In this article, I will talk mainly about Vue.js, considering that it is the structure I have actually used most, and with which I have direct experiences in terms of indexing by the search engines on significant tasks, but I can assume that the majority of what I will cover stands for other structures, too.

Some Background On The Issue
How Indexing Functions
For your website to be indexed by Google, it requires to be crawled by Googlebot (an automatic indexing software that visits your website and conserves the contents of pages to its index) following links within each page. Googlebot likewise searches for unique Sitemap XML files in sites to discover pages that might not be linked properly from your public website and to get additional info on how frequently the pages in the site change and when they have actually last altered.
A Bit Of History
” Serving Googlebot various material than a typical user would see is thought about masking, and would protest our Webmaster Standards.”
Google (with its AJAX crawling plan) also guaranteed that you would avoid charges due to the truth that in this case you were serving different content to Googlebot and to the user. Nevertheless, given that 2015, Google has deprecated that practice with an official post that informed website managers the following:
How Does Google Actually Index Pages Produced With Front-End Frameworks?
In order to see what Google in fact indexes in sites that have been produced with a front-end structure, I developed a little experiment. It does not cover all usage cases, but it is at least a way to learn more about Google’s habits. I built a little website with Vue.js and had different parts of text rendered in a different way.
The website’s contents are drawn from the description of the book Infinite Jest by David Foster Wallace in the Infinite Jest Wiki( thanks men!). There are a number of initial texts for the whole book, and a list of characters with their specific bio:
- Some text in the static HTML, beyond the Vue.js primary container;-LRB- ***************************************)
- Some text is rendered immediately by Vue.js since it is contained in variables which are currently present in the application’s code: they are defined in the part’s
- #Some text is rendered by Vue.js from the
dataitem, but with a hold-up of 300 ms;-LRB- ***************************************)
- The character bios originate from a set of rest APIs, which I’ve built on purpose utilizing Sandbox Given that I was presuming that Google would execute the website’s code and stop after some time to take a photo of the current state of the page, I set each web service to react with an incremental delay, the very first with 0ms, the second with 300 ms, the 3rd with 600 ms and so on up to 2700 ms.
Each character bio is reduced and consists of a link to a sub-page, which is available only through Vue.js (URLs are created by Vue.js using the history API), however not server-side (if you call the URL of the page straight, you get no reaction from the server), to check if those got indexed too. I presumed that these would not get indexed, given that they are not appropriate links which render server-side, and there’s no other way that Google can direct users to those links straight. However I simply desired to examine.
I published this little test website to my Github Pages and requested indexing– take an appearance
The results of the experiment (worrying the homepage) are the following:
- The contents which are already in the static HTML content get indexed by Google (which is rather apparent);-LRB- ***************************************)
- The contents which are created by Vue in real-time constantly get indexed by Google;-LRB- ***************************************)
- The contents which are produced by Vue, however rendered after 300 ms get indexed as well;-LRB- ***************************************)
- The contents which originate from the web service, with some delay, might get indexed, but not constantly. I’ve checked Google’s indexing of the page in different minutes, and the content which was placed last (after a number of seconds) in some cases got indexed, often it didn’t. The material that gets rendered quite quickly does get indexed many of the time, even if it comes from an asynchronous call to an external web service. This depends on Google having a render budget plan for each page and website, which depends upon its internal algorithms, and it may vary wildly depending on the ranking of your website and the present state of Googlebot’s rendering queue. So you can not depend on content coming from external web services to get indexed;-LRB- ***************************************)
- The subpages (as they are not available as a direct link) do not get indexed as expected.
What does this experiment tell us? Essentially, that Google does index dynamically created material, even if originates from an external web service, but it is not guaranteed that material will be indexed if it “shows up too late”. I have had similar experiences with other genuine, production websites besides this experiment.
Okay, so the content gets indexed, however what this experiment does not inform us is: will the content be ranked competitively? Will Google choose a site with fixed material to a dynamically-generated site? This is not an easy question to respond to.
From my experience, I can inform that dynamically-generated content can rank in the leading positions of the SERPS. I have actually worked on the website for a brand-new model of a significant vehicle company, releasing a new site with a new third-level domain. The website was fully created with Vue.js– with really little content in the static HTML besides
The site started ranking for minor searches in the first couple of days after publication, and the text snippets in the SERPs reported words coming straight from the dynamic material.
