SEO - 10 Common Mistakes to Avoid

Updated: Jul 26, 2021

The grind of search engine rankings can be tedious, and often a maze of technical confusion for the uninitiated.

We've managed the SEO for many websites over the years, and continue to add to that roster every day. Upon analysing each of these websites we've compiled a list of the most common SEO issues and mistakes that we've come across.

While some issues can harm your overall SEO, others are just reminders that you could improve certain elements to make your website more discoverable to search engines.

Not sure what SEO really is? Need a quick guide to give you the basics? Check out our previous article about what SEO is and why you need it.

So, let's dive in, and discover what problems you'll most likely have with your website's SEO and learn how to fix them.

common SEO mistakes to avoid

1. Images with missing alt text

This is, without a doubt, the biggest shared SEO issue we encounter. But why is missing alt text for images a problem at all?

The thing is, while Google is very good at understanding text on a page, it has a much harder time deciphering what's in an image.

Alt text (alternative text) is an HTML element designed to explain the meaning of images to search engines as well as make them more accessible to users.

In 2018, Google Images’ search was the second biggest search channel, falling right behind the classic Google SERP. In fact, alt text is one of the main elements of image optimization and your ticket to getting your pictures associated with the proper keywords. This is especially important for eCommerce websites, since each offered item is illustrated with an image.

In short, alt texts help search engines better understand and rank your images.

Alt text also comes in handy for users when the picture doesn’t load up for some reason, and also for people with impaired vision who have trouble perceiving visual information.

The only reason missing alt text is a problem for most websites is because it requires additional time and effort. Most website owners simply overlook this issue, or have no idea it's required, due to the fact that many CMSs don’t provide the option of adding alt texts by default. In such cases, you need to manually add the tag to the HTML code of your pages.


2. H-tags just being weird

Although Google claims that the H1 tag is not that critical for SEO, H-tags are still very appreciated by users since they help them scan content and enhance the reader experience.

H1 tags help both search engines and users understand what the page is about at a glance. While H2 tags help structure the content of the page and make it easier to scan the page within several seconds. Your blog articles or product landing pages will most likely require H1 and H2 tags.

Also, pay attention to duplicate H1 tags. They can confuse search engines or make your pages compete for the same keyword. But if your H1 tags duplicate headings of supporting pages or pages of different language versions — it’s definitely not something to worry about.

Here’s the main takeaway from H-tags: Everything that makes your pages better for users makes a difference to Google. Besides, properly optimized H-tags help Google extract information from your page for Featured Snippets (selected search results that are featured on top of Google's organic results below the ads in a box).

So, when you see H-tag problems on your website, the first thing you should look at is the page that has these issues. If it’s a target page in your SEO strategy, then, of course, you need to take it seriously to keep your H-tags spotless, as in no empty tags, no duplicates, and properly optimized.


3. Pages with a low word count

Over two thirds of website pages we encounter have fewer than 250 words. Now, it's important to mention that there are different types of websites, with different functions, and, website galleries won’t have lots of text content on most of the pages — just a caption for each image.

But not all websites are galleries.

If your website has empty pages (or almost empty) then ask yourself if it's necessary, or if can easily be added to another page. After all, why would you need a page that contains nothing? Even if your main content is media files, they still need some text to accompany them, because that’s what search engines understand best.

If you have pages with a low word count, check whether you need them at all. And if you do, expand their content to get a higher ranking, or, work them into another page that may also need content. If it's a page you don't need, just delete it.


4. Missing or empty meta description

Even though Google sometimes use the description meta tag for snippets, they still don’t use the description meta tag in their rankings.

Should we then forget about it? No! We should focus on Google using “the description meta tag for the snippets” part.

Since it’s largely used for snippets in Google’s SERP, the meta description affects the CTR (click through rate) of our links featured in search results. If optimized properly, the main keywords will be highlighted in the description, which signals to the user that this page is what you are looking for.

Think of it this way: Stop thinking about meta descriptions as a ranking factor, and start thinking about them as a conversion factor - Neil Patel.

Using plugins helps remember to add a description tag to the pages you are promoting. For example, for WordPress websites, you can use the Yoast plugin. It includes a snippet editor in your admin panel, where you can check whether or not the length of your description is fine and does, in fact, include the target keyword. For WIX, these SEO tools are already built in, offering a seamless SEO implementation for your website.


5. Pages with no inbound internal links

One issue that's quite worrying to see is that almost half of all websites have pages with no links connecting it to other internal website pages. Internal links serve three important goals:

  1. They enable users to navigate your website. With no inbound internal links to a page there is no chance users will find it.

  2. They help structure the website content hierarchy. By leading users link by link from page to page, you are pushing them to follow your predefined conversion path.

  3. They help distribute links across the website.

Having pages without internal links can be justified, for example, if you create a landing page for a particular promo campaign such as Black Friday, Christmas sale, and so on. Such pages only exist during the period of the sale. As a rule of thumb, people can find this landing page by following the link posted on social media or sent in a newsletter, so there’s no need to have links leading to them from other website pages.

