Rendering SEO Manifesto: Why We Need to Go Beyond JavaScript SEO

Going beyond JavaScript SEO is a must. Here’s how technical SEO pros can use their knowledge of batch-optimized rendering for better search visibility.

Want to make sure that your content gets properly accessed by search engines and ranks high?

In his SEJ eSummit session, Bartosz Góralewicz presented how Google is rendering websites on a large scale and shared insights based on Google’s patents and documentation.

Here’s a recap of his presentation.

The Problem with JavaScript

Góralewicz and his team found that 40% of content relying on JavaScript is not indexed after 14 days.

It gets worse.

Ten percent of URLs within an average domain are not indexed by Google and we’re talking unique indexable URLs.

This is something to look at, especially since these trends are changing over time and can get worse.

In 2015, Google claimed that they are good with rendering saying:

“[A]s long as you’re not blocking Googlebot from crawling your JavaScript or CSS files, we are generally able to render and understand your web pages like modern browsers.”

Since 2017, Góralewicz and his team have created a lot of other experiments, including cloaking experiments with JavaScript and others, that revealed crawling and indexing issues encountered by JavaScript-based websites.

That same year, Google started talking openly about JavaScript SEO.

Today, while we have Google’s Martin Splitt who has been incredibly helpful to the SEO community, there are still questions left unanswered.

In November 2019 at the Chrome Developer Summit, Splitt announced that the median for rendering at Google has improved from up to a week a year before to only five seconds in 2019.

However, Góralewicz and the Onely team’s additional research found that “the median rendering delay may be virtually non-existent for new websites, the delay in indexing JavaScript content is still very much there.”

Many JavaScript-powered websites don’t get indexed and don’t rank even after two weeks.

Understand the JavaScript SEO for Webmasters

Explore how Googlebot understands Javascript and how you can use Javascript SEO to keep your website visible and engaging for users.

JavaScript is an important part of the web platform because it provides many features that turn the web into a powerful application platform. Making your JavaScript-powered web applications discoverable via Google Search can help you find new users and re-engage existing users as they search for the content your web app provides. While Google Search runs JavaScript with an evergreen version of Chromium, there are a few things that you can optimize.

This guide describes how Google Search processes JavaScript and best practices for improving JavaScript web apps for Google Search.

This is a recording of the JavaScript SEO office-hours hangout from April 29, 2020. These sessions are open to anything around SEO for JavaScript sites

The Nuances of Constants in Go; Go Isn't JavaScript

Constants can be confusing and easy to misuse in Go if you are coming from an untyped language. Let’s take a look at some of the nuanced details of how they work in Go. It’s probably unsurprising, but Go’s constants are almost nothing like JavaScript’s bastardized version of the concept.

Go vs JavaScript

Many programming languages support constants, often denoted by the keyword const.

Go and JavaScript both declare new constants in the same way:

const frameRate = 60

Constants in Go

• Must be able to be assigned at compile time. The value of a const can’t be the result of a runtime calculation.
• Run faster because the compiler can make specific optimizations.
• Cannot change. The compiler will not allow them to be re-assigned.
• Only work with some types. Arrays, Slices, Maps, Structs, etc… can’t be made constant
• Are not normal Go types unless explicitly assigned as such
