Using Google Chrome DevTools To Improve Site Performance

Chrome DevTools is a set of web developer tools built directly into the Google Chrome browser. DevTools can help you edit pages on-the-fly and diagnose problems quickly, which ultimately helps you build better websites, faster. As a digital marketing agency, it’s essential to understand the backend of technology to be able to provide better solutions, faster.

And improved site performance is essential for any brand to have better visibility, and to prepare better inbound marketing strategies.

TWO IMPORTANT GOOGLE CHROME DEVTOOLS TO IMPROVE YOUR SITE PERFORMANCE ARE –

Performance Tool

Audit tool or Lighthouse

How can you access these tools?

Load your website in a Chrome browser

Right click on you webpage

Click on ‘inspect Element’

You will see different tabs – Elements, Console , Sources , Network, Performance, Memory, Application, Audits (recently named as Lighthouse) , Security

Here, we are going to discuss two tools which are on 5th and 8th tab from the left when we access the “inspect element” section of the webpage

Performance Tool:

To record Ctrl + E

To reload Ctrl+Shift+E  (to record page load)

Performance tool helps you to check load time of each element on your webpage. It helps to check runtime performance and load performance. Runtime performance is the performance of page when it is running and load performance refers to the performance of the page when it is loading. Both help to identify performance issues that affect speed and overall user experience.

This performance report shows frame by frame load time.

While running a performance tool, you will see load time taken by each element. You will encounter different terminologies on horizontal frames such as FP, FCP, LCP, FMP, DCL etc. Let’s have a look at each of these terms.

FP – First Paint

It is the time taken by first pixel when painted onto the webpage.

FCP – First Contentful Paint

It is a first content render on the webpage when user browses the website.

LCP – Largest Contentful Paint

It measures the loading performance of a website. LCP means time taken by largest element on the website to load. Ideal LCP score should not be more than 2.5 seconds.

FMP – First Meaningful Paint

As the name suggests, First Meaningful Paint means the time taken to provide the first meaningful information to users.

DCL – DOM Content Loaded

It measures when the HTML document on a webpage is loaded and parsed.

Audit or Lighthouse Tool:

An Audit tab gives you an overview of the metrics that improves performance, accessibility, SEO and other best practices areas.  It is also known as Google lighthouse report.

This is what the Lighthouse pane looks like (see below). You can check scores of the above-mentioned metrics for your website. They give scores for both the devices i.e. mobile as well as desktop. You can also check the performance score for the Progressive Web App if you have it.

To run this tool, you have to right click on the webpage you want to test. Then, click on “Inspect Element”. It opens up a pane where you will see this Lighthouse tab. After clicking on a “Generate Report”, it will provide a score as shown below –

With Lighthouse reports, you may get these recommendations that can help you to improve site speed –

A. Performance

Information regarding render-blocking resources

Server response time

Information about impact of third party codes on the website

Header information and server push

JavaScript execution time

Website cache policy

Number of requests to resources required to load the webpage i.e. request count

LCP (Large Contentful Paint elements) & CLS (Cumulative Layout Shifts on elements) issues. Read more about LCP & CLS issues here – https://support.google.com/webmasters/answer/9205520?hl=en

Information about minifying CSS & JavaScripts as well as HTML

Image Sizes and formats

DOM size

Network payloads

Unused codes like CSS and JS

Recommendations on animate content

B. Accessibility

Colours and contrast

Navigations

Names and labels for images, links and form elements

Meta viewport tag for mobile

Language attributes

C. Best Practices

Security aspects of JavaScript libraries used

Security in terms of HTTPS signals

Security aspects of cross-origin destinations

Copy-paste values into form fields

D. SEO

Image alt attributes

Tap sizes on mobile devices

Structured data

Meta viewport tags for mobile

Meta title and descriptions

HTTP response code

Status for robots.txt

Indexing status

Hreflang tags and canonical tags

Font sizes

Information about plugins

E. Progressive Web App

Page load information on mobile networks

Information about installability such as service worker and web app manifest

Redirections

Use of HTTPS

Cross-browser functionality

And other PWA optimisation aspects

Bonus: Alternative to Google Chrome Lighthouse tool is web.dev

Hope running these easy tests will help improve your site speed and performance. If you need any assistance to audit your website, contact Liqvd Asia tech and SEO support here!

How To Scrape & Automate Job Data From Websites?

In this article, we will scrape & automate job data from websites. Both of these tasks are achievable using several tools and libraries. Let’s have a look at each one of them.

Web Scraping: Web Scraping is a method that enables data extraction from websites and collecting them on spreadsheets or databases on a server. It is helpful for data analytics or developing bots for several purposes. Here, we will change it to small jobs scraper that can automatically run and fetch the data and help us see new scraped job offerings. The Job automate data scraper is the most used tool for this purpose.

Several different libraries help you achieve this task successfully:

Python: Both Scrapy and BeautifulSoup are the most popular used libraries for web scraping. The role of BeautifulSoup is to provide a simple interface for extracting data from HTML and XML documents. Scrapy, on the other hand, is a robust framework for building web spiders and crawling websites.

