How to Configure Custom 404 Error Page

External developers can not configured 404 error page alone. Please ask dev support for help.

Step 1:

You need to extend the url configurations from the engine settings adding this: 

'urlconf': 'engine.{{roar_name}}.urls',

Step 2:

You need to add a urls.py file into this location: 

engine/{{roar_name}}/

with the url config for the 404 page, like the following: 

from rebelmouse import urls_roarhandler404 = urls_roar.handler404# handler500 = urls_roar.handler500urlpatterns = urls_roar.urlpatterns

Step 3:

You will also need a 404.html page that will act as the bootstrap html that will help you load the template. You can extend it from base_frontpage.html template.

The files should be located in: 

engine/{{roar_name}}/templates/community/roar

and it can contain anything, the recommended is to extend it like this: 

{% extends "community/roar/base_frontpage.html" %}

Step 4:

Create 404.xml file which will be your custom 404 file.

This file should be located in 

engine/{{roar_name}}/templates/dynamic_content/

Step 5:

To test it you can go to the 404 test page: 

http://example.com/404/page/not/found

You should see your 404 page.

Why Premium Creative Agencies and CTOs Choose to Develop on RebelMouse vs. WordPress and Drupal

The Intersection of Design and Development: Where Your Clients Thrive

We started RebelMouse seven years ago knowing that there was a fundamental design flaw in the world of traditional CMSs: Every instance, on every platform, had to be updated independently. It's similar to an era when users had to manage their own Microsoft Exchange Server for email. The costs of managing, maintaining, and iterating on a CMS to keep it awesome and world class is typically a $10 million-a-year endeavor. But even then, these cost-prohibitive CMSs are still behind the times.

Native Multivariate Testing at Scale With RebelMouse

What Differentiates Our Approach

There are many popular tools that allow you to perform experiments and A/B tests on your users — primarily Google Chrome Experiments and Optimizely. But all of these solutions are JavaScript additions to your web page that sidestep the problem of old, outdated, and clumsy CMSs. These solutions work by calling on a third-party JavaScript library that rewrites a page after it's rendered. This approach adds extra page weight and creates strange user experiences due to having to wait for everything to load and be rewritten on the fly.

At RebelMouse, we've solved this in a very elegant way. At the core level of our platform, we can natively render different layouts and track the exact differences in performance when comparing a test to your other layouts.

The RebelMouse Approach to SEO

An SEO Strategy That Wins With Every Publish

How exactly Google determines search ranking largely remains a mystery for publishers, but what we do know is that the search engine continuously rolls out updates to its algorithm. And while sometimes these updates are small and nearly unnoticeable, other times they result in massive changes around the way Google crawls content, often disrupting the rankings of webpages all across the globe.

With each one of these algorithm changes comes a new approach to search strategy. It's a lot to keep up with in a competitive digital landscape. Publishers are already burdened with the task of creating high-performing quality content that's easy to find on Google and, in turn, easily shared across social. It's a job that can't be solved with advertising dollars either. It's estimated that nearly 80% of users disregard paid search results. Pair this with the fact that 93% of all online experiences begin with a search query and you're left with the realization that it's never been more important to prioritize search engine optimization.

The good news is that RebelMouse has a unique approach to SEO that leverages the tools available to us from the open web alongside our proprietary technology that enables users to win key phrases with every publish. The best part? The platform is designed to empower the people who live closest to content: writers and editors. Here's how it works.

How to Monetize Your Website in Today’s Publishing Environment

In order to define distributive publishing, we have to ask the following question: If you have quality content, but nobody sees it, does it even exist? The answer is no, because your content needs to be supported in a way that lets it move seamlessly across all channels, especially site, search, and social. But let's take this question a step further: If you can't monetize your content to generate the support it needs, how do you create quality content in the first place?

Google’s Rich Results Test to Take Priority Over Structured Data Testing Tool

Google recently announced that its Rich Results Test is out of beta and now fully supports all of its rich results features.

Powered by structured data, rich results are the dynamic snippets you see at the top of Google's search results, whether it's a carousel, image, or listicle.

An example or Google's rich results for recipes.

The Rich Results Test determines if your website's structured data is set up correctly so that your page can be eligible for rich results. With this latest update, Google will be deprecating its Structured Data Testing Tool. Here are some reasons from Google about why the prioritization of their Rich Results Test is an upgrade:

RebelMouse Outperforms Every Other CMS. Here’s the Data to Prove It.

