There are several main ways to create websites - using ready-made CMS, creating through design services, developing from scratch and using frameworks. When it comes to CMS, SEO optimization is usually not particularly difficult, but for sites created manually or using Java Script frameworks, preliminary configuration is required for successful optimization.
Websites built using such technologies are called SPA (Single Page Application), which translated from English means “single page application”. This definition doesn’t mean much to people who are far from technology, so in this article we will take a closer look at the features of such sites, explain what the problems of SEO optimization are and how to solve these problems so that search engines can correctly index such pages.
The SPA site works in such a way that only one page is used for user interaction. Instead of loading a new page every time, the application dynamically updates only the necessary elements. This is done using JavaScript, which returns only the data required for replacement.
For example, when sorting products on a website, filters can instantly update results without reloading the page with new content.
This provides a number of advantages:
Popular frameworks for creating SPA websites include Angular, React and Vue.
Despite the obvious advantages, such sites also have their disadvantages, especially in the context of SEO. Search bots were originally designed to index individual pages. In the case of SPA sites, problems arise because most of the links on the site are not displayed in the source code, which limits the number of pages available for indexing.
Google began to effectively index SPA sites only a few years later, and Yandex may still have problems indexing such pages, which requires creating -versions of pages for each of them.
Despite the challenges, SEO for SPA sites is possible, and there are solutions that can handle these challenges. Here are a few approaches to help you set up proper indexing:
1. Using the parameter “?_escaped_fragment_=” (for Yandex). This method generates -copies of AJAX pages, available at separate addresses with the specified parameter. Detailed instructions can be found in the Yandex.Webmaster help.
2. Defining a search robot through a user-agent and providing copies of pages. For example, if AJAX pages use "#", you should replace it with "#!" so that search engines can index the content correctly.
For some frameworks there are ready-made solutions, for example, 5 mode for Angular. If the site uses traditional URLs, the task becomes easier - just serve a copy of the page.
3. Rendering copies on the server. In this case, pages are generated on the server and sent to search engines. However, this method requires additional resources to perform the operations.
4. Pre-rendering of static pages. Pages are rendered at deployment time, not while the server is running. After this, the created versions of the pages are saved on the hosting and sent to search engines. This avoids the need for a large amount of server capacity.
5. SEO-friendly URLs. Using hashtags when navigating through an SPA application is not recommended, as it interferes with search robots. It is now possible to use URL slugs, which simplifies indexing and follows best practices.
Also, don’t forget about setting up web analytics for SPA sites. To correctly track data and update counters, it is necessary to ensure that analytical systems are working correctly so that the data is updated when new page elements are loaded.
SPA sites provide an excellent user experience and are a good choice for creating high-load services. However, if you do not adapt them for SEO, you can significantly lose traffic, since search engines will not be able to fully index such pages.
However, with the application of these methods and solutions, these problems can be solved. Google has already learned how to correctly index SPA sites, and Yandex can be configured for effective indexing using -copies of pages. The main thing is to pay attention to setting up and adapting your site to the needs of search engines.
