it easier to adapt your ad campaigns to current user preferences.
- Google Ads Transparency Center (adstransparency.google.com): This platform lets you browse the ads currently being shown by Google Ads advertisers. It gives you a direct view of the ads your competitors are running, which can provide valuable insight into their advertising strategy and creative approach.
- Taking market feedback and trends into account: Tracking market trends and analysing customer feedback can provide valuable pointers on the direction of optimisation. Sometimes subtle shifts in consumer preferences call for small but strategic adjustments to a campaign.
Adjusting Bids and Analysing Results in Google Ads
Since Google Ads is an auction system where you compete with other advertisers, you need to pay proper attention to bid adjustments and result analysis in Google Ads. Here are a few tips on how to manage these:
1. Adjusting Bids in Google Ads:
- Set your initial bids based on campaign goals and keyword competitiveness.
- Use automated bidding strategies (CPC, CPA, ROAS) depending on your campaign goals.
2. Regularly Analysing Campaign Results:
- Monitor key performance indicators (CTR, conversions, cost per conversion).
- Use analytics tools to assess the impact of different campaign elements.
3. Combining the Two Processes:
- Adjust bids based on your results analysis, raising bids for the elements that perform best.
- Respond quickly to market changes and user behaviour by experimenting with different bids.
Effective Google Ads campaign management requires a balance between adjusting bids and regularly analysing results. This lets you optimise campaign performance while keeping control over your budget.
How Do You Optimise Google Ads Shopping Campaigns?
Optimising a Shopping campaign in Google Ads is key to increasing revenue and campaign performance. Here are a few tips on how to do it, taking into account ROAS (return on ad spend) and product margins:
- Focus on ROAS: ROAS is the primary metric for assessing Shopping campaign performance. Optimise your ads to achieve the highest possible return on investment. Pay attention to the products and product groups generating the best results, and allocate a bigger budget to the most profitable ones.
- Analyse your product margins: Besides ROAS, it's important to factor in the profit margin on each product. Focus your advertising efforts on higher-margin products, since selling these will bring a bigger net profit even if their ROAS is similar to that of lower-margin products.
- Optimise your ad content: Make sure your Shopping ads are appealing and include the key information that can catch potential customers' attention. Good product photos, clear descriptions and attractive pricing can significantly boost ad performance.
- Adjust bids and budgets: Regularly adjust your bids and campaign budgets based on results. Products with a higher ROAS and margin may need higher bids to maximise their visibility.
- Segmentation and targeting: Use advanced targeting to reach the most relevant audience. Segment your campaigns by demographics, interests and purchase history to increase ad performance.
- Test and analyse: Regularly test different aspects of your Shopping ads, including photos, descriptions and keywords. Analyse the results to understand which elements convert best and make adjustments accordingly.
- Use Smart campaigns: Consider using Google's Smart campaign features, which automatically adjust ads to increase conversions based on machine learning algorithms.

Excluding Poor Placements in Google Ads Display and Video Campaigns
One common mistake in managing Google Ads campaigns is failing to check where your ads are actually shown. By default, Google can display ads in places that aren't optimal, including mobile apps, which often leads to wasted budget. Here's how to effectively exclude poor placements:
- Analyse and identify poor placements: Regularly review where your ads are being shown. Use the data available in Google Ads to identify websites or apps generating a low conversion rate or that don't match your targeting.
- Exclude underperforming placements: Once you've identified placements that aren't delivering the results you expect, exclude them. In your ad group settings, you can use the option to exclude specific sites, content categories or apps.
- Monitor placement performance: Regularly check how your placements are performing. Excluding poor placements should be an ongoing process, to make sure your ads are shown where they have the best chance of success.
- Focus on Search and relevant sites: Rather than relying on Google's default placements, focus on the Search Network and selected sites that better match the profile of your potential customers.
- Optimise ads for chosen placements: Adjust the copy and call to action in your ads to make them more effective for your chosen placements. This will help increase campaign performance and ROI.
- Protect personal data: Make sure that excluding placements doesn't breach any privacy or personal data protection rules.
To sum up, excluding poor placements is key to optimising Google Ads campaigns. This process helps you avoid wasting budget on underperforming placements and focus on the ones that deliver the best results, increasing the overall performance of the campaign.
Creating and Evaluating Seasonal Campaigns, Budget Management and Planning Future Activity in Google Ads

Creating and evaluating campaigns for special occasions such as Black Friday, managing your budget and planning future Google Ads activity all require a strategic approach and ongoing optimisation. Here's how you can bring these aspects together to maximise campaign performance.
1. Creating Campaigns for Special Occasions:
- Plan ahead and segment: Plan your campaigns in advance, segmenting your target groups and adapting your messaging, for example by sending a newsletter announcing upcoming promotions.
- Use the right search terms: Focus on search terms related to the special occasion. For Black Friday, for example, use phrases such as “Black Friday deals” or “Black Friday sale”.
- Adjust your budget: Increase the budget for these campaigns to make the most of the higher traffic and interest during promotional periods.
2. Managing Your Budget and Spend:
- Monitor and adjust: Regularly monitor spend and check campaign performance. Use tools such as the search terms report to understand which phrases are delivering the best results.
- Negative keywords: Add negative keywords to avoid wasting budget on irrelevant queries.
- Optimise your campaigns: Continuously optimise your campaigns, adjusting bids and shifting budget towards your best-performing ads.
3. Planning Future Activity:
- Analyse and report: Once a campaign has ended, analyse its results using the performance report to understand what worked and what needs improving.
- Long-term strategy: Use this data to plan future activity, building on what worked and dropping what was less effective.
- Use data for optimisation: The data gathered during a campaign can be used for further Google Ads campaign optimisation, both in terms of keywords and audience segmentation.
