7 SEO Mistakes You’d Never Think to Check (And Why They’re Wrecking Your Rankings) 

Most SEO advice is fairly simple: write good content, use relevant keywords, get backlinks, and build a sitemap. It’s all solid advice, but there are often smaller details that get overlooked, especially when it comes to local seo.  

These are the kinds of mistakes many small businesses don’t even realise they’re making. They aren’t major design flaws or technical disasters, but they can quietly hold your website back from ranking as well as it could. 

Sometimes it’s a subtle technical issue or a missed opportunity. Sometimes it’s simply because no one has explained how SEO really works beyond the basics, but that’s why we’re here to help.  

Here are seven commonly overlooked SEO mistakes we see time and time again, and how fixing them can help your website perform better in search. 

1. Your site has a www and non-www version, and Google is indexing both

This one surprises almost everyone. In fact, it’s one of the most common SEO issues we come across because it’s so easy to miss, and no one even knows it exists.  

Type your website address into a browser with “www” at the front and then type it without. Do both versions load? If they do, Google may be treating them as two separate websites, which is then splitting your authority, duplicating your content, and ranking neither version as strongly as it should. 

Think of it like this: every backlink pointing to “www.yourbusiness.com.au” is building authority for one version. Every link pointing to “yourbusiness.com.au” (without the www) is building it for another. Instead of one strong site, Google sees two weak ones.  

The solution is simple. A developer can set up a permanent redirect so that one version always points to the other. It takes a developer about ten minutes to implement, yet most sites that have been around for more than a few years haven’t done it, and this small issue can quietly limit your rankings over time. 

2. You’re Competing Against Yourself 

If you are writing about the same topic more than once in your blogs on your website, for example, “Melbourne accounting for tradies,” or three service pages that overlap significantly, Google must decide which one to rank. Google doesn’t like to make difficult decisions, so when Google can’t choose, it often ranks neither. 

This is referred to as keyword cannibalisation, where your pages are fighting against each other for the same search, splitting the ranking signals that should be concentrated on one strong page. 

A business that’s been adding content over several years without a clear strategy often ends up with five pages that all vaguely target the same terms. Each one dilutes the others. The solution is to combine overlapping content into one definitive page, then redirect the others to it. One strong page almost always outperforms three weak ones, and the combined authority of the redirected pages flows to the one that remains. 

3. Your Images Are Slowing You Down, and You Don’t Know It 

You have a photographer who uploads their portfolio to you in the highest resolution, then your employee who adds a product image straight from their iPhone. Finally, your web designer finds a hero stock image without compressing it first.  

Every oversized image adds load time to your website. On mobile, load time is a ranking factor. Google’s PageSpeed Insights will tell you exactly which images are the problem, and most of them can be compressed without any visible quality loss using a free tool like Squoosh or TinyPNG. 

This common reason often goes very unnoticed if you are not on top of this from the get-go, and it can heavily affect a ranking.

4. Your Google Business Profile Category is Wrong   

Most businesses set their Google Business Profile category when they first create the listing and never revisit it. But the primary category is one of the strongest local seo ranking signals Google uses. 

“Consultant” ranks very differently from “HR Consultant.” “Contractor” ranks very differently from “Commercial Electrician.” A slightly wrong category can push you out of the local results for the searches that matter most, and it’s not because your business isn’t relevant, but because Google is reading the wrong signal. 

Check your primary category and then check what category your top-ranking competitor is using. 

5. You Have Pages Google is Quietly Not Indexing

If a page isn’t in Google’s index, it effectively doesn’t exist as far as Google Search is concerned. It might be live on your website and visible to anyone with the link, but if Google hasn’t indexed it, it can’t appear in search results. 

There are several reasons this happens, and most of them go unnoticed. 

A developer may have added a “noindex” tag while the website was being built to stop unfinished pages from appearing in search, then forgotten to remove it before launch. A page might be blocked in the robots.txt file, a technical file that tells search engines what they can and can’t crawl, because someone copied a template without realising the impact. 

Sometimes the issue is simpler. A page may have so little content that Google doesn’t consider it valuable enough to index. Or it may be a brand-new page that hasn’t been linked to from anywhere else on the website, meaning Google’s crawlers have never discovered it. 

The result is the same in every case: if a page isn’t indexed, it has virtually no chance of appearing in Google Search, no matter how good the content is. The page looks normal to you and broken to Google. 

Go to Google Search Console, open the Coverage report, and look at the “Excluded” list. There’s a reasonable chance pages you think are live: service pages, location pages, recent blog posts, aren’t being seen by Google at all. It’s one of the most common findings in an SEO audit, and one of the most surprising to the business owner. 

6. Your SSL Certificate Expired, And Google Noticed 

HTTPS is a ranking signal. Google gives a small but real preference to secure sites. SSL certificates expire, which is usually after one or two years,  if they’re not set to auto-renew. 

When a certificate expires, browsers show a security warning to visitors. Visitors will leave immediately, and  Google notes the experience signals. Rankings will then slip, and most business owners only find out when someone tells them the site looks broken. 

Check when your SSL certificate expires. If it’s not set to renew automatically, set a calendar reminder six weeks before it does. 

7. You’re Targeting The Whole Country When You Only Serve One City 

If your business is based in Melbourne and you only work with clients in Melbourne, you shouldn’t be trying to rank nationally. The competition is much broader, with thousands more businesses competing for the same keywords, making it significantly harder to achieve strong rankings. 

Even if you did manage to rank nationally, much of that traffic would be irrelevant. Visitors from other states are unlikely to become customers if you don’t offer your services there. 

Local SEO is a different, much simpler ball game. “Family lawyer Geelong” is more achievable than “family lawyer.” “Physiotherapist Collingwood” is more achievable than “physiotherapist Victoria.” The more specific the location, the less competition and the more qualified the visitor. 

Most small businesses are accidentally targeting their business on a national or statewide scale, where it doesn’t matter, because no one has noticed or deliberately narrowed their focus in their keywords. The service pages say “we help businesses across Australia” when the business has never taken a client outside Victoria. That language signals to Google that the site is competing nationally, and nationally, this small business has no chance. 

A few changes to page titles, headings, and content can shift a site from competing nationally against thousands of pages to competing locally against dozens. The visitor who finds you after searching “Eyebrow threading and tint Melbourne” is also a significantly more qualified lead than one who found you searching “Eyebrow thread” from anywhere in the country. 

What These Mistakes Have in Common  

None of these mistakes is obvious. They don’t jump out when you look at your website, and most have likely been there since the site was first built. 

That’s what makes them so costly, as it’s rarely one major issue holding a website back. Instead, it’s a collection of small technical and strategic mistakes that quietly compound over time, leaving many businesses wondering why their SEO never seems to gain traction. 

The good news is that most of these issues can be fixed in an afternoon once they’re identified; however, finding them is the difficult part. 

Go back through this list and work your way through each point. Even fixing one or two of these issues can make a noticeable difference over time, and together they can have a much bigger impact than most businesses realise.