Our Core Web Vitals drastically outpace every competitor, and we have the receipts

In an effort to build user retention and increase conversions, publishers are making a common mistake. They're adding more features to their websites, including ad placements, but losing sight of the main revenue driver: user experience.

The key to unlocking user retention lies completely in site performance. Currently, publishers are trying to build optimized websites that translate easily across devices and platforms, but fail to deliver an experience that checks all their boxes and prioritizes their readers. It takes less than a second of delayed load time to turn away a user. This is why Google has made page speed a top ranking factor on search, and shepherded the entire open web's newfound prioritization on site performance.

Game Changer: Google's Core Web Vitals Announcement

Google cemented its seriousness about page experience with the announcement of its Core Web Vitals measurements in Google Search Console. Core Web Vitals are three specific metrics that Google uses to determine a site's overall usability. While these data points will evolve over time, the 2020 version of vitals consists of three specific metrics:

Largest Contentful Paint (LCP): A website's LCP is the time it takes to load the main content on a page. Google wants LCP to happen within 2.5 seconds of when a page first starts loading.

First Input Delay (FID): This metric quantifies a user's experience when trying to interact with unresponsive pages. This usually occurs between First Meaningful Paint (FMP) and Time to Interactive (TTI) (more on what these two mean below). You want your FID score to be low to prove the usability of your site. According to Google, pages should haven an FID of less than 100 milliseconds.

Cumulative Layout Shift Score (CLS): CLS determines how often your users experience unexpected layout shifts or changes on a page. To ensure visual stability, you want your CLS score to be low. Google wants pages to maintain a CLS score of less than 0.1.

From Google.

Google says Core Web Vitals scores will be considered across every page, and will be a ranking factor in its Top Stories feature. While relevant quality content will always be the most important, the page experience ranking is now a make-or-break metric for your site's survival.

"A good page experience doesn't override having great, relevant content. However, in cases where there are multiple pages that have similar content, page experience becomes much more important for visibility in Search." —From Google's page experience announcement, May 2020

Core Web Vitals will determine every site's performance score. You can see your site's Core Web Vitals specifically via Google Search Console, but your website's overall page performance is measured using Google's PageSpeed Insights and Lighthouse tools.

At RebelMouse, we guarantee a performance score of 90 or higher via PageSpeed Insights. To do this, we've built out a platform infrastructure that exceeds industry standards on Google's key metrics, particularly its Core Web Vitals, outperforming most industry leaders.

You can read more about how we've mastered Google's KPIs here. But the truth is in the data. Below is table that provides a snapshot into how RebelMouse-powered sites score:

And here's what the scores look like for some of the biggest sites on the open web:

As you can see, there's a lot of data Google takes into account even outside of Core Web Vitals. Here's a quick summary of the other important metrics that Google trusts to measure page performance:

First Contentful Paint (FCP): This metric measures the time from click to the time when a user's browser renders the first bit of content from the Document Object Model (DOM), which is your site's HTML structure. According to Google, this is an important milestone for your readers because it provides signals that your page is loading.

First Meaningful Paint (FMP): This is the amount of time it takes the most important content, what Google calls "hero elements," to load on site. Hero elements are different for every site, but should be intuitive based on your content. This metric helps determine your site's usability.

Time to Interactive (TTI): This is the most important metric to keep an eye on. This is when the site is fully rendered and ready for user action. This is a critical point when slow load time can occur, usually because JavaScript or other complex content hasn't fully rendered. So, in short, think of TTI as how long it takes for your site to load in its entirety.

Total Blocking Time (TBT): TBT measures a page's load responsiveness to quantify how long a page is non-interactive prior to becoming interactive. You want your site to have a low TBT to maintain its usability.

Speed Index (SI): SI is the measurement of how quickly the contents of a page are populated. You want your speed index score to be as low as possible.

Creating quality content is only half the battle in 2020, and publishers are already burdened with the around-the-clock task of creating content that resonates. This is why quality content must be supported by modern technology that can keep up with the speed of the web. RebelMouse provides publishers with a CMS that supports the new content lifecycle with an editorial suite designed for reach on site, search, and social.
