5 Website Mistakes That Are Killing Your Google Rankings
If your website isn't ranking where you think it should, there's a good chance one of these five mistakes is the reason. They're incredibly common — and they're found on the majority of small business websites we scan.
The good news: all of them are fixable. Once you know what to look for, most can be corrected in an afternoon.
Mistake #1: Missing or Duplicate H1 Tags
The H1 is the main heading on a page. It's the single most important on-page signal that tells Google (and visitors) what a page is about.
Two mistakes are common here:
- Missing H1: The page has a visual headline styled with CSS, but it's not marked up as an H1 in the HTML. Google doesn't read design — it reads code. If your heading isn't an H1 tag, Google doesn't treat it as the page's primary topic signal.
- Multiple H1s: Having two or three H1 tags on the same page dilutes the signal. Use exactly one H1 per page, and make it count — it should clearly include your target keyword.
How to fix it: Right-click your page, select "View Page Source," and search for "h1". Make sure there's exactly one, it contains a meaningful description of the page, and it includes your target keyword.
Mistake #2: No Meta Description (or a Duplicate One)
When your page appears in Google search results, the text snippet beneath the link is your meta description. It's not a direct ranking factor — but it heavily influences whether people click your result.
Pages without a meta description let Google choose its own — which is almost always worse than a human-written one. Pages with duplicate descriptions (the same text copied across multiple pages) give Google no useful signal about what makes each page unique.
Every page needs a unique, well-written meta description of 150–160 characters that includes your target keyword and gives a clear reason to click.

Mistake #3: No XML Sitemap (or One That's Never Been Submitted)
A sitemap is a file that lists every URL on your website. Submitting it to Google Search Console tells Google exactly what pages exist on your site and helps new content get indexed faster.
Without a sitemap, Google discovers your pages by crawling links. This works eventually — but it's slower, and some pages might never get discovered, especially if they're not well-linked.
How to fix it: Generate a sitemap (most CMS platforms do this automatically, or you can use a free sitemap generator tool), then submit it in Google Search Console under Sitemaps.
Mistake #4: Render-Blocking Scripts
JavaScript and CSS files loaded in the wrong place can prevent your page from displaying content until they finish loading. This is called "render-blocking" — and it's one of the most common reasons websites score low on Google PageSpeed Insights.
Visitors don't see a blank screen for a few seconds while your analytics script loads. They see a blank screen and hit back.
Render-blocking scripts are flagged in Google PageSpeed Insights as a specific issue. On WordPress, the Autoptimize plugin can defer most scripts automatically. On other platforms, your developer can add "defer" or "async" attributes to script tags.
This is closely related to overall page speed — which directly affects both rankings and bounce rate.
Mistake #5: Broken Internal and External Links
Broken links are pages that no longer exist — they return a 404 error. Every broken link on your site:
- Wastes Google's crawl budget (it follows links that lead nowhere)
- Dilutes your site's "link equity" — the ranking power passed through internal links
- Frustrates visitors who click them, increasing your bounce rate
- Signals to Google that your site isn't well-maintained
Broken links accumulate silently over time. You delete a page and forget to update links pointing to it. An external site you linked to changes its URL. A plugin creates pages that you later remove.
How to fix it: Use a broken link checker tool or run an automated site scan. For each broken internal link, either restore the page, redirect the old URL to a relevant existing page, or update the link to point somewhere useful.
How Many of These Does Your Site Have?
Most sites have at least two or three of these issues. The tricky part is that they're invisible — you can't spot them by browsing your site. You need to look at the underlying code and run diagnostic tools.
If you haven't done a thorough check recently, start with a comprehensive review of why your site might not be showing up on Google — and run a free scan to get a complete picture of what's holding you back.
