Why a Technical SEO Audit Must Last at Least 10 Business Days

Data Doesn't Come Out of Thin Air

Audit work in our office at Chorzowska 50 begins with setting up professional crawlers. We don't use tools that only check the home page. Our process involves scanning every URL in your service. For a medium-sized IT portal with about 8,430 subpages, gathering raw data on HTTP response codes alone takes us nearly 6 hours. We must be sure that no 404 error or incorrect 301 redirect escapes our notice.

Then comes the time to analyze server logs from the last 90 days. This allows us to see how Google's robot actually behaves on your site. Many companies think their site is working well until we show them that Google wastes 42% of its time indexing irrelevant tags instead of offers. Such an analysis requires calm and precision that cannot be achieved in a single afternoon. Data speaks for itself, and we do not accept haste here.

We check facts, we don't promise miracles. Real server log analysis is the only way to know the truth about your site.

147 Checkpoints on Our List

Every audit conducted by Silesia Performance Lab goes through a rigorous checklist. We check exactly 147 technical elements. This includes errors in Schema structured data, JavaScript rendering issues, and content duplication. In October 2024, we detected that for one of our SaaS clients, incorrect canonical tags were blocking the indexing of 34% of key offer pages. If we were doing a one-day audit, this detail would have been missed by automatic scanners.

We spend an average of 22 minutes manually verifying each of the most difficult points on our list. We do not send reports generated with one button. Marek Wiśniewski personally checks how your site handles script interpretation that might slow down content loading. It often turns out that a seemingly small code error generates losses of several thousand zlotys per month due to lost leads. A specific audit means specific profits in the future.

Speed Tests on Real Devices

We don't rely solely on theoretical results from online testers. At Silesia Performance Lab, we check load times on physical devices we have in Katowice. We use phones with different processing power because we know that 19% of your users might be using older smartphone models. We measure LCP and CLS layout shifts at various internet speeds. This shows us the real picture of what a potential client looking for IT services sees.

The average page rendering time for the technology sector we audited in the third quarter of 2024 was 4.3 seconds. Our goal is to get below 1.7 seconds. Every second of delay increases the risk that the user will click 'back' and go to the competition. We do technical SEO that works, so we examine every millisecond of delay resulting from overloaded graphics or overly heavy tracking scripts.

The Result is Not a PDF, But a Specific Task List

The report you receive after 10 business days usually counts from 47 to 63 pages of pure facts. You won't find generalities there. Instead, you'll get a table with implementation priorities. For example, in an audit for a programming company from Gliwice in May 2024, we pointed out 14 critical errors in the robots.txt file. The programmers fixed them in 3 hours, and the result was a 28% increase in the number of indexed pages in just 12 days.

Every recommendation in our report is described so that your IT department knows exactly what to do. We don't use complicated jargon where it's not needed. We focus on what will bring the fastest return on investment. We've been doing this since September 2016 and know that only this approach builds trust. After the audit is completed, we offer a 45-minute consultation to explain every point and answer your technicians' questions.

Our report is a ready battle plan for your programmers. Zero fluff, just technical instructions.
