Businesses are increasingly turning to Pay-Per-Click (PPC) advertising to drive traffic, increase sales, and gain visibility. However, one of the factors that can significantly impact PPC performance, often in ways marketers don’t anticipate, is algorithm updates. These updates, particularly from search engines like Google, can have far-reaching effects on how PPC campaigns perform. In this blog post, we’ll explore how algorithm changes can affect your PPC marketing campaign and provide practical tips on how to adapt to these updates.

What Are Algorithm Updates?

Before diving into the impact on PPC, it’s crucial to understand what algorithm updates are. Algorithm updates are changes made by search engines (like Google, Bing, or Yahoo) to their ranking algorithms. These updates are designed to improve the search engine’s ability to deliver relevant results, improve user experience, and filter out low-quality content.

For example, Google frequently rolls out updates such as the “Core Web Vitals” or “BERT,” which affect the way they rank both organic and paid search results. While these updates are often associated with SEO, they can also directly impact PPC campaigns, especially as Google integrates machine learning and AI into its advertising products.

How Algorithm Updates Can Impact Your PPC Campaign

1. Changes to Ad Ranking and Quality Score

Google’s algorithm updates can directly affect how your ads are ranked. Google Ads uses a system called Quality Score, which evaluates the relevance and quality of your ads, keywords, and landing pages. Google’s algorithm updates might change the factors that influence Quality Score, or introduce new signals such as load speed or user experience on landing pages. As a result, your campaign’s performance could take a hit if these new signals aren’t aligned with your existing setup.

For instance, if Google updates its algorithm to place more importance on mobile user experiences, advertisers with poorly optimised mobile landing pages could see their ads rank lower. In contrast, advertisers that optimise for mobile might gain an advantage in the bidding process.

2. Impact on Keyword Relevance

With frequent algorithm updates, search engines continuously improve how they interpret search intent. These updates may cause search engines to interpret your keywords differently. For example, if you’re running a campaign targeting a broad keyword, but an update changes how that keyword’s relevance is evaluated, your ad could become less effective.

To mitigate this, you should regularly monitor keyword performance and look for patterns that indicate a shift in user behaviour or keyword effectiveness. It’s essential to use negative keywords and refine your match types to ensure that your ads continue to target the most relevant search queries.

3. Changes in Ad Competition

Google’s algorithm updates don’t just impact your PPC campaigns directly, they also affect your competition. If competitors change their strategies to take advantage of new updates or improve their Quality Scores based on new ranking factors, your costs per click (CPC) may increase, or you could face more competition for high-value keywords.

It’s crucial to monitor your competitors’ actions and remain prepared to swiftly adjust to shifts in the competition, whether it’s by adjusting bids, enhancing ad relevance, or concentrating on less competitive long-tail keywords.

4. Mobile-First and User Experience Signals

As part of its core updates, Google has increasingly placed more emphasis on mobile-first indexing and user experience signals, particularly the Core Web Vitals. These updates prioritise fast-loading, mobile-friendly websites that provide seamless browsing experiences.

For PPC marketers, this means that optimising your landing pages for mobile users and improving page load speeds are no longer optional, they are essential for maintaining a good quality score. Ads leading to slow-loading or non-mobile-friendly pages could see a drop in rankings and increased costs due to lower Quality Scores.

5. Machine Learning and Automation Features

Google has been integrating machine learning and automation into its advertising systems, and algorithm updates often refine these AI-driven tools. For instance, Smart Bidding and automated ad targeting features like Dynamic Search Ads (DSA) rely heavily on machine learning algorithms to optimise campaigns.

While automation can save time, it can also make your campaign more vulnerable to changes in the algorithm, as the automated system may adjust your targeting or bids in ways you don’t expect. Regularly monitor and adjust these automated features to ensure they align with your goals, especially after a major algorithm update.

How to Adapt Your PPC Strategy to Algorithm Updates

1. Stay Informed About Algorithm Changes

One of the best ways to minimise the impact of algorithm updates on your PPC campaigns is to stay informed. Search engines, particularly Google, frequently release announcements regarding updates. Subscribing to Google’s official blog, following industry news, and joining PPC-related forums and groups can help you keep up with the latest developments.

If you understand what the update aims to achieve, you can adjust your campaigns proactively instead of reacting after a decline in performance.

1. Regularly Audit Your Campaigns

When a major algorithm update occurs, take time to audit your PPC campaigns. Review keyword performance, Quality Scores, and click-through rates (CTR). Identify any trends that suggest your ads are no longer as relevant or effective as they once were. A comprehensive audit helps pinpoint areas where adjustments are necessary.

2. Improve User Experience on Landing Pages

As SEO and PPC increasingly consider user experience, it’s crucial to consistently enhance the user experience on your landing pages. Ensure they load quickly, provide high-quality content, and are easy to navigate. Test different elements (like buttons, images, or calls to action) using A/B testing to find what works best for your audience.

3. Monitor Competitor Activity

Algorithm updates can shift the competitive landscape. By monitoring your competitors’ strategies and adapting to any new trends, you can ensure your PPC campaigns remain competitive. Use tools like SEMrush, SpyFu, or Google Ads Auction Insights to gain a better understanding of what your competitors are doing and adjust your bidding strategies accordingly.

4. Leverage Automation with Caution

While automation tools like Smart Bidding can be powerful, they are not foolproof. Always monitor automated strategies and make manual adjustments when necessary. If an algorithm update changes the way automated features work, ensure you understand the impact on your campaigns and adjust accordingly. It might be a good idea to test a few campaigns with and without automation to understand what works best.

Conclusion

Algorithm updates are inevitable in the digital world, and they can significantly affect your PPC marketing campaigns. Whether it’s changes to how Google ranks ads, shifts in keyword relevance, or increased competition, staying ahead of algorithm changes is key to maintaining a successful PPC strategy. By staying informed, auditing your campaigns regularly, improving landing page experiences, and adapting automation tools, you can ensure your PPC campaigns remain effective and cost-efficient, no matter what updates come your way.

If you’re serious about maximising your PPC performance, make algorithmic monitoring and strategic flexibility a core part of your approach. This will allow you to thrive in an ever-changing digital advertising environment.
