Most websites have SEO problems. The difficult part is that you do not always know they exist until your traffic drops. SEO problems can quietly kill your rankings for months before you notice. A slow page here, a broken link there, and before long, Google stops sending visitors your way.
This guide covers the 10 most common SEO problems, what causes them, and how to fix each one.
Why SEO Problems Hurt More Than You Think
One technical issue can cost you 30 to 50 percent of your organic traffic.
That is not an exaggeration. A page that loads too slowly gets abandoned. A page blocked from Google gets zero impressions. A page with duplicate content splits its ranking power and ends up performing poorly.
Most businesses do not lose rankings because of a single big mistake. They lose rankings because of five or six minor issues that sit quietly on their site.
The longer these issues stay unfixed, the harder it becomes to recover. Google takes time to recrawl and reindex pages after changes. That means every week you delay fixing a problem is another week of lost traffic and missed leads.
The good news is that most SEO issues are fixable. You just need to know where to look.
1. Slow Page Speed and Failing Core Web Vitals
Page speed is one of the biggest ranking factors right now.
Google uses Core Web Vitals to measure how fast and stable your pages feel to users. The three main signals are:
LCP (Largest Contentful Paint): How fast your main content loads. Target is under 2.5 seconds.
INP (Interaction to Next Paint): How quickly the page responds to user input. Target is under 200 milliseconds.
CLS (Cumulative Layout Shift): How much the page shifts around while loading. Target is under 0.1.
If your pages fail these, Google sees your site as a poor user experience.
How to check it: Open Google Search Console and go to Core Web Vitals. You can also paste your URL into PageSpeed Insights for a full breakdown.
How to fix it: Compress your images. Use a fast hosting provider. Remove unused JavaScript and CSS. Use a content delivery network (CDN). Fix layout shifts by setting image dimensions.
2. Pages Indexed That Should Not Be (and Pages That Should Be, But Are Not)
Google indexing the wrong pages is a serious problem.
If your thank-you pages, admin pages, or duplicate URL variants get indexed, they compete with your real pages and waste Google’s crawl budget.
On the flip side, if your key service pages or blog posts are NOT indexed, they get zero traffic. Period.
How to check it: Open Google Search Console and go to the Coverage report. Look for pages with errors, excluded pages, and pages marked as “Discovered but not indexed.”
How to fix it:
Add a noindex tag to pages you do not want in Google’s index. Check your robots.txt file to make sure it is not accidentally blocking important pages. Make sure your key pages are linked internally so Google can find and crawl them.
3. Duplicate Content and Missing Canonical Tags
Duplicate content is common on e-commerce sites and CMS platforms like WordPress.
When two pages have very similar or identical content, Google does not know which one to rank. So it either picks the wrong one or ignores both.
This happens often with:
Product pages that appear under multiple URL paths. Pages with and without www or trailing slashes. Filter and sort pages on e-commerce sites that generate new URLs.
How to check it: Use Screaming Frog to crawl your site and look for duplicate page titles, meta descriptions, and content.
How to fix it: Add a canonical tag to the preferred version of each page. For e-commerce filters, either noindex the filter pages or block them in robots.txt.
4. Thin or Low-Value Content
Google wants pages that actually help users.
Pages under 500 words with no real depth, AI-generated text that says nothing specific, or pages built just to target a keyword without offering useful information all fall into this category.
Google refers to these as low-quality pages, and they can drag down the overall quality score of your entire site.
One thing many site owners miss is that thin content does not just hurt individual pages. It can trigger a sitewide quality issue. Google evaluates the overall quality of a domain, not just individual pages. If too many low-value pages exist, your stronger pages can also rank lower because of them.
How to audit it: Go through your pages sorted by word count. Flag any page under 400 words. Then ask: Does this page answer a real question? Does it give the user something useful?
How to fix it: Update thin pages with real, specific information. Add examples, steps, data, or answers to common questions. If a page has no clear purpose, remove it and redirect it to a stronger page.
5. Broken Internal Links and Redirect Chains
Every internal link on your site passes ranking power from one page to another.
Broken links pass nothing. Redirect chains, where a link goes through two or three redirects before reaching the final page, bleed that power at every step.
This is a common issue after site redesigns or when pages get deleted without proper redirects.
How to find them: Screaming Frog can crawl your site and show you every broken link and redirect chain.
How to fix it: Update broken internal links to point directly to the correct live page. Replace any redirect chains with a direct 301 redirect to the final destination. If a page no longer exists and has no good replacement, remove the links pointing to it.
6. Missing or Poorly Written Title Tags and Meta Descriptions
Your title tag is one of the first things Google reads to understand what your page is about.
