5 Technical SEO Problems That Kill 90% of Websites

Learn the 5 biggest technical SEO problems affecting your site and practical ways to fix them for higher visibility and faster growth.

5 Technical SEO Problems That Kill 90% of Websites

The day my website completely disappeared from Google, I had no idea what “crawl budget” meant, you know, the scary March core update.

I was running a successful blog with 50,000 monthly visitors when suddenly- poof- my traffic dropped to almost zero overnight. My rankings vanished. My carefully crafted content became invisible.

I frantically called my developer friend at 11 PM, practically in tears. “Something’s wrong with my website! Google can’t find it anymore!”

Jake logged into my site and, within five minutes, said the words that still haunt me- “Your robots.txt file is blocking Google from crawling your entire website.”

I had no clue what that meant. All I knew was that one tiny technical mistake had destroyed months of hard work.

That’s when I realized the harsh truth- you can write the best content in the world, but if your technical SEO is broken, nobody will ever find it.

Here’s the thing- technical SEO sounds scary, but it doesn’t have to be. You don’t need to become a developer. You need to understand the basics and know what to look for.

This guide will show you exactly how to audit and fix your website’s technical SEO, even if you can barely tell the difference between HTML and HTTP.

What Technical SEO Actually Controls?

  • Whether Google can find your pages at all
  • How fast your website loads (Google’s #2 ranking factor)
  • Whether your site works on mobile devices
  • If search engines can understand your content structure
  • How easily Google can crawl through your entire website

The Business Impact- When technical SEO is broken, you lose more than rankings. You lose-

  • Organic traffic (obviously)
  • Potential customers who can’t find you
  • Revenue from search-driven sales
  • Credibility with your audience
  • Time and money spent creating content nobody sees

Questions to ask-

The Visual Technical SEO Troubleshooting Guide

Let me show you how to identify and fix the most common problems-

Visual Problems- The Crawling Catastrophe

What You’ll See-

  • Google Search Console Error-
  • Crawled- not yet indexed.
  • Found Discovered – not indexed at present.

What This Means in Simple English: Google has discovered your page, but has chosen not to include it in search results. It is a bit like you are invited to a party, but you are asked to wait outside.

How to Fix It-

  • See whether you have blocked the page with robots.txt.
  • In your page source, you should find some noindex tags.
  • Make sure that the page contains distinctive, useful content.
  • Add in-text links to the page.

Visual Clue- In Google Search Engine, you will observe a graph where the valid pages are falling and the excluded pages are increasing.

Visual Problem- The Speed Disaster

What You’ll Find in PageSpeed Insights-

  • Red performance score (0–49)
  • Caution regarding largest contentful paint.
  • “First Input Delay” issues
  • The diagnostics have giant file sizes.

What This Means- Your website loads slower than a dial-up modem in 1995. Before your page is loaded, users are gouting.

  • Hasty Solutions (No Code Writing)
  • Image compression: TinyPNG works to reduce the size of image files.
  • Switch to Better Hosting: Moving on to managed WordPress hosting.
  • Deactivate Unused Plugins: Deactivate plugins that you are not using.
  • Cache Enabling: Add a caching plug-in such as W3 Total Cache or Wp Rocket.

Visual Progress Indicator- You should see your PageSpeed score go red (0 to 49), orange (50 to 89), and green (90 to 100).

Visual Problem- The Mobile Mayhem

What You’ll See-

  • Small text that needs to be zoomed in to be read.
  • Buttons that are smaller than they can be tapped with fingers.
  • Horizontal scrolling needed.
  • Screen edges have cut-off content.

What This Would appear like in a Google test- Red error message: Text is too small to read, or Clickable objects are too near each other.

How to Fix-

  • Change to Responsive Theme: This is the theme that automatically adjusts to match the screen size.
  • Menu Navigation: Make sure your mobile menu functions properly.
  • Check Font Sizes: Ensure that text is at least 16px on mobile.
  • Test Forms: Check contact forms on phones.

Visual Problem #4: The URL Structure Mess

Bad URL Examples-

yoursite.com/p=123?category=blog&date=2024
yoursite.com/uncategorized/hello-world-2
yoursite.com/blog/blog/how-to-do-something

Good URL Examples-

yoursite.com/how-to-start-a-blog
yoursite.com/seo-tips-beginners
yoursite.com/content-marketing-guide

Visual Fix Checklist

  • URLs include target keywords
  • No random numbers or parameters
  • Hyphens separate words (not underscores)
  • Keep URLs under 60 characters when possible

Red Flags That Require Professional Help in Technical SEO

While most technical SEO can be handled with plugins and basic fixes, some issues need a developer-

Call a Developer If You See-

  • Server Errors (500, 503): Your hosting has serious problems
  • Hacked Content: Spam pages or content you didn’t create
  • Core Web Vitals Failures: Complex loading and interactivity issues
  • Security Issues: SSL certificate problems or malware warnings
  • Database Errors: Pages are returning error messages instead of content

Questions to Ask Your Developer-

  1. “Can you check our robots.txt file and sitemap?”
  2. “Are there any server-side speed optimizations we can implement?”
  3. “Is our SSL certificate properly configured?”
  4. “Can you audit our site for security vulnerabilities?”

The Success Metrics That Actually Matter

Forget vanity metrics. Here’s what to track-

Google Search Console Metrics

  • Total Clicks: Actual visitors from search
  • Average Position: Where you rank for important keywords
  • Coverage Issues: How many pages Google can’t access
  • Core Web Vitals: Loading speed and user experience scores

Website Analytics

  • Organic Traffic Growth: Month-over-month increases
  • Bounce Rate Improvement: People staying on your site longer
  • Page Load Speed: Consistent improvement in loading times
  • Mobile Traffic: A Growing percentage of mobile visitors

Business Impact

  • Lead Generation: More contact form submissions
  • Sales Conversion: A Higher percentage of visitors becoming customers
  • Brand Awareness: Increased branded search traffic

Conclusion

After helping hundreds of people fix their technical SEO, here’s what I’ve learned, Perfectionism is the enemy of progress.

You don’t need a perfect website. You need a functional website that Google can crawl, index, and understand.

Start with the basics-

  • Make sure Google can find your pages
  • Ensure your site loads quickly
  • Verify it works on mobile devices
  • Create clear, logical navigation

Once those fundamentals are solid, you can optimize the advanced stuff.

Remember, technical SEO isn’t about impressing developers with your code. It’s about removing barriers between your valuable content and the people who need it.

Your expertise deserves to be found. Technical SEO is just the bridge that connects your knowledge with your audience.
