Source Code

Source code is a computer program or webpage which is converted into a language that is read by a machine and compiled in image and function. Source code is an important part of SEO because it determines the correct execution of a webpage. Source code optimization is therefore part of technical SEO.

Source code for web pages[edit]

While the source code is the backbone of a computer program for programmers, it is an important area for online marketers which is not visible to regular users. SEO errors can be detected and fixed in the source code and it also contains important additional information about a website. By analyzing the source code, you can, for example, track down hidden links. Moreover, the source code contains important information about the CMS being used, markup or meta data in the Dublin Core.

Relevance to SEO[edit]

Correct execution of the source code of a web page can be counted among the ranking factors of search engines like Google. A defective source code can result in reduced functionality of a website and therefore a downgrade in ranking. The text-to-code ratio is also useful for on-page optimization.

Source code optimization is also important to reduce the loading time of a website. Since the loading time is regarded as a ranking factor, the optimization of the source code is necessary for this reason. A lean source code also enables crawlers to find and index content more quickly. Thus, they require less time to crawl a single page and therefore crawl depth can be increased.