Node.js: Regarding web scraping in Node.js, Cheerio and Puppeteer are popular choices. Cheerio is a jQuery-like library that enables one to traverse and manipulate HTML. Puppeteer is a headless browser automation tool that is helpful for more complex scraping tasks.

Ruby: To perform web scraping in Ruby, Nokogiri is a commonly used library. It provides an easy-to-use interface for parsing HTML and XML documents and extracting data.

Android Automation: When it comes to performing automating tasks on Android devices, several tools and frameworks are helpful:

Puppeteer: a Node.js collection offers advanced API to switch Chromium over the DevTools Procedure. It possesses advance JavaScript and browser features.

Playwright: This library provides cross-browser automation via a single API.

Appium: Appium is an open-source tool for automating mobile apps on Android and iOS platforms. It supports multiple programming languages, including Java, Python, and Ruby, and allows you to write tests that interact with your Android app.

Thus, when it comes to scraping job websites, the best and most affordable option is to seek professional help from Job recruitment data scraping services. They are well equipped with the tricks and latest techniques that help obtain scraped job posting data and get the most relevant ones based on your needs.

Those, as mentioned earlier, are some of the few examples of the tools and frameworks required for web scraping job postings Python and Android automation. Depending upon your preference and specific requirements, you choose the one that best suits your requirements.

List of Data Fields

Job Title

Company name

Location

Job Summary

Description

Salary

Employee profiles

Job Postings

Company Profiles

Job Type

To scrape job recruitment data online, the site we are supposed to scrape is remoteok.io.

Installing Libraries: We use Puppeteer to scrape job data from the websites. To automate the scraping, we have to run the script every day. It is possible to use CronTab, a Linus time job scheduler utility. It is a headless browser API that offers the Chromium browser with easy control, similar to the other browsers.

We will use a framework generator to frame an project and the Pug template engine to show the scraped jobs via the Express server.

Inspecting the Site: The first and foremost step before scraping any site is to inspect every detail of the site content to know the process of building the script. However, scraping is a technique that mostly depends on understanding the website structure, like, how DOM is structured and which HTML Elements & attributes are important. We are using ChromeDev Tools or Mozilla Dev Tools for inspection.

Developing the Scraping Script

All async codes are handled using async/await. We will also export the primary function to the modules run to be used from outside and called from our server.

Next, we will look for the job and extract the Title, Company, and other details.

Lighthouse Bringing Better Recommendations to Google PageSpeed Insights

We all care about how fast our website loads.

At least, we should by now.

A fast website on any device or browser not only provides a better user experience but is rewarded by search engines with more authority, helping to improve your search rank.

If you really don’t know the importance of website load time, check out Christine and Marcus talk about it here, but before you do, let me tell you about this new update from Google that may give put it into perspective for you.

Drumroll.

PageSpeed Insight & Lighthouse Unite!

PSI now uses Lighthouse as its analysis engine.

Why is this a big deal? Well, as you may know, Google provides a variety of tools (like PSI and Lighthouse) to help you understand the performance of a single page or even your entire site.

While this is seemingly a good thing, recently, it was realized that having such a variety of tools caused some issues because they all had different recommendations, which could ultimately confuse the user.

Google decided to fix that and have PageSpeed Insights and Lighthouse (two long-offered tools) work together to bridge the gap.

PageSpeed Insight (PSI), for those of you not familiar with it, is a tool that analyzes the performance of a page on both desktop and mobile devices and provides you suggestions on how to improve your page.

Lighthouse, meanwhile, is an open-source, automated tool used for helping you improve your page. According to Google, it “gives you personalized advice on how to improve your website across performance, accessibility, PWA, SEO, and other best practices.”

Google states, by now working together, “... developers [will] get the same performance audits and recommendations everywhere: on the web, from the command line, and in Chrome DevTools.”

In other words, recommendations and data between the tools will now be consistent, reducing confusion and mixed messages.

What insights will users now get their hands on? Let’s start with each individual tool.

What Information Does PSI Provide?

With PageSpeed Insight, you are provided with the following information.

Lab Data. Using LightHouse, PSI simulates how a mobile device loads your page. Once completed, it summarizes the performance metrics, such as First Contentful Paint and Time to Interactive, and gives you a performance score from 0-100. Scores are categorized into three levels, a score of 90 or above is considered fast, and 50 to 90 is considered average, and below 50 is considered to be slow. …

Field Data. These are real-world performance metrics, First Contentful Paint and First Input Delay, for a page and its origin. The strengths of this report is it captures true real-world user experience and enables correlation to business key performance indicators. (Note that not all site may have field data available for display)

Opportunities. These are the suggestions that PSI provides on how to improve a page’s performance metrics and estimate how much faster the page will load, if you were to follow through with them.

Diagnostics. Provides additional information about how a page follows best practices for web development.

What Information Does Lighthouse Provide?