It’s quite simply bad form to have isolated pages from an SEO perspective. Search engines won’t find them while scanning your website, and users won’t get there when browsing your site.

The question is, why would you need to have a page like this at all?

If isolated pages are identified on your website, the first thing you have to do is decide whether the page is valuable. If so, revise your website structure and figure out the best way to build links to this page from other sections and pages of your website. By this we mean the way users and search engines can get to the page without applying extra effort.

If there’s no point in having the page, it’s better to delete it altogether.


6. External links with 4xx status

In most cases, a link with a 4xx status is a link that leads to a page with a 404 error, meaning it’s a broken link. This usually happens when the destination website removes the linked page or changes its URL without redirecting users to the new one. As a result, you have a link leading to nowhere, which is ridiculously annoying for users. Google also won’t appreciate you sending users to dead pages — if you have plenty of out-of-control links, it’s a signal to the search engines that your content may be outdated, and as such you'll start to fall down the rankings.

The thing is, if you don’t monitor your outbound link status, you won’t notice a dead link. So the best thing to do is to run a website audit regularly. This will allow you to identify broken links, then remove them or change them. Website SEO audits is something we do regularly, and at great length, so get in touch if you'd like to have an audit run on your website.

If right now you’re feeling a bit frustrated with the websites you link out to (why in the world do they keep error pages up without redirects?!) — hold on. There’s a big chance you also have 404 pages that you don’t know about.


7. Pages with 4xx response

Over a third of the website we've analysed have pages with a 4xx response. In most cases, a 4xx response appears for a 404 error, although having pages with the 404 error is not that terrible in itself. However, you should take care of every internal link to such pages. Linking out to dead pages within the website is much worse than having broken outbound links.

An internal broken link is one of the Four Horsemen of the “bounce rate” Apocalypse, so you need to either delete links to pages with the 404 error or set up a 301 redirect.

As was mentioned above, a page with a 404 response doesn’t harm your SEO directly, it’s all about links and user comfort. And to reduce user frustration as a result of seeing an error page, you should make your 404-page look awesome!


8. Frame is present

The problem is that most site owners don’t even know what a frame is, even though around 40% of websites IN THE WORLD have it.

The frame is an HTML element that lets you display the content of other websites on your own web page. In other words, it embeds a page within another page. The main purpose of the tag is to use a component of other websites’ content without duplicating it. For example, when embedding a YouTube video or a Twitter post (e.g. this BuzzFeed post has lots of elements embedded via iframe), gifs, or even a PDF file.

SlideShare uses iframes for presentations and Gmail uses the iframe-tag for many things, for example, to embed Hangout chats. Besides, with frames, we can insert tools for user analytics (e.g. Google Tag Manager) or dynamic maps into your pages.

The key negative thing about iframes is that you don’t control them. Your page’s CSS doesn’t apply to content within the iframe. So, if you embed the content of a malicious website, you can jeopardize not only your particular page but your entire website.

Having a frame tag means having several URLs on the same page, which can be confusing for search engines. Google does state that it doesn’t guarantee that they associate framed content with the page containing the frame.

Finally, framed content is terrible for user experience. The look and style of such elements are not adjustable, so most of them look awkward on the page. On top of that, framed content is not flexible for users — they can’t change their sizes and have to interact with them within a small framed region on the page. It’s also hardly adaptable for mobile users, which is no longer tolerated by search engines.


9. No redirect from HTTP to HTTPS page version

Since Google announced HTTPS to be a ranking signal, lots of websites moved to the secured protocol. Foremost, it was critical for websites storing and dealing with sensitive information (such as user's personal data, credit card details, etc.). Then, Google started marking HTTP websites as non-secure, which pushed more and more websites to transit to the secure version.

Today, statistics show that a third of websites have trouble redirecting users from HTTP to HTTPS.

But, why is this a big deal?

If you don’t set a correct redirection, you won’t get the boost promised by search engines for HTTPS websites. There’s also a chance that your pages will lose their ranking positions in the SERP.

What you should do is find every HTTP page you forgot to redirect to HTTPS. Google strongly recommends using 301 redirects on a URL by URL basis. It makes your migration plans clear to the search giant and shows that you’re doing everything the same way on your secure version as on the HTTP one: you have the same content, you 'no-index' the same pages, and set the same rules in the robots.txt file for both versions. This is what Google calls a clean migration.


10. Missing XML sitemap

An XML sitemap is a file with a list of all your website’s URLs and information about how they are related to each other. It helps search engines spot every page on your website, even isolated ones or those without links from other sites.

Technically, you don’t need an XML sitemap to get your pages indexed because search engines scan your website link by link. But there’s always a “but”.

First, are you sure your pages are linked properly and that Google will be able to find all of your pages by scanning them link by link?

An XML sitemap is a way to introduce all of your pages to search engines. Even if your website is a million-page e-commerce portal, it becomes an open book for Google if it has a sitemap.

Second, if your site is full of media content (images, videos, etc.) that you want to get indexed, adding them to your XML sitemap will speed up the process.

If your Website Audit found out that your website is missing the XML sitemap, you should generate it and submit it to Google.
