The top 10 SEO mistakes web developers make

As a web developer and an SEO specialist at the same time I find myself conflicted many times between both hats. As a web developer I care about clean code and easy ways to create new content, and as an SEO guy, I’m obsessed with the way Google indexes my website, internal linking, breadcrumbs and alt texts.

When I’m wearing the SEO hat, I’m the annoying guy asking my fellow developers if they followed all the SEO rules I gave them.

And since I too am a developer, I know they’re going to lie when they answer “yes of course”.

 

The 10 SEO mistakes web devs make

10. Alt tags and Titles

When one codes, it’s very easy to not fill in Alt texts for images and Title texts for links. Because sometimes we simply don’t know what they are. Ideally, they should be filled by an SEO specialist or a Digital Marketing guru. But they don’t have access to the code, or limited access to these fields in a CMS. That’s why web devs should always spend a second to wonder what the image or the link is about and write it in the appropriate location.

9. Rich Snippets and Structured Data

Rich snippets and structured data, AKA schema.org and microdata were launched in 2009 by Google and then 2011 by most Search Engines to improve the quality of the web. The idea is to tell Search Engines what’s in the content. For example, if we’re talking about a blog post, we should add a bunch of blog related microdata tags to our code. Here is a pretty good introduction to snippets and structured data and here is a review microdata generator .

8. Link Anchors

Click here and read more are not the best in terms or User Experience, and they’re definitely not the best for SEO! The anchor text of links tells Google (and your visitors) what the destination page is about. So when your anchor says “click here” no one really knows what’s going to happen. Link Anchors have a real importance in SEO and you should fill them with what the page is about (like I did in the present article).

7. Missing Meta (social media, languages,etc..)

Metas are not just for jquery and CSS. they contain a lot of information for bots to understand the website. Yes, the site works without them, but it’s also true that not optimizing them is a good way to miss opportunities in terms of Social Media and Search Engine presence. What you can do if you don’t know where is to start is wonder about what bots you care about, and what do they need. Facebook? Google? they all have different recommendations.

In any case, make sure your description is focused on your keyword AND the content of the page. You might also need robots and canonical to avoid duplicate content, title for SEO, language for SEO and accessibility, etc…

6. Pagination and Pages Variations

Pagination and Variation pages are bad for SEO since they basically have the same URL and the same meta for different content. They all cannibalize the same keyword. There are mainly two ways of dealing with this problem.

First Option: Embrace the difference. Make sure every page has different names and meta, basically, make them unique.

Option Two: Tell Google it’s page two or variation three or whatever the difference is. Use <canonical> to indicate what’s the main page (the first one) and pagination markup like <rel=”prev”> and <rel=”next”>. You can also add a “nofollow” to the link pointing to the next page and a “noindex” to the actual page.

Here is a great article about Pagination and SEO.

5. Duplicate Content

It’s not always on purpose but sometimes we just copy past content from a page to another, or we create a PHP script that generates a bunch of pages using the sane variable. Well, that’s duplicate content, and it is to be avoided at all cost.

4. Don’t care about URLs

There are many articles about how to construct URLs for SEO. Basically, they should be as simple as possible, and contain only words and dashes that tell users and bots what the page is about. I know URLs are convenient for passing an incredibly long list of variables and characters but if you can, please avoid it.

3. Use the wrong HTML tag

If you want something bold for design purposes, use a class, not the <strong>. Strong means it’s important. Sometimes we use HTML tags instead of classes because it’s faster. But bots and search engines use these tags to understand what matters and what doesn’t. <Strong> and <em> are actually important for SEO, the same way paragraph, section, aside, and other tags are important. Try to make sense, it will pay off.

2. Use Headings for style

Have you ever done that? Use H1 for every sub-title on a page? After all, they are titles and they have the same CSS style.

Bad idea.

Search Engines and bots use headings to understand the hierarchy of your content. If everything that you want big is a H1, then what do you have for h2 or h3? Even rankings don’t really use these anymore, it makes a lot of sense.

1. Robots and Sitemaps

Sometimes we forget. And Google indexes everything. And then when your SEO guy comes in and does “site:yoursite.com” in Google they find out that your development folder at the root of your website is nicely indexed with all of its content. Don’t laugh, it happens. And the problem is that it will take weeks, or months to fix it.

First, make sure you have a robots.txt file that excludes everything not public. Dev folders, sources, anything not public.

Then create a sitemap (if you’re on WordPress you can install Yoast SEO and it will do it for you). Once the sitemap is created, look at it! Make sure every page in there is useful and relevant.

Hint: the “hello world” post is not.

When you’re done, send it to Google and pray.