A missing title tag means Google will write one for you, and it will not always be good. A title tag that is too long gets cut off in search results. A weak meta description means fewer people click your result, even if you rank.
How to check it: Use Screaming Frog or a free tool like Ahrefs Webmaster Tools to scan for missing, duplicate, or oversized title tags.
How to fix it:
Keep title tags between 50 and 60 characters. Put the main keyword near the front. Write meta descriptions between 130 and 155 characters. Focus on giving the user a clear reason to click.
Every page on your site should have a unique title tag and meta description. Duplicate title tags across multiple pages tell Google those pages are the same, which can cause ranking confusion. Review all pages, not just your top ones.
7. Keyword Cannibalization: Two Pages Targeting the Same Keyword
When two pages on your site target the same keyword, they compete against each other.
Google picks one to rank, and it often picks the wrong one. The result is that both pages rank lower than either one would if they were the only option.
This is a common SEO troubleshooting issue on blogs that have covered similar topics multiple times over the years.
How to check it: In Google Search Console, search for your keyword and see which URLs appear in impressions. If two URLs show up for the same term, you have a cannibalization problem. You can also use Ahrefs to check which pages rank for overlapping keywords.
How to fix it: Decide which page should rank for that keyword. Then either merge the two pages into one stronger page or update the weaker page to target a different keyword. Add a canonical tag from the weaker page to the stronger one if you cannot merge them.
8. Lack of Internal Linking
Internal links help Google understand which pages on your site matter most.
Orphan pages, pages with no internal links pointing to them, are nearly invisible to Google. Even if the content is strong, Google may not crawl or rank it without a clear link path from the rest of your site.
This is one of the most overlooked common SEO mistakes.
How to find orphan pages: Screaming Frog has a built-in orphan page report. You can also compare your sitemap against your crawl data.
How to fix it: Build a hub-and-spoke internal linking model. Your main service or topic pages are the hubs. Blog posts and supporting pages are the spokes. Every new piece of content should link to its hub, and hubs should link out to key supporting pages. Aim for at least two to three relevant internal links per page.
For a deeper look at how this works in practice, read Moz’s guide to internal linking, which breaks down how link equity flows through a site.
9. Missing or Broken Schema Markup
Schema markup tells Google exactly what your content is about, so it can display rich results in search.
Rich results include star ratings, FAQs, how-to steps, product prices, and event dates shown directly in the search results. Pages without schema miss out on these.
Broken schema is just as bad. It sends confusing signals to Google and stops your rich results from appearing.
How to check it: Use Google’s Rich Results Test. Paste your URL in, and it shows you which schema types are working and which have errors.
How to fix it: Add the correct schema type for each page. Use the FAQ schema for pages with question-and-answer sections. Use Product schema for product pages. Use the LocalBusiness schema for local service pages. Fix any errors flagged by the Rich Results Test.
10. No Mobile Optimization
Google uses mobile-first indexing. That means Google primarily looks at your mobile version of the page to decide how to rank it.
If your mobile experience is poor, your rankings will reflect that, even for desktop searches.
Common mobile issues include:
Text that is too small to read without zooming. Buttons and links are placed too close together to tap accurately. Content wider than the screen that forces horizontal scrolling. Intrusive popups that cover the main content. Missing viewport meta tag.
How to check it: Open your site on a real phone. Also, use Google’s Mobile-Friendly Test tool.
How to fix it: Use a responsive design that adjusts the layout to screen size. Set font sizes to at least 16px for body text. Make buttons at least 48px tall. Remove or reduce pop-ups on mobile. Make sure your viewport meta tag is set correctly.
A poor mobile experience also increases your bounce rate. When users land on a page that is hard to use on a phone, they leave immediately. Google tracks this behavior. A high bounce rate signals that your page is not giving users what they need, which pushes your rankings down further over time.
How to Audit Your Site for These Issues
You do not need to fix everything at once. Start with a structured audit.
Here is a simple process:
Run a Screaming Frog crawl to find broken links, duplicate content, missing title tags, and redirect chains. Open Google Search Console and check the Coverage report, Core Web Vitals, and the Performance report for cannibalization signals. Test your page speed with PageSpeed Insights. Check your mobile experience with Google’s Mobile-Friendly Test. Use the Rich Results Test to verify your schema markup.
Work through the list by priority. Fix technical issues first. Then move to content quality and internal linking.
Once you complete the audit, document everything. Keep a spreadsheet of issues found, who is responsible for fixing them, and their current status. This keeps the process moving and ensures nothing gets missed.
