12 SEO Issues You Can't Ignore on Your Website

By Michael Delpierre, CEO, Conversion Pipeline First published February 10, 2020. Rewritten and updated October 2026.

It's easy to get caught up in running the business and let the website drift. Then one month the phone gets quieter, form fills drop, and nobody can say why. When we open Search Console on a site like that, the cause is usually not a Google penalty or some mysterious algorithm update. It's a handful of ordinary technical and content issues that piled up over a few years.

We've been running SEO audits for service businesses, B2B companies and local contractors since 2009, and the same problems keep coming back. This list is the order we work through them, starting with the ones that stop a page from ranking at all.

1. Important pages aren't indexed

If Google hasn't indexed a page, it can't rank. That sounds obvious, but we regularly find service pages and location pages sitting in Search Console under "Crawled, currently not indexed" or "Discovered, currently not indexed" for months.

Not every URL should be indexed. Thank you pages, filtered URLs, internal search results and old duplicates are fine to leave out. The question is whether the pages you actually want customers to find are in the index.

The usual causes:

• A noindex tag left on after a redesign or staging launch
• A canonical tag pointing to a different URL
• Thin or near duplicate content that Google decided wasn't worth keeping
• No internal links pointing to the page
• Server errors or slow responses during crawling

How we check it: open the Pages report in Search Console, filter to your sitemap, and use URL Inspection on the pages that matter. Google's crawling and indexing documentation explains each status. A sitemap helps Google find URLs, but it never guarantees indexing.

2. Robots.txt and sitemap mistakes

Robots.txt controls crawling. An XML sitemap lists the URLs you want discovered. They do different jobs, and mixing them up causes trouble.

Things we find on a regular basis:

• A Disallow: / rule copied over from a staging site
• Blocked CSS or JavaScript, so Google can't render the page properly
• Sitemaps full of redirected, 404 or noindexed URLs
• Important pages missing from the sitemap entirely
• A staging subdomain that is still crawlable and competing with the live site

Also worth knowing: blocking a URL in robots.txt does not reliably keep it out of the index. If you want a page gone from search results, use a noindex tag and let Google crawl it.

3. Duplicate content and confused canonicals

When several URLs show the same or nearly the same content, Google has to pick one. It doesn't always pick the one you want.

Common sources are HTTP and HTTPS versions, www and non www, trailing slash variations, URL parameters, printer friendly pages, and location pages where only the city name changes. Blogs create their own version of this when an older post and a newer post target the same topic with almost the same title.

The fix: pick one preferred URL for each piece of content, redirect the rest where you can, and use a self referencing canonical tag on the version you keep. Google's guide to canonicalization covers the details. If two pages compete for the same search, merging them into the stronger URL usually beats keeping both.

4. Redirect chains and broken internal links

A redirect chain happens when Page A redirects to Page B, which then redirects to Page C. They build up quietly over years of redesigns, platform moves and renamed URLs. Each hop slows users and crawlers down, and the longer the chain, the more likely it eventually ends somewhere irrelevant or on a 404.

Broken internal links are the close cousin. A page gets deleted or renamed, and the menu, footer or old blog posts keep linking to the dead URL.

The fix: crawl the site, then point every redirect straight at its final destination and update internal links to the current URL instead of relying on redirects. If a page is gone with no real replacement, a clean 404 or 410 is fine. Redesigns are where most of these start, so our list of SEO mistakes to avoid during a website redesign is worth a read before your next one.

5. Slow pages

Speed alone won't make a page rank, but a slow page loses visitors before they ever see your offer, and Core Web Vitals are part of how Google looks at page experience.

The biggest culprits on the sites we audit are oversized images, stacks of third party scripts (chat widgets, heatmaps, old tracking tags nobody removed), heavy page builders and cheap hosting.

Run your key pages through PageSpeed Insights and look at the field data, not only the lab score. Fix the largest image and the slowest script first. That usually gets most of the gain.

6. Mobile layout problems

Google indexes and ranks the mobile version of your site. If the mobile page hides content, has buttons too close to tap, or scrolls sideways because something is wider than the screen, that's the version Google is judging.

We test every important template on an actual phone, not just a resized desktop browser. Watch for:

• Text too small to read without zooming
• Content that runs wider than the screen
• Click to call buttons that don't work
• Forms that are painful to fill out on a phone
• Content or schema that exists on desktop but not on mobile

Google's mobile first indexing best practices lay out what has to match between the two versions.

7. Weak, missing or duplicate title tags and meta descriptions

The title tag is still one of the strongest on page signals, and together with the meta description it's what people see in search results before they decide to click.

