6 elements to validate on the website before going online. [developer and website owner guide]

If you are a business owner, you have to agree with me that it is sometimes difficult to validate the quality of a website. In this article, I give you some elements that can help you in this direction. Applying these tips does not necessarily require technical skills.

As a business owner, it is sometimes complicated to validate a website. This is because, for the most part, people trust what they see (i.e. design). Sometimes, if they can access their site through their computer or tablet, they validate that everything is perfect. However, an invalidated website sometimes has 3 big risks: the possibility of being hacked shortly, reduced performance and difficulty reaching its target. Today, I will give you tips that will allow you to validate your website. Rest assured, you don’t have to be a developer to do this.

Validation of a site’s performance

Several online tools can help you validate your website’s performance. We can cite, among others: GTmetrix, Pingdom, or Google Page Speed insight. Each of these tools has the same point in common, i.e. tell you how fast your site is accessible on different types of screens. The principle of use is the same, namely:

  • Visit the site,
  • Add your URL,
  • Click on the analysis button,
  • Wait a few seconds, and you will see a performance report.

Example of using GTmetrix to validate a website

GTmetrix is an online tool that you can use for free to validate performance. With GTmetrix, for example, you can get an idea of how long your site takes to run, compare performance by region, or assess what is slowing down your site. With a free account, you can rate performance based on cities or countries. Just because your site is fast on your devices doesn’t mean it will be fast on your users’. As a Business Owner, you finally have the necessary data to validate the work of your developer.

To use GTmetrix, you must

  • Visit the GTmetrix.com website.
  • On the home page, enter your page to analyze in the form: for example, https://www.prositeweb.ca/a-propos/.
  • Once this is done, click on “Test Your Site.”

After about a minute, you will see a report appearing on your site’s performance. You also have the option of downloading this report in PDF format.


HTML syntax validation- W3C Validator

The world of the web is changing, and the codes too. Having said that, some syntaxes are no longer supposed to be used in the web development process. Or, there are rules or standards proposed by W3C which are strongly recommended. So, if in the process of developing your site, you use obsolete syntaxes or do not respect W3C standards, you may have 3 problems:

  • A reduction in the execution time of your site.
  • Security risks.
  • A higher bounce rate – which is the consequence of the reduced page load time.

About W3C

W3C is an organization that defines standards on the web. He made available to developers a platform called W3C Validator, which validates HTML syntaxes. You can therefore use it to check if your site is using the updated tags. You also can see through the results if certain tags are not affecting your site’s performance.

How to use the W3C site to validate a website?

Using W3C is simple:

After a few minutes, you will have a report on the page you have analyzed.

Validation of SEO errors

Nowadays, a website alone is not enough to position yourself on the web. It will certainly take time to be visible on the search engines. However, if you don’t take the time to validate that everything is in place to speed up the SEO process, you will risk getting frustrated in the short term. Here, we offer you some elements to consider, namely, the important tags for better positioning, the meta elements, your site’s performance, and other aspects.

For this, you can use the platform https://www.prositeweb.ca/seo/. The principle is similar to the other two cases (GTmetrix and W3C); namely: enter its URL, click on the button “analysis,” and get the results.

Analyse SEO

Use pro-sitemaps to detect error pages.

Usually, with website development tools such as WordPress, Magento …, your developer may need to use a theme or create test pages. Once development is complete, to ensure that these pages are deleted, you can generate a sitemap and analyze it. The sitemap usually gives you a list of all the pages on your website. So if you take the time to go through it, you may find that there are pages that are not supposed to be there. An example of a tool that I can recommend to you to produce your sitemap is https://pro-sitemaps.com. With Pro Sitemaps, in addition to the XML file of your sitemap, you will have a list of non-existent pages.

Activate the display of errors on the site locally.

Before deploying your website, you can use your server functionality to activate and view backend development errors. Several web servers provide the ability to display errors, which can help fix hidden bugs and validate code quality.

Confirmation of compatibility with browsers.

The site’s compatibility with browsers is another important aspect that should not be overlooked. Indeed, it is almost impossible to predict which browser a potential customer is using. Sometimes, even if its browser is validated, the version may not be compatible with your site. Validating a website’s compatibility with browsers can help to:

  • Make sure that the site is functional on the most popular browsers.
  • Check if the performance does not change depending on the browser.
  • Fix any possible compatibility issue.

Below are some tools that can help in this direction:

  • Add your URL,
  • Validate permissions,

Once your site is analyzed, you will have a security report in PDF format. The screenshot below is an example of a scan result.
