10 Common Website Development Mistakes That Hurt Your SEO


In this digital era, having a nice website is only half the equation; it should be optimized for search engines to drive organic traffic and help customers improve their rankings on Google.  Many brands make investments in the web development services process and don't even realize they are making  SEO mistakes which undermine their overall SEO strategy.  If your goal is to improve your online presence, you will want to steer clear from these common web development mistakes.

Web Era Solutions is an SEO agency dedicated to making SEO-friendly websites that look great and perform well in the SERPs. Continue reading for the 10 website development mistakes that will hurt your SEO and how to fix them.

1. Ignoring Mobile Responsiveness

Mobile devices make up over 50% of web traffic, along with Google favoring mobile-friendly websites. Therefore, if your website is not responsive, the visitors that are coming to your site via mobile will bounce more and cause less traffic overall.

Solution: Always build your website responsively for all kinds of devices your visitors may be using. You can test your site using Google's Mobile-Friendly Test.

2. Slow Page Loading Speed

Users leave websites that take longer than 3 seconds to load. Search engines view page speed as a direct ranking factor (some search engines do not take other additional page load factors into an account). This means that if your website is slow to load, it is going to be a struggle to rank it higher.

Assessment: Improve performance by optimizing images, particularly for the Internet; using either a CDN (content delivery network) or your own web server to deliver images to users; and enabling the browser to cache static files. Improve performance by compressing CSS files, JavaScript files, and HTML files.

3. Poor Website Architecture

Having a formal, complex, or unstructured on-site structure prevents search engines and bots from crawling and indexing pages accurately. It can also confuse users, which is not good for user experience.

4. Missing or Duplicate Meta Tags

Page titles and descriptions are really important for CTRs and rankings. If tags are missing, replicated or not written well it will limit visibility within search results substantially.

5. Not Using HTTPS

Google prioritizes secure sites. A site that is unsecure (HTTP) provides 1) a negative impact on your SEO, and 2) a lack of trust from your users. 

Solution: SSL certificate installation and having all pages served securely with HTTPS. Redirect old HTTP URLs to new HTTPS URLs.

6. Broken Links and 404 Errors

Both internal and external broken links can hurt user experience as well as search engine ranking. Broken links are a sign of your website not being in good shape. 

You should regularly perform a broken link audit on your website; you can conduct a broken link site audit with online broken link tools, such as Screaming Frog and Ahrefs. Fix broken pages or redirect any broken pages to a relevant page on your website.

7. Overusing JavaScript

JavaScript can provide functionality but can be used excessively and stop search engines from crawling and indexing your site correctly. This limits your site's visibility for its important content. 

The resolution is to ensure your key content is accessible in HTML, or server-side-rendered or pre-rendered, if you are heavily dependent on javascript.

8. Neglecting Image Optimization

Utilizing high-resolution, uncompressed images can hinder your loading speed, as well as your SEO for that matter. Notably, when you have a photo that does not use any alt tag information, search engines (including Google) have no clue what the image is or what it is showing. 

Solution: Reduce your images to a smaller file size while still keeping decent quality, and add alt tags to all images that accurately describe the image and use the project key phrase(s) for higher ranking. The latest image types, such as WebP, are so efficient they will decrease loading time.

9. Lack of Structured Data (Schema Markup)

Structured data can yield rich results (ratings, FAQs, breadcrumbs, etc.) in search engine results pages (SERPs) and make it easier for the search engine to interpret your material. If you do not implement structured data you will lose the added exposure, and real estate in SERP's.

Recommendation: Use schema markup that is relevant to your business such as LocalBusiness schema, Product schema, or Article schema and test your structured data implementations with Google's Structured Data Testing Tool. 

10. Poor Internal Linking

Internal links assist with navigation throughout your site, letting both spiders and people know your content hierarchy. If a well-planned internal linking structure does not exist, you cannot expect your pages to rank, and users may leave before they explore your site.

Solution: Connect relevant content on your site with a keyword-rich anchor text. Again, ensure that you factor your key pages to get more internal links to show relevance and authority.
