Getting your website to rank on Google isn’t just about having great content. You also need to avoid the common SEO mistakes that silently sabotage your website, costing you rankings, traffic, and sales. Even small technical or content missteps can have a big impact on overall website performance.
If you’ve noticed a sudden drop in search traffic or aren’t getting the results you expect, you may be making one of the top five most common SEO mistakes.
In this guide, we’ll cover five common SEO mistakes and how to fix them.

The first common mistake is ignoring the technical side of SEO and website performance. In the early days of the internet, search engine rankings were determined in large part by the number of times keywords were mentioned on the page. This led website owners to stuff pages with relevant keywords, or even to pull tricks like repeatedly writing in the keyword at the bottom of the page in a color that matched the website background.
Keywords are still an important part of SEO, as we’ll see when we cover the second common SEO mistake. But search engine algorithms have moved beyond keywords to focus on website performance, which is impacted by technical SEO.
The most common technical SEO mistakes include:
All of these issues negatively affect the user experience and make it more difficult for web crawlers to crawl your webpages and understand your content.
We typically recommend that our clients use a variety of tools—including Google Search Console, PageSpeed Insights, and Screaming Frog—to first identify and then correct technical SEO issues. You may be able to fix some of these issues without a developer, but others will likely require technical expertise.
We also recommend that our clients perform regular site audits, which help them proactively identify and fix issues before they become major problems.
As we previously covered, keywords are still a critical part of SEO. It’s important to identify the right keywords to target for each page, include a mix of popular keywords, and make sure your pages aren’t competing against one another.
We typically recommend that our clients use tools such as Ahrefs or SEMrush to do keyword research and identify what terms their potential clients are searching for online. We’ve found that keywords often aren’t what clients expect, or that they discover new keywords to target.
When choosing keywords, it’s important to evaluate how competitive they are. Some keywords are very competitive, and it may not be realistic for your new or smaller site to try to compete with the heavy hitters on these very competitive or valuable keywords. There are often other similar keywords you can target that may get less traffic but are easier to rank for.
As an example, the keyword “insurance broker” is highly competitive and difficult to rank for. However, terms like “insurance broker vs. agent” or “licensed insurance agent [State]” may be easier to rank for and still bring valuable traffic to your website.
Common keyword issues include:
We usually recommend that our clients use a variety of free and paid keyword research tools, including Google Keyword Planner, Ubersuggest, AnswerThePublic, SEMrush, or Ahrefs. You should focus on high-intent, relevant keywords that are reasonably competitive, but not so competitive as to prevent your content from ranking.

Popular search engines including Google and Bing reward original and engaging content that’s helpful to users. They’re also prioritizing longer pages with more in-depth content. That means that if you’re putting out lots of thin, repetitive, or duplicate pages, they won’t rank well on search engine results pages (SERPs).
Common content issues include:
We recommend that our clients perform a site audit to identify duplicate content, low-quality content, and non-performing pages. Pages should be expanded or consolidated as necessary, with a focus on creating value for users by answering questions, solving problems, and offering valuable insight.
Tools like SEMrush can help you identify duplicate page descriptions, while Google Analytics shows which pages are underperforming in terms of traffic.
On-Page SEO or On-Site SEO involves optimizing individual web pages to improve their search rankings. It includes both content and technical SEO. Skipping On-Page SEO is a great way to ensure that your pages won’t rank, no matter how good they are.
Common On-Page SEO mistakes include:
We recommend that our clients do a site audit and ensure that every page has a clear title tag, meta description, and properly structured headings. Tools like SEMrush and Ahrefs can help you identify and correct On-Page SEO issues.
Websites are never truly complete, and ongoing SEO is essential to website performance. Search algorithms are constantly evolving, competition changes, and strategies that worked six months ago may not work today.
What failing to monitor and adjust SEO looks like:
We recommend that our clients track their website performance regularly using tools like Google Analytics and Google Search Console. A good ongoing SEO strategy involves performing regular site audits, updating outdated content, testing new keyword strategies, and making improvements based on data.

You’ve built a beautiful website with great functionality. You might be wondering, “what’s next?” or “how can I get more traffic?” The answer to that is in building and following a good SEO strategy, including regularly updating content, using On-Page SEO, and making sure that your website is configured correctly.
For a busy business owner, that can be a lot to manage. Lots of companies hire SEO consultants to help them manage their websites and execute their SEO strategy. However, that comes with risks, too. It’s easy for companies to set themselves up as SEO consultants online without having a deep understanding of current SEO strategies. We’ve also come across SEO consultants who focus entirely on keywords and ignore the technical side of SEO.

The top SEO errors to avoid include neglecting technical SEO, targeting the wrong keywords, and not creating a mobile-optimized website.
Some of the most common SEO mistakes include ignoring keyword intent, having poor on-page optimization, neglecting technical SEO, and not using internal links.
We recommend using tools like Google Search Console, PageSpeed Insights, SEMrush, Ahrefs, or Screaming Frog to identify technical errors and content issues.
Improving SEO or fixing SEO mistakes can improve your rankings and user engagement. Even fixing a few key issues like improving page speed or optimizing meta tags can lead to noticeable improvements.
The most common reasons your website isn’t ranking include targeting the wrong keywords, neglecting technical SEO, and putting out poor-quality content that isn’t engaging for users.
Keyword intent is the intention behind why a person is searching for that specific term. Not all keywords will be equally useful for your business. Some users might be looking to buy, while others are simply looking for information.
Keyword intent is important for SEO because you need to make sure you’re bringing the right people to your website. You want someone who’s ready to buy, not a college student doing research for a class.
There are four main types of keyword intent:
For your business, transactional intent users are the most valuable because they’re ready to convert. But your website should have a mix of keywords targeting all four types of user intent because some of those other users might convert as well.
Popular search engines like Google use mobile-first indexing, which means that non-responsive sites don’t rank as well. This makes mobile-friendliness an important part of good SEO.
We recommend that you start by identifying the SEO issues using tools like Google Analytics, Google Search Console, Ahrefs, or SEMrush. Then, take whatever issues you identified using those tools and correct them. Some of the fixes may require programming expertise.
We recommend that our clients perform an SEO audit every quarter. However, if you’re running a campaign or actively publishing content, we recommend doing a monthly audit.
Our best beginner SEO tips are to start by researching SEO and learning about current SEO strategies. We also recommend paying attention to technical SEO, as it’s an area that is often neglected.
Your website traffic could be dropping for a variety of reasons, including shifts in your competitors’ SEO strategies, changes to Google’s search algorithms, and errors on your website. We recommend using tools including Google Analytics, Google Search Console, SEMrush, and more to identify why your traffic is falling.
We recommend using SEO tools to identify SEO issues and underperforming pages and then fix the issues you’ve identified. We also recommend doing quarterly SEO audits to ensure that your website continues driving traffic and sales.
Your SEO might not be working for a variety of reasons. You could be targeting the wrong keywords, your website could have technical issues that are killing your rankings, or you could be following the wrong SEO strategy.
The fastest ways to tank your SEO performance are to neglect technical SEO, neglect On-Page SEO, and to create low-value content.
Having a poorly optimized website or neglecting SEO best practices harms website traffic and lowers sales.
We recommend that our clients start with free tools like Google Search Console, Google Analytics, PageSpeed Insights, and Screaming Frog (free version). Paid SEO tools like Ahrefs, SEMrush, and Moz offer deeper insights and are a great choice for larger companies with more extensive SEO needs.
