Site performance and speed

Among the 10 points that Google prioritizes, the speed and performance of sites are a key element. Search engines tend to favour sites that respond quickly to the user. In other words, does your site provide timely information that a prospect is looking for?

Whatever technology or CMS supports your website, simple and effective optimizations can be implemented quickly to speed up your site’s performance for the user and Google.

Why work the performance of your website?

Of all the websites on Google, many have lower performance. With low performance, it will be very complex and difficult to please search engines and users, and to get good results on search engines. For example, nearly 40 people leave a website when it takes more than 3 seconds to load. The speed of the site is an essential criterion for good performance in the eyes of Google.

In order to put all the chances on your side, you need to work on the performance of your website before putting time and energy into your organic referencing and strategy. If your website is underperforming, you won’t get the results you want. On the contrary, with a high-performance website, you promote your chances of reaching better positions on search engines. To do this, BlackCatSEO applies effective optimizations to improve the performance of your website, including:

  • Corrections in the code
  • Cache optimizations
  • Corrections in the CSS
  • Corrections in Javascripts

Check out some of the improvements we’re making:


Sometimes simple code errors slow down your site’s performance and penalize it. We specialize in researching and correcting common problems related to the development of your site, such as:


  • HTML/Php/etc errors
  • Canonicalization errors
  • Pagination for the crawler
  • Server errors
  • Duplicated and similar content

An excellent knowledge of current CMS and web technologies allows us to identify the most important fixes, and to correct them in a minimum of development time. Using several unique software, we map the issues with several paths to achieve the results you have set for yourself.

In some cases, ‘on-the-spot’ correction of common errors is a good option: it allows for rapid, and lower-cost, improvement in organic results over the medium term. Sometimes a complete change of CMS is recommended in order to optimize seOment over the long term, without subsequent constraints. Our proposals are clear, and the choices are yours!

Cache optimization

Several items on your website can be stored so that subsequent visits from your customers are faster. . Most web pages include resources that rarely change, such as CSS files, image files, javascript files…. These resources take time to download, while the HTTP cache allows these resources to be saved – or ‘hidden’ – by a browser or proxy. Once the resource is ‘hidden’, the browser can refer to the copied local resource rather than having to download it again. By phasing out these http queries, it’s possible to dramatically reduce the average loading time on your web page.

The various style elements (CSS), for example, can benefit from compressions, bundling, or outsourcing, whether you’re working on WordPress, Joomla or any other CMS. By correcting certain practices, such as the use of CSS @import,performance scores increase significantly, and allow to go back in the rankings. Google recommends a maximum of three style sheets. Some sites sometimes accumulate dozens of CSS files that can be aggregated and outsourced to reduce the site’s loading time.


It is common to find Javascripts directly injected into the source code of your site, or whose order is not optimal. Also, several javascript files are separate so they could be grouped and outsourced to further reduce your page’s loading time. An optimal partition allows you to group many files into one, or a few, and reduce your site’s loading time by three.

Our priority is to provide you with a high-performance technical base, capable of supporting well-defined content, an increase in crawls and visits, as well as any subsequent strategic improvements.
