Understanding SEO: A Developer’s Guide to Search Engine Optimisation
The world of web development is intricate and multifaceted, combining creativity, logic, and now more than ever, marketing principles. As you graduate from Northcoders, you're entering a dynamic landscape where development skills alone aren't enough. One area where marketing and development intertwine is Search Engine Optimisation (SEO) so I thought we'd take a technical look at SEO, understanding its mechanics, and exploring why you, as developers, must consider these principles when building web pages.
What is SEO?
SEO stands for Search Engine Optimisation, a practice that involves optimising a website to increase its visibility in search engine results. Essentially, it's about making your web pages more attractive to search engines like Google, thereby increasing organic (non-paid) traffic.
How Does SEO Work?
- Crawling and Indexing: Search engines use bots called crawlers to find and read web pages. They then index these pages, storing information about them in massive databases. As developers, ensuring your site is crawlable and indexable is vital. I wish I had a pound for every time a site went live and developers hadn't made it visible to search engines.
- Ranking Algorithms: Search engines use complex algorithms to rank indexed pages based on various factors. These algorithms consider aspects like relevance, quality of content, user experience, internal links and many more.
- On-Page and Off-Page SEO: SEO can be categorised into on-page (elements you control on your website) and off-page (external factors like backlinks). Both contribute to how a page ranks.
Key SEO Principles for Developers
- Mobile Optimisation: With the increasing use of mobile devices, making sure your website is responsive to different screen sizes is essential.
- Site Speed: Slow-loading pages can negatively impact user experience and SEO ranking. Optimise images, leverage caching, and minimise code where possible. If you are running a wordpress site for instance, have a look at hosting on OpenLiteSpeed to really speed up your website.
- Semantic HTML: Using proper HTML tags (like <h1>, <h2>, etc.) helps search engines understand your content structure.
- Meta Tags and Descriptions: These provide search engines with information about your page's content. Using relevant keywords and clear descriptions can enhance visibility.
- URL Structure: Structuring URLs to be descriptive and include keywords can improve SEO.
- Implementing Structured Data: Structured data helps search engines understand your content better, enhancing how it's displayed in search results.
- Avoiding Duplicate Content: Duplicate content confuses search engines. Implement canonical tags to specify the primary version of a page.
- Secure and Accessible Website: Having an SSL certificate (resulting in HTTPS in your web address) is a known ranking factor.
- Internal Linking: Strategically linking to other relevant pages on your site helps search engines navigate your website and understand content relationships.
- Regular Updates and Quality Content: Keeping your site updated with quality content signals to search engines that your site is alive and valuable.
Why Should Developers Care About SEO?
Understanding and implementing SEO isn't just a marketer's job. As developers, your coding decisions directly impact SEO. Collaborating with marketing teams and aligning your development practices with SEO principles ensures that your web pages are not only functional but also discoverable.
Moreover, as technology evolves and search engines become more intelligent, the technical aspects of SEO will grow in complexity and importance. Your ability to adapt and integrate these principles will become an essential part of your toolkit.

Is AI replacing Software Engineers?
Artificial-intelligence chatbots such as OpenAI’s ChatGPT have made a lot of noise this year. These impressive AIs can hold conversations, draft essays, and even write and debug code, all in a matter of seconds. But if AI is so efficient, could it replace Software Engineers entirely, especially those at a more junior level?
