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

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 three significant 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 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. You can rate performance based on cities or countries with a free account. 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 your developer’s work.

To use GTmetrix, you must

  • Visit the GTmetrix.com website.
  • On the home page, enter your page to analyze in the form: for example,
  • Once this is done, click on “Test Your Site.”

After about a minute, you will see a report 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. Some syntaxes are no longer supposed to be used in web development. 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 three problems:

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

About W3C

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

How to use the W3C site to validate a website?

Using W3C is simple:

  • Visit the site W3c.
  • Enter your URL in the form,
  • Click on Check,

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 undoubtedly 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: the essential tags for better positioning, the meta elements, your site’s performance, and other aspects.

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

Use pro-sitemaps to detect error pages.

Usually, with website development tools such as WordPress and Magento …, your developer may need to use a theme or create test pages. Once development is complete, you can generate a sitemap and analyze it to ensure that these pages are deleted. The sitemap typically 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 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 crucial 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:

  • First, ensure the site is functional on the most popular browsers.
  • Check if the performance does not change depending on the browser.
  • Finally, fix any possible compatibility issues.

Below are some tools that can help in this direction:

  • Create your account,
  • Add your URL,
  • Validate permissions,
  • Start the site analysis.

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