Sometimes, the biggest improvements come down to which issues you address first — and when. That was the key takeaway from a recent technical SEO audit my team conducted for a prominent global B2B technology company. Following the company’s website migration, we were tasked with establishing a performance baseline, identifying opportunities to improve SEO and GEO performance, and helping implement recommendations within a limited timeframe. Here’s what we found. ## What the post-migration SEO audit revealed Using Screaming Frog SEO Spider, we conducted sitewide crawls to identify technical issues affecting the client’s organic search performance after the migration. We also incorporated GA4 traffic data and Google Search Console data on indexing, crawling, clicks, and impressions to help prioritize the findings. The audit uncovered several issues commonly found after a website migration: - About 100 priority orphaned URLs with traffic. - 175 priority pages with missing meta descriptions and overly long page titles. - Incorrect menu link mappings. - Tens of thousands of 301 redirect chains and loops. - About 500 URLs containing underscores. - More than 4,400 pages with 404 errors. - Pages missing hreflang tags. - More than 7,800 parameterized URLs being crawled and indexed. - More than 250 pages with canonical tag issues. - Missing x-default. ## Here’s what mattered Fixing the site’s technical SEO issues improved crawling and indexing, but rankings, traffic, and visibility didn’t immediately follow. Those gains began to appear only after we implemented metadata updates. ![Image 44](https://searchengineland.com/wp-content/seloads/2026/10/image-44.png) Of the issues identified in the audit, we prioritized redirects, hreflang, 404 errors, metadata, canonicals, and orphaned URLs. With limited hours and resources, we had to be strategic about which issues to address and where. Creating metadata for thousands of pages wasn’t feasible, so we used first-party GA4 data to identify priority pages where both the page title and meta description could be optimized. We first fixed 404 errors, 301 redirect issues, and canonical link errors. We also provided guidance on menu mapping for orphaned URLs and assisted with redirect mapping. Indexing errors declined, and crawl rates improved. However, rankings, traffic, and visibility didn’t immediately improve. The turning point came after we implemented metadata updates in early August. Organic visibility began to improve, even though metadata was the lowest-effort part of the work. No single fix was responsible for the gains. The foundational technical work made the pages more accessible to search and AI crawlers, while subsequent metadata optimizations helped improve their visibility. Metadata was also the only element we directly controlled from identification through recommendation and implementation. ## The results: Organic traffic, impressions, and AI referrals increase Following the technical SEO audit in the spring and implementation work from June through August, the client’s organic search performance improved significantly. A comparison of September and August performance, using first-party GA4 and Google Search Console data alongside Semrush domain ranking data, showed the following gains: - 121% month-over-month increase in organic traffic ![Image 45](https://searchengineland.com/wp-content/seloads/2026/10/image-45.png) - 13% increase in Google AI Overviews citing the client. ![Image 47](https://searchengineland.com/wp-content/seloads/2026/10/image-47.png) - 275% increase in AI assistant referral traffic. ![Image 46](https://searchengineland.com/wp-content/seloads/2026/10/image-46.png) Improved indexability and clarity also contributed to the client’s organic visibility, with a 229% month-over-month increase in Google Search Console impressions. ## Why the order of fixes matters Knowing when to fix technical SEO issues — and when to leave them alone — is key to managing technical debt. Technical SEO audits often produce extensive lists of issues. But prioritization goes beyond ranking them by impact or addressing every high-priority item. Sometimes, you don’t even need to fix every affected page within a high-priority category. You need to be surgical and deliberate about sequencing. For example, if every page on a site is missing titles and meta descriptions but also has indexing problems, fixing those problems should come first. Even the best content and most optimized metadata won’t matter if Google can’t discover, crawl, render, and index the pages. Think of it like building a deck. You could design the best-looking deck, but if you cut corners on materials or labor, it might collapse or need rebuilding within a year. The foundation matters as much as the finished product. The same applies to SEO. It’s an always-on channel that requires consistent, quality improvements over time. Chasing a single magic bullet won’t deliver lasting results. In this case, optimizing page titles and meta descriptions for priority pages improved organic and AI search performance. But without the foundational work to improve crawlability, discoverability, and indexing, we wouldn’t have achieved those results. You don’t need to fix everything everywhere. The next time you conduct an audit, even if you don’t have a defined scope, approach it as though your resources are limited. Ask yourself: What would you fix, and where?
