What Is Website Annotation?

What Is Website Annotation?

Readers often highlight texts, circle sections, or put comments in the margins of printed content like newspapers, study material, design blueprints, etc. However, that option is not available out of the box on websites.

To solve this issue, the Web Annotation Working Group of W3C has developed a Web Annotation Architecture.

Under the security guidelines of this group, software developers have come up with programs that can highlight, write, comment, crop, and do more on live websites. The website annotation does not make any changes to the actual website.

You can also share links to annotated web pages, collaborate virtually, discover web annotations, and store them for future use.

In a nutshell, webpage annotation brings a new layer of content creation, linking, and interactivity on top of a live website markup.    

Why Do You Need Website Annotation? 

Website annotation helps you to highlight content on a website and perform proofreading before the availability of webpage annotators; users need to take a printout of the website and write comments or highlight issues physically. Then they needed to scan the paper to send the annotation to the designer or developer.

Alternatively, users would take screenshots of a web page they need to annotate. Then, save the screenshot as an image on the Windows Paint app. And only afterward would adding texts, highlights, circles, comments, etc., be possible.

This prep work used to consume a lot of time. Project stakeholders, content creators, editors, designers, and developers were losing thousands of hours of productivity.

As soon as website annotation apps appeared in the market, users switched to such tools for annotating online resources. It saves time and makes the annotation work live, collaborative, and reproducible.
