Technical SEO

What is Technical SEO?


Technical SEO covers all the ways in which you can make it easier for search engines to crawl, index, and render your web pages.

In other words, it’s about making sure that your content is readable by search engines as well as humans.


It is also a significant part of creating a great user experience (UX) as people want to visit web pages that load properly and quickly and are easy to navigate.


How important is technical SEO?


In 2012, Google officially launched the Penguin ‘webspam algorithm update’, which specifically targeted link spam and manipulative link building practices.


In many ways, this algorithm was a turning point for SEO as it took down many well-known sites that were exposed to exploiting black-hat methods of gaining rank. It also allowed certain sites to climb the rankings that adapted the new practices fast.


Websites became more complex and interactive, presenting a challenge in terms of page speed, crawling, indexing, and rendering all of the elements.


Technical SEO came into its own as a direct response to this and allowed for a better way to approach SEO as a whole. We even have an SEO case study that shows how important technical SEO strategies work and grew keyword ranking by 961%.


Mobile-friendly design


Roughly 52% of global internet searches are made on mobile devices but this percentage varies from country to country. For example, 65% of searches are made on mobile devices in Asia according to SproutSocial.


For this reason, it’s certainly crucial that your website is mobile-friendly and that it performs properly on any device or screen size. This is known as ‘responsive’ web design.
