View Rendered Source
View source is dead. See how the browser renders a page, not just what the server sends. A lightweight Chrome Extension that shows you how the browser has constructed (rendered) a page's original HTML into a functioning DOM, including modifications made by JavaScript. An essential tool for web developers using JavaScript frameworks like Angular, ReactJS and Vue.js, and for SEOs to understand how search engines see your pages, especially considering Google's dynamic serving workaround. Differences between raw and rendered versions are highlighted line-by-line showing how JavaScript has modified a page at render time. * Raw: The source code sent from the server to the browser before the DOM is rendered. The same as you'll see with traditional 'View Source' in the browser (after minor formatting tweaks) * Rendered: The rendered page after the source has been interpreted into a DOM, including any modifications made by Javascript * Difference: The difference between the rendered source and the raw source. Differences occur when JavaScript has modified the DOM. Adaptive website? If you serve different source code to mobile devices, emulate this easily with a mobile user-agent checkbox. Dynamic serving for Google? (More info: https://developers.google.com/search/docs/guides/dynamic-rendering) Using Google's dynamic rendering workaround designed for Javascript-heavy sites? Just request the raw source as Googlebot and ensure perfect technical SEO. Works with GatsbyJS and Prerender. DM the developer: https://twitter.com/ItsHogg
OpenLink Structured Data Sniffer
What is it? The OpenLink Structured Data Sniffer (OSDS) is an extension for Web Extensions compliant browsers (e.g., Google Chrome, Microsoft Edge, Opera, and many others) that discovers Metadata embedded within HTML documents as Structured Data Islands and presents what's discovered using a Property Sheet presentation style. Currently, OSDS supports discovery and processing of Structured Data Islands published using notations such as Microdata, RDFa, JSON-LD, RDF-Turtle, RDF-XML, CSV, and JSON. Why is it important? It simplifies the process of understanding what a given HTML document is about, via its metadata, for both end-users and developers. For instance, it helps Digital Brand Managers, Digital Content Managers, and Semantic Search Engine Optimization (SSEO) practitioners understand what may or may not be affecting Search Engine Results Pages (SERPs) placements. Simply install the extension to your browser and then visit a page of interest. On page arrival, the OSDS icon will be visually activated thereby indicating metadata discovery; once the icon is clicked, you will be presented with a presentation of transformed metadata.
