Single Page Application & SEO


When people design a site, they make sure it contains eye-catching images and advanced features to make it look attractive. People also create their websites in a way that is user-friendly. SEO experts use different techniques to make the sites more interesting and appear in the top results of search engines.

However, some sites require SEO experts to put in a bit more effort to make them more interesting while working under the guidelines given by Google. These sites are comparatively difficult to manage as they are programmed differently, hence requiring complex SEO. These sites are known as Single Page App based on applications like AngularJS or ReactJS. Since it is time-consuming for Google and other search engines to index the pages on these sites, they become a nightmare for SEOs.

Single Page Application

Websites based on Single Page Application are one of the most complex sites you can ever go through as an SEO expert. These websites load a single HTML page and updates the page as visitors use the app. All the images, files, blogs, and external links are loaded when people are directed to the first page of the site. Advanced JavaScript templates are used by applications like AngularJS to run these Single Page App based sites.

Websites based on Single Page App (SPA) have their pros and cons far different from those of regular sites. Since all the content and all the pages of the site are loaded at once when the user logs on to the first page, a significant amount of time is required. Most people do not tend to wait much for sites to load and ultimately bounce off the site. The bright side of this fact is once the first page is fully loaded, navigating to other pages would be fast, allowing a much better user experience. As all the pages would already be loaded, you can easily navigate through the whole site without waiting for pages to load.

A major drawback of such sites cannot be ignored. The complex structure of these sites makes it difficult for search engines to index the site’s content, making SEO difficult and hence risking the ranking in the search results.

Problems with SAP Websites

Angular sites make SEO a major issue as crawling such websites does no good. There are various problems that web crawlers encounter while indexing these sites. What happens in most cases is that nothing except for JavaScript files/templates are detected. Most crawlers fail to detect images, all kinds of media files, keywords, texts and blogs in these sites. When these files are not found or detected, there is no way that search engines could determine the site’s rank in the search results.

Another problem in indexing these sites is what is known as a spider trap. Even if the content is detected somehow, there is a high chance you might be stuck in a spider trap. This is when the same content is indexed over and over again which is also gives the wrong signal of duplication to search engines.

Google and various search engines claimed they would encrypt these sites. They said they would come up with newer techniques to index all the pages and content of these sites. However, this is still not easily possible. SEO experts have come up with a never-ending list of problems that occur while indexing SPA sites. Some of these problems were also weird, as improper analytics data was indexed from some sites while some sites only allowed different and limited parts of the content to be indexed which was no better than indexing no content.

If you are facing the same problems while indexing SPA sites with JavaScript templates, worry no more as now there are a couple of ways and techniques that can help you overcome these issues. However, in order to carry out the problem-solving tasks, you need complete knowledge of SEO basics, JavaScript files, Angular sites and Single Page Applications.

How to Solve These Issues

Sites are indexed by various search engines, including Google and Bing, in order to determine the level of originality and authenticity that is then used to allocate a rank to your site. If you have a site, you would want it to appear on the first page of search results. To achieve a higher and noticeable rank, you would have to make the content of your site authentic, genuine, informative and interesting. Since search engines also consider the page speed of your site to determine its rank, it is important that you keep your site light and ultra fast.

Even if you own an Angular site, you would still have to make sure your site is fast, eye-catching and contains 100% original matter. You would be required to make a list of things on your site you want to be indexed. This can also include URLs, templates, back-links etc.

Once you have prepared a list, you should install Prerender. This software is a SEO lifesaver, as it would offer the crawlers a fully cached version of the site so that all the pages and content can be easily detected. Moreover, this software comes with some amazing options. If you do not want some pages of your Angular website to be indexed by Google or other search engines, you can easily “blacklist” them. Similarly, if you definitely want some pages to be indexed, you can “whitelist” them.

After you have installed the Prerender software, you need to check whether the “Prerendered” content is being indexed or not. You can check this by performing a manual site search using any search engine. This can also be done by using the Google Search Console.

If your site appears in the search results, you have successfully managed to overcome the major issue of SEO and Angular sites. If that is not the case, check where you might have made a mistake and correct it. You should make sure you track and monitor the site’s performance as new updates in Google algorithm might cause some changes. Keep your site updated, always!
