How to Fix the Technical SEO Issues That Actually Matter

Run almost any small business site through a technical SEO crawler and it will come back with a list that looks alarming: dozens, sometimes hundreds, of "issues." Most business owners either panic and try to fix everything, or shut the report and never look at it again. Neither is right. The overwhelming majority of what a crawler flags has little to no effect on whether you rank. A small number of issues genuinely matter, and this guide is about telling the two apart.

What "technical SEO" actually means

Technical SEO is the part of SEO that has nothing to do with what your pages say, and everything to do with whether search engines can reliably find, load, and understand them in the first place. Good writing on a page nobody can load doesn't help anyone. Think of it as the plumbing: invisible when it works, and the reason nothing else works when it doesn't.

The issues actually worth fixing first

Pages Google can't find or isn't indexing

This is the single highest-priority category, because a page that isn't indexed cannot rank for anything, no matter how good it is. Check Search Console's Page indexing report for statuses like "Discovered, currently not indexed" or "Crawled, currently not indexed" on pages you actually care about. A page that's been sitting in either state for weeks, with no obvious reason (it's not thin, it's not a genuine duplicate, it's linked to from elsewhere on your site), is worth investigating properly. For the full walkthrough of reading this report, see How to Find SEO Opportunities in Google Search Console.

Pages that don't load fast enough, or shift around while loading

Google measures real loading and visual-stability experience through a set of metrics it calls Core Web Vitals: how quickly the main content appears, how quickly the page responds to the first interaction, and how much visible content jumps around as it loads. Google's own documentation is direct that page experience is one of many signals used in ranking, and that it matters most as a tie-breaker between pages that are otherwise similarly relevant. A page with brilliant content that takes eight seconds to become usable, or one where a banner ad pushes the whole page down just as someone tries to tap a button, is giving up an advantage for free. This is rarely something you fix by rewriting copy: oversized images, too many third-party scripts (chat widgets, ad networks, tracking pixels stacked on top of each other), and unoptimised hosting are the usual causes.

Broken links and dead pages

A link, internal or external, pointing to a page that no longer exists wastes a visitor's click and wastes a search engine's crawl budget on nothing. Long chains of redirects (page A redirects to B, which redirects to C) slow things down and occasionally break entirely. Check your own site periodically the way a visitor would, and treat any 404 you find on a page you still care about as worth either restoring the content, redirecting it properly to its real replacement, or removing every link that still points to it.

Missing or duplicated title tags

Every page needs its own title, specific to that page, never copy-pasted sitewide. Two pages sharing an identical title confuses both a reader with two tabs open and a search engine trying to work out which page is the better match for a given search. This overlaps closely with click-through rate, which has a dedicated guide: How to Improve Google Search CTR With Better Titles and Descriptions.

Pages that don't work properly on a phone

Google has used mobile-first indexing for years now, meaning it primarily uses the mobile version of your page to understand and rank it, not the desktop version. Text too small to read without zooming, buttons too close together to tap accurately, or content that's hidden or broken on a phone screen, aren't a secondary concern behind desktop, they're the primary version Google is actually evaluating.

Missing or broken structured data on your key pages

Structured data (schema markup) labels the content on a page so machines don't have to guess what it means. It won't rescue a thin or poorly structured page, but on an already-solid page it's a genuinely useful, low-effort addition. How to Structure a Service Page for SEO, AEO and GEO covers which schema types are actually relevant for a small business page and what they do.

What's usually safe to leave alone

A long crawl report often pads its count with items that rarely move anything for a small site: minor console warnings with no visible effect, a missing meta keywords tag (deprecated and ignored by Google for well over a decade), slightly inconsistent heading hierarchy on a page that otherwise reads clearly, or a handful of external links flagged only because a checker couldn't confirm them quickly. None of these are worth an afternoon of anyone's time. If a report doesn't distinguish between "this is quietly costing you rankings" and "this is technically true but irrelevant," treat every item on it with proportionate scepticism rather than working straight down the list in order.

A useful filter: does this issue affect whether a real page, that real customers would want, can be found and loaded properly? If yes, it's worth fixing. If the honest answer is "it's just untidy," it can wait.

How to check all of this yourself

You don't need to hire anyone to find most of these issues. PageSpeed Insights gives you a free, direct read on Core Web Vitals for any page, including specific suggestions on what's slowing it down. Search Console's Page indexing and URL Inspection reports show you exactly what Google has and hasn't indexed, and often why. A general-purpose technical SEO crawler, including EightySixOS's own Technical Health check, can surface broken links, missing titles, and mobile issues automatically across a whole site, which is faster once you have more than a handful of pages, but the tools above cost nothing and cover the fundamentals on their own.

When you genuinely need a developer

Most content and structural fixes, rewriting a title, adding schema, fixing an internal link, are things a business owner can do directly in most website builders. What genuinely needs a developer is usually server-level: hosting that's fundamentally too slow, a site built on unmaintained or bloated code, or a Core Web Vitals problem rooted in how the site is built rather than in one oversized image. Before paying for developer time, confirm the specific problem with the free tools above, so you're paying to fix something diagnosed and real, not paying for a vague "site audit" that rediscovers the same list a free crawler would have given you.
