2 – Validation of HTML- W3C Validator syntaxes

The web world is changing; and the codes too. That said, there are syntaxes that are only supposed to be used in the web development process. Or, there are rules or standards proposed by W3C which are strongly recommended for better performance. Thus, if in the development process of your site, you use obsolete syntaxes or do not respect W3C standards, you may have 3 problems:

  • First, a reduction in the execution time of your site.
  • Second, security risks.
  • A higher bounce rate – which is the consequence of reduced page load times.

About W3C

W3C is an organization that defines standards on the web. It has made available to developers a platform called W3C Validator which allows HTML syntaxes to be validated. You can therefore use it to check if your site is using up-to-date tags. You also have the possibility to see via the results if certain tags do not affect the performance of your site.

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

Use our SEO analyzer

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

Use pro-sitemaps to detect error pages

Generally with website development tools such as WordPress, Magento …, your developer may need to use a theme or create test pages. Once the development is complete, to ensure that these pages are removed, 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 realize that there are pages that are not supposed to be there. An example of a tool I can recommend for producing your sitemap is Pro-Sitemaps. With Pro Sitemaps, in addition to the XML file of your sitemap, you will have the list of non-existent pages.

Enable locally the display of errors on the site (During development)

Before your website is deployed, you can use your server functionality to enable and view backend development errors. Many web servers provide the ability to display errors and this can help fix hidden bugs and validate code quality. If you use a content manager such as WordPress, you can change the value of the WP_DEBUG constant to true.

4- Validation of compatibility with browsers.

The compatibility of the site 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 the browser is validated, the version may not be compatible with your site. Validating a website’s compatibility with browsers can help:

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