How Regular SEO Audits Can Help You Stay Ahead Of Google Algorithm Updates?
On the 10th of November 2026 Google released its third core update of the year. Thousands of website owners checked their analytics dashboards the next day. Some saw their rankings increase while others saw a decrease in traffic without knowing why.
This is usually not down to luck. Websites that have regular SEO audits will typically be in a better state and will be much easier to troubleshoot. This guide will explain how Google updates work, how a regular audit will help you avoid being affected by them and when to use a professional SEO audit service.
Why Some Websites Are Hit Harder By Google Updates?
Google regularly updates its search systems. However, there are only a few types of updates that are important to businesses.
- Core updates – This helps Google make broad changes to how content is seen as high quality and relevant.
- Spam updates – This penalises websites using spammy tactics.
- Feature updates – Such as the Discover core update in February 2026.
2026 Has been a busy year for Google. They have released three core updates (March 27th to April 8th, May 21st to June 2nd, and November). There have also been several spam updates and one Discover-only update. Each update will take between 1–3 weeks to roll out meaning your rankings may not be stable for a while. Google always says that its core updates are not targeted to specific websites and there is no one trick to recover from them. They are rewarding genuinely helpful, accurate and trustworthy pages. If your website has not been regularly maintained and has built up several technical issues, outdated pages and thin content, then you will be more vulnerable.
What Is An SEO Audit?
An SEO audit is a thorough check of your website. It will include checking crawlability, indexation, speed, mobile friendliness, on-page elements, content quality, backlinks and tracking. If done regularly this will help you identify issues early. There are three main reasons why they help:
- Identify issues early – Crawl errors, indexation errors and slow templates will be addressed before they become a bigger issue.
- Provide a benchmark – You will know what your website usually looks like, so if something changes after an update you will be able to identify it.
- Help with prioritisation – You will know what to focus on fixing.
7 Reasons Why Regular Audits Help You Stay Ahead
1. Identify technical issues early
Websites are constantly changing. Adding new plugins, redesigning or editing templates can cause noindex tags to be added, important folders blocked in robots.txt or canonical issues. An audit will help you identify these issues early.
2. Ensure content is helpful
Core updates reward content that answers searches and provides genuine experience and expertise. A regular content audit will help you identify outdated stats, thin/duplicate pages and topics that your competitors are now answering better than you. Updating or merging these pages will help your website stay up to date.
3. Reduce spam issues
Spam updates will penalise websites using spammy tactics. An audit will help you identify any issues with your backlinks, auto-generated or low quality pages and anything that could be misunderstood by a spam system. If your previous agency/contractor didn’t follow best practice this could be an issue.
4. Provide a benchmark
If your traffic has changed during an update the first thing to check is if it is due to the update. Having audit data will allow you to compare groups of pages, templates and keywords before and after. This will help you identify if it was the update or if it was due to seasonal issues, tracking errors or changes on your website.
5. Improve user experience
A fast, mobile-friendly and stable website will help improve your rankings and conversions. Regularly checking your Core Web Vitals (LCP, INP and CLS) will help you avoid pages slowing down.
6. Prepare for AI-powered search
More and more search results are using AI. Having an audit will help you ensure that your best pages are crawlable, clear, have accurate schema and are written to answer questions. This will help improve your traditional rankings and help you be seen in AI answers.
7. Identify opportunities that competitors have missed
There will always be winners and losers from an update. Using an audit with competitor and keyword gap analysis will help you identify where your competitors have dropped, where you can improve and what pages need more internal links or updating.
How Often Should I Do An Audit?
While there isn’t a set schedule, most businesses will benefit from doing the following:
Monthly – Quick check of Search Console, crawl errors and key rankings.
Quarterly – Thorough check of technical issues, content and backlinks.
Yearly – Full audit of everything. This will give you a fresh roadmap.
After a big change – Redesign/migration, platform changes or a big drop in traffic.
Large e-commerce, publishing and multilingual websites will change more frequently and will generally benefit from more regular audits.
What Should I Do During An Update?
It is best to stay calm. When Google announces an update:
- Check the Google Search Status Dashboard to see when it started and how big it is.
- Avoid making any major changes. Your rankings will be unstable while it rolls out and any rushed changes will make it harder to troubleshoot.
- After the update has finished running, compare your performance to your benchmark.
- Break down your data by page type, topic and device to identify where the changes have occurred.
- Audit the pages to ensure they are high quality, have the right intent, no technical issues, and that your competitors have improved.
Make continual improvements. Google has said it can take some time to recover from an update and you may not see any improvements until later updates. Focus on improving the quality of your website.
In-House Or Professional?
You can do monthly checks and basic quarterly audits in-house using Search Console, analytics and a crawler. However, if you have a large or complex website, traffic has dropped and you are unsure why, planning a migration or you don’t have technical SEO knowledge then a professional SEO audit service will be beneficial.
A good provider will provide a prioritised action plan. They should be able to explain the issues clearly, provide evidence to support their recommendations, realistic timescales and help with implementation. Be wary of anyone guaranteeing rankings.
FAQ

No, nobody can control Google. However, having regular audits will help reduce your vulnerability by ensuring your website is in good technical shape, has good quality content and backlinks.
2. How do I know if my website was affected by an algorithm update?
Compare your Search Console data before and after. Ensure the timing matches up with Google and there are no tracking issues or changes on your website.

Google usually says up to 2 weeks. The core updates in March and May 2026 lasted around 12 days.
4. Should I make any changes to my website during an update?
Avoid making any major changes. Any obvious technical issues can be fixed but avoid changing any content.
5. How much do SEO audit services cost?
This will vary depending on the size of your website and how in-depth you want it to be. Ensure you have a clear idea of what they will do.
6. Should I just do one audit?

Conclusion
Google will continue to update its search systems. No business will be able to predict every change but by having regular audits you can ensure your website is in a good place. You will have a solid technical foundation, helpful content and low risk. You will also have data to help troubleshoot.
Start by providing a benchmark and doing simple regular audits. If your website is complex then use a specialist SEO audit service. By being organised with your updates you will turn uncertainty into an advantage.
