Quick Guide on Google Webmaster Guidelines: Blocking CSS and Javascript

We are all aware that Google is very strict about the guidelines and I strongly believe whether you are a beginner or expert, make a habit of following guidelines. It always helps to get the best result out of your effort.

Many times you might have realised that even after putting a lot of effort you are not getting the satisfactory result. WHY?

Because somehow we must have avoided some Google Webmaster guidelines. It’s not new what I am sharing here but I am trying to brush up some old and very important update announced by Google about the Webmaster Guidelines.

Google Webmaster Guideline Update:

Blocking CSS or JavaScript files from GoogleBot may leave a negative impact on indexing and search result.

According to Pierre Far, Webmaster Trend Analyst “For optimal rendering and indexing, our new guideline specifies that you should allow Googlebot access to the JavaScript, CSS, and image files that your pages use. This provides you optimal rendering and indexing for your site” Disallowing crawler directly harm Google’s algorithm.

After this update, the main question was how can we ensure that GoogleBot is rendering the CSS and JavaScript files. Then Google came up with the solution as fetch and render tool within the webmaster dashboard.

I have realised over the period of time whenever people try to be smart, Google proves that they are smarter. 🙂

Let me give you a bit closer tour:

I will not make it techie. Let’s keep it simple. When ‘fetch and render’ were not in the picture GoogleBot use to see webpage like below:


So basically, this update helped GoogleBot to understand webpage layout more closely. This has helped a lot to the website which has graphics, Ads etc.

Example: If there is a product based company who is running Ads on the webpage and GoogleBot is not able to access CSS and JavaScript files, it cannot see where the Ads are on the page.
