After working with dozens of websites over the years, Matter Solutions has noticed a pattern: technical SEO debt doesn’t announce itself. It just sits there, silently dragging rankings down until someone finally runs an audit and finds the damage.
We know this topic can sound dry at first, maybe even a bit technical. But once you read through what happened during one of our audits, you’ll see why fixing debt isn’t about finding every issue.
Before moving further, we need to set the stage. So, we’ll start with what technical SEO debt actually means, then walk through what the audit uncovered. Let’s dig into it.
What Is Technical SEO Debt, and Why Does It Build Up?
Technical SEO debt is the pile of small, unresolved issues that build up over years. Search engines don’t punish this instantly. Rankings slip slowly, and most site owners miss it until the drop is obvious.
Here’s the thing: technical fixes rarely feel urgent. A slow page or a missing tag doesn’t break anything today, so it gets pushed down the list. And that’s exactly how debt accumulates in the first place.
Once ten or more of these issues stack on top of each other, though, the damage compounds. Each one chips away at a ranking factor search engines actually track. So, the website ends up fighting an uphill battle it never needed to face.
The Audit That Revealed a Decade of Problems
We expected to find a handful of issues during this site audit. Instead, we found a decade’s worth of neglect sitting right under the surface.
The website had grown over the years without anyone circling back to clean up old mistakes. So, the entire site carried technical issues stacking up in the background.
Here’s what we found once we started digging.
Duplicate Content Hiding in Plain Sight
Old URL structures and leftover parameters had created several versions of the same pages. When a visitor landed on one version through a social link and another through a search result, Google treated them as separate pages competing against each other. This split ranking signals across multiple URLs instead of letting one page earn full credit.
Along with the split signals, Google also had to choose which version to show in search results, and it didn’t always pick the strongest one.
However, fixing it meant consolidating the duplicates and redirecting them back to a single, stronger page. Once that redirect was live, rankings for the main page started climbing within weeks.
Page Speed and Loading Speed Issues Nobody Fixed
Bloated scripts and unoptimized images were dragging load times down across the site. After running the numbers, we found some pages took over six seconds to load on mobile, well past the point where visitors give up and leave.
Worth noting: Slow loading speed not only frustrates visitors. It also tells Google the page is a poor experience, which drags rankings down too.
Besides compressing images, we trimmed unused scripts and combined several style sheets into one file as well. What’s more, we set up lazy loading for images further down the page, so they only load once a visitor scrolls to them. Page speed dropped from six seconds to under two within a few weeks after doing these.
Core Web Vitals Scores That Never Improved
Core Web Vitals measure three specific things: how fast a page loads, how quickly it responds to clicks, and how much it visually shifts while loading. Nobody had tracked these scores in years, so they stayed poor by default. When a page shifts around while loading, like a button moving right as someone tries to click it, that counts directly against the score.
Once we fixed the layout shifts and sped up the load times from the previous section, two of the three scores moved into the “good” range within a month. The third, response time, took a bit longer since it meant rewriting some older scripts from scratch.
Can You Fix Everything at Once? The Prioritization Problem
No, you can’t fix everything at once, and trying to is where most technical SEO efforts fall apart. Prioritizing the fixes that move rankings gets you further than cataloguing every issue you find.
When our audit turned up dozens of problems, the instinct was to tackle all of them in order. But that approach burns weeks on low-impact fixes while the issues actually hurting rankings sit untouched. So, we ranked each problem by how much it likely affected search visibility, not by how easy it was to fix.
This makes sense once you think about it practically. A business with limited time and resources gets further by fixing three high-impact issues than by clearing twenty small ones. That’s the one lesson worth taking from this entire audit.
Small Fixes With Big Payoffs
Some of the smallest fixes on this site moved rankings faster than anything else we touched. None of them took more than a few hours to implement.
Once the bigger issues were handled, these smaller fixes were next on the list. They required far less effort than the duplicate content or page speed work from earlier, too.
Let’s break down the three wins that made the most impact.
1. Internal Links That Guide Search Engines
Internal links help search engines crawl and understand how pages on a site relate to each other. Without enough links pointing to a page, search engines can struggle to find it at all, and it ends up buried in the index with almost no visibility.
After mapping out the entire site structure, we found over forty pages with zero internal links pointing to them. We added links from relevant articles first, then placed a few of the most important pages directly in the main navigation. Those orphaned pages started appearing in search results within two weeks.
2. Schema Markup for Better Search Results
Schema markup is code added to a page that tells search engines exactly what the content means, like whether it’s a recipe, a review, or a product listing. Without it, Google has to guess at context, and guessing often means missing out on rich snippets in search results.
Once we added structured data to the product and review pages, click-through rates climbed noticeably within the first month. Google started showing star ratings and prices directly in search results, which made those listings stand out against competitors with plain blue links.
3. Alt Text and Overlooked Accessibility Wins
Alt text describes an image for people using screen readers, and it also gives search engines context about what that image shows. Hundreds of images across the site had none at all, which meant missing out on image search traffic entirely.
After writing descriptive alt text for every product image, traffic from image search picked up within a few weeks. Along with the ranking benefit, the site also became more usable for visitors relying on screen readers, so it solved two problems at once.
What Comes Next? Protecting Your Search Visibility
Now that the major issues are fixed, the real work shifts to keeping them fixed. Search visibility isn’t a one-time win. It needs regular attention going forward.
So, what should you keep an eye on after an audit like this? Here are the next steps worth building into a routine:
- Run quarterly technical audits on key pages
- Monitor page speed and loading speed regularly
- Scan for broken internal links every month
- Keep schema markup updated as pages change
- Check mobile usability across top search results
None of these steps take long on their own. But skip them for a year, and the same debt from earlier starts building right back up.
Ready to Stop Guessing and Start Prioritizing?
Fixing a decade of technical SEO debt taught us one thing above everything else. The goal was never finding every issue on the site. It was learning which ones actually moved the needle and fixing those first.
If your own website has years of small issues piling up, you’re probably feeling that same pull to fix everything at once. Resist it. Start with what’s hurting your rankings the most, then work your way down the list.
Matter Solutions has run this exact process for businesses across several industries. Reach out when you’re ready to find out what’s actually holding your site back.