Problems we see constantly: every page titled "Home" or just the company name, the same title on dozens of pages, titles cut off halfway because they run too long, and meta descriptions that were never written so Google pulls random text.

Write a unique title for each page that says what the page is and who it's for, and keep it to roughly 60 characters. Treat the meta description as a short pitch for the click. Google may rewrite either one, but it rewrites good ones far less often.

8. Missing or muddled H1s and headings

Your H1 should tell a visitor, in plain words, what the page is about. A page with no H1, or with an H1 that just says "Welcome," misses an easy chance to make the topic clear.

One correction to advice you may have read elsewhere: more than one H1 on a page is not an automatic penalty. What matters is a logical structure. For most service pages and articles that means one clear H1, H2s for the main sections, and H3s underneath where they help. Write headings for readers, not as a place to repeat keywords.

9. Structured data errors

Structured data (schema markup) helps Google understand facts about your business and your pages, such as your name, address, phone number, services, reviews, FAQs and articles. Done well, it can make a page eligible for richer search results.

Done badly, it does nothing or worse. We often find schema with the wrong business type, an old address, review markup that breaks Google's guidelines, or syntax errors that make the whole block invalid.

Test your key pages in Google's Rich Results Test and check the Enhancements reports in Search Console. Only mark up what is actually visible on the page.

10. Thin or outdated content

A service page with three generic sentences rarely ranks for anything competitive. Neither does a city page that is a copy of twenty other city pages with the name swapped. Google wants to see that a real business with real experience wrote the page.

The pages that earn rankings for our clients usually answer the questions customers ask on sales calls, show real projects or results, explain pricing factors honestly, and make it obvious who is behind the advice. That's also what AI search features tend to pull from. We wrote more about why content is still central to SEO.

Older posts need attention too. Statistics go stale, tools get renamed (Google My Business is now Google Business Profile), and old advice stops being true. Update the content when something has genuinely changed. Don't just change the date. If you serve a specific area, keep your Google Business Profile and location pages current as part of the same routine. Our local SEO team handles that side for many of our clients.

11. Weak internal linking and orphan pages

Internal links are how both visitors and Google find their way around your site. A page with no internal links pointing to it, an orphan page, is hard for Google to find and tells it the page probably isn't important.

Link blog posts to the service pages they relate to, link related articles to each other, and link parent service pages to their child pages. Use descriptive anchor text such as "SEO services" instead of "click here." A quick crawl will show which important pages have one internal link or none.

12. Tracking rankings instead of leads

Plenty of businesses watch keyword rankings and traffic and never connect either one to revenue. That makes it impossible to tell whether SEO is working or which pages are worth improving.

At a minimum, set up Google Search Console, Google Analytics with real conversion events, and call tracking if the phone matters to your business. Then look at leads by landing page, not just sessions. If your form fills or calls aren't recorded properly, start with our list of common conversion tracking problems.

This matters more now that AI answers sit on top of many search results. Clicks and rankings tell less of the story than they used to, a shift we covered in Google's biggest search change in 25 years.

Small SEO issues add up

Whether you run a plumbing company, a real estate agency, an accounting firm, a dental office or a moving company, it's easy to push SEO maintenance down the list. None of these 12 issues will sink a site overnight. Together, left alone for a couple of years, they quietly drain organic leads, and nobody notices until the pipeline is thin.

Most of them are fixable in days, not months, once you know where they are. If you're on Webflow or WordPress and weighing a platform change, our Webflow vs WordPress comparison covers how each platform handles the technical basics. For home service businesses, these same problems show up in our list of the biggest mistakes contractors make online.

Frequently asked questions

What are the most common SEO issues on business websites?

In our audits the most common are important pages that aren't indexed, duplicate or weak title tags, redirect chains and broken internal links left over from redesigns, slow mobile pages, thin service pages and missing conversion tracking.

How often should I check my website for SEO issues?

Look at Search Console at least monthly and run a full technical crawl every quarter. Always run one right after a redesign, a platform migration or a large batch of URL changes, since that's when most problems start.

Can I fix SEO issues myself?

Many of them, yes. Title tags, meta descriptions, internal links and content updates are manageable for most site owners. Indexing problems, canonical conflicts, redirects and structured data are easier to get wrong, and that's where an audit pays for itself.

Do multiple H1 tags hurt SEO?

Not by themselves. Google has said multiple H1s are not a problem. A clear heading structure with one obvious main heading is still the better practice for readers.

How long does it take to see results after fixing SEO issues?

Technical fixes such as indexing and redirects can show up within a few weeks once Google recrawls the pages. Content improvements usually take longer, often two to four months, depending on competition.