If you wanted to use Lighthouse as a solo website speed test, outside of PageSpeed Insights, the audit reports on a few key factors for each web page. They are:

Overall Performance. Included metrics are First Contentful Paint, First Meaningful Paint, Speed Index, First CPU Idle, Time to Interactive, Estimated Input Latency.

Progressive Web App. These checks validate the aspects of a Progressive Web App, as specified by the baseline PWA Checklist.

Best Practices. Some of these best practices include Uses HTTPS, Page has the HTML doctype, Avoids deprecated APIs, No browser errors logged to the console, etc.

Accessibility. These checks highlight opportunities to improve the accessibility of your web app. Only a subset of accessibility issues can be automatically detected so manual testing is also encouraged.

SEO. These checks ensure that your page is optimized for search engine results ranking. There are additional factors Lighthouse does not check that may affect your search ranking. Learn more.

Here is a guide that explains how Lighthouse calculates the scores.

In the Lighthouse report, audit has a reference doc explaining why the audit is important, as well as how to fix it.

What Does This Mean for You?

Your audits between all the different Google Performance tools will be less confusing and more cohesive!

As marketers, these types of tools you and your developers should truly care about as they help to make sure your site is optimal, and help improve your search engine ranking.

Whether you are making constant updates to your site or not, you should be checking on your performance to ensure you’re in-line with what search engines are looking for.

If PSI or Lighthouse tells you your site is running slow, and you want a few more recommendations, here are 5 ways you and your team can improve page load time on your website.

So, How Do I Get Started using Lighthouse or PSI?

You can run Lighthouse in ChromeDev Tools, and for more technical developers or marketers who like to tap into development, from the command line or a Node module.

Here you can find step by step directions for running Lighthouse.

For PSI, just go to https://developers.google.com/speed/pagespeed/insights/, enter your URL and hit the analyze button, to see your results.

Google Removes MetaMask from Chrome Extension Store

Google has abruptly removed MetaMask from the Chrome Extension store without any explanation. The Dapp browser extension has been unceremoniously removed from the Android and Chrome marketplace with no indication as to why, and if or when it will be restored.

MetaMask made the announcement on its Twitter handle on Wednesday July 25 in a tweet that read:

“PSA: MetaMask has been delisted from the Chrome Web Store. We are unsure of why this is the case and we will update everyone as we get more information. All other browsers are unaffected.”

Bad News For Ethereum Users

Currently, MetaMask plays an extrmely vital role in the mainstreaming of Ethereum, as it provides an interface between conventional web browsers and decentralised networks. Using MetaMask, users can access Ethereum DApps in their browsers with no need to run a full blockchain node.

Until Ethereum and other decentralized frameworks attain widespread adoption, such interfaces remain perhaps the most important part of the present Ethereum experience.

The sudden and unexplained delisting by the Google Chrome web store will make it more difficult for chrome users who do not already have the extension installed to access Ethereum Dapps, which could have a negative effect on the continued adoption of Ethereum.

For the time being other well known browsers than can run MetaMask, including Mozilla Firefox, Opera and Brave are not affected by the purge.

Speaking on Twitter, MetaMask expressed cautious optimism abut resolving the situation quickly, informing existing MetaMask users that the service should still work fine for the time being.

This would only affect new users on Chrome short-term as they would not be able to install it. Hopefully this resolves before we push up an update, which we would need a store listing (to our knowledge) to make happen.

— MetaMask (@metamask_io) July 25, 2018

As to whether this will continue going forward, there is still no indication yet, but MetaMask hopes that it will be able to reach out to Google and resolve the issue quickly.

While @googlechrome has taken MetaMask down from their @ChromeDev store without notice or explanation, users can still install MetaMask manually on Chrome by following this guide. Note: @brave, @firefox, and @opera stores are all working fine!https://t.co/11ElxRgjDL

— MetaMask (@metamask_io) July 25, 2018

In the meantime, MetaMask users have been taking to Twitter to voice their displeasure and speculations about the ongoing situation.

Some have speculated that the delisting is a simple mistake caused by an overzealous keyword function.

Chrome has banned crypto mining addons. They are probably using an automated system that banned Metamask based on keywords that are similar to those in mining addons.

— The Cryptophiliac (@thecryptophilia) July 25, 2018

Others have reacted with rage against Google, suggesting that the situation presents a perfect opportunity to migrate from Chrome to other browsers such as Brave.

Bye bye chrome, hello Brave. Bye bye google, hello Presearch. Bye bye instagram , hello Lit

— Ignasi Palazuelos (@IgnasiBCN) July 25, 2018

Amidst all this, both MetaMask and Augur have pointed out that fraudsters are looking to take advantage of the chaos by placing phishing apps on the Android store which impersonate MetaMask.

https://twitter.com/AugurProject/status/1022186967432192000

For now, no one can say for sure what the issue is, least of all MetaMask itself. Whether MetaMak is suffering a minor developer hiccup as speculated by some users, or it is the victim of a more permanent reorganization by Google remains to be seen.