Within 3 months it was ranking initially for many searches connected to that vehicle model– which was fairly simple given that it was hosted on a main domain coming from the cars and truck’s maker, and the domain was greatly linked from trusted sites.
However given the reality that we had actually had to face strong opposition from the SEO business that supervised of the task, I think that the outcome was still impressive.
Due to the tight due dates and absence of time provided for the task, we were going to release the site without pre-rendering.
What Google does not index is heavily-animated text. The website of among the business I work with, Rabbit Hole Consulting, consists of great deals of text animations, which are performed while the user scrolls, and need the text to be split into numerous chunks across different tags.
The main texts in the website’s web page are not suggested for search engine indexing given that they are not optimized for SEO. They are not made of tech-speak and do not utilize keywords: they are only suggested to accompany the user on a conceptual journey about the company. The text gets inserted dynamically when the user goes into the different areas of the home page.
None of the texts in these areas of the site gets indexed by Google. In order to get Google to show something significant in the SERPs, we included some static text in the footer listed below the contact kind, and this content does show as part of the page’s content in SERPs.
The text in the footer gets indexed and shown in SERPs, although it is not immediately noticeable to the users unless they scroll to the bottom of the page and click the “Concerns” button to open the contact form. This verifies my opinion that content does get indexed even if it is disappointed instantly to the user, as long as it is rendered quickly to the HTML– rather than being rendered on-demand or after a long delay.
What About Pre-Rendering?
So, why all the difficulty about pre-rendering– be it done server-side or at project compilation time? Is it truly required? Although some structures, like Nuxt, make it a lot easier to carry out, it is still no picnic, so the option whether to set it up or not is not a light one.
I think it is not mandatory It is certainly a requirement if a lot of the content you want to get indexed by Google originates from external web service and is not instantly readily available at rendering time, and might– in some unfortunate cases– not be readily available at all due to, for instance, web service downtime. If throughout Googlebot’s check outs some of your material shows up too gradually, then it might not be indexed If Googlebot indexes your page precisely at a minute in which you are performing upkeep on your web services, it may not index any vibrant content at all.
Moreover, I have no evidence of ranking differences between static material and dynamically-generated material. That may require another experiment. I believe that it is extremely likely that, if content comes from external web service and does not load right away, it may effect on Google’s understanding of your website’s performance, which is an extremely important factor for ranking.

Other Factors To Consider
Google has actually recently announced that it is now running the most recent variation of Chromium (74, at the time of composing) in Googlebot, and that the variation will be updated frequently. The reality that Google was running Chromium 41 may have had huge implications for sites which decided to ignore compatibility with IE11 and other old browsers.
You can see a contrast of Chromium 41 and Chromium 74’s support for features here, nevertheless, if your site was currently polyfilling missing features to stay compatible with older web browsers, there ought to have been no problem.
Constantly use polyfills since you never know which internet browser misses out on support for functions that you believe are commonplace. For instance, Safari did not support a significant and extremely beneficial new feature like IntersectionObserver up until variation 12.1, which came out in March 2019
Other Online Search Engine
The other online search engine do not work in addition to Google with dynamic content. Bing does not seem to index dynamic material at all, nor do DuckDuckGo or Baidu. Most likely those search engines do not have the resources and computing power that Google has in spades.
Note: To get more info on other search engines’ rendering capabilities, you can examine this short article by Bartosz Góralewicz. It is a bit old, however according to my experience, it is still legitimate.
Keep in mind that your site will be visited by other bots as well. The most essential examples are Twitter, Facebook, and other social networks bots that require to bring meta info about your pages in order to show a preview of your page when it is connected by their users. These bots will not index vibrant content, and will only show the meta details that they discover in the fixed HTML. This leads us to the next consideration.
title tag and meta description/information.
The conclusions I’ve concerned while investigating this post are the following:
- If you just target Google, it is not necessary to use pre-rendering to have your site completely indexed, however:
- You ought to not depend on third-party web services for material that requires to be indexed, especially if they do not reply quickly.
- The material you insert into your HTML instantly through Vue.js rendering does get indexed, but you shouldn’t use animated text or text that gets placed in the DOM after user actions like scrolling, etc.
- If your website has several pages, you still require to have some logic to develop pages that, while depending on the exact same front-end rendering system as the web page, can be indexed by Google as individual URLs.
- If you need to have different description and sneak peek images for social media between different pages, you will require to resolve this too, either server-side or by putting together fixed pages for each URL.
- If you require your website to perform on online search engine other than Google, you will definitely require pre-rendering of some sort.
