Add Schema.org JSON-LD Microdata for SEO (Homepage)

[RiccardoMasutti]

We should add schema.org microdata to Bisq website for a better Search Engine Optimization as specified on https://schema.org/SoftwareApplication and https://developers.google.com/search/docs/data-types/software-app?hl=en.

Example of a Rich Snippet inside Google's SERP (search engine result page):

What is Microdata?

Microdata (like RDFa and Microformats) is a form of semantic mark-up designed to describe elements on a web page e.g. review, person, event etc. This mark-up can be combined with typical HTML properties to dedlfine each item type through the use of associated attributes. For example, ‘Person’ has the properties name, url and title – attributes can be applied to HTML tags to describe each property.

What is Schema.org?

Schema.org is a universally supported vocabulary extension by Google, Microsoft and Yahoo! for mark-up languages such as Microdata. It is designed to make the lives of webmasters easier, by offering one standardised mark-up understood by all the major search engines. Currently, Schema.org is compatible with Microdata, RDFa and JSON-LD.

What is JSON-LD?

Based on the popular JSON format, the linked data format JSON-LD allows webmasters to define the context of the data contained through the use of types and properties. When combined with Schema.org, these properties follow a standardised mark-up supported by major search engines, and joins Microdata & RDFa as methods for integration. Unlike Microdata & RDFa, JSON-LD offers greater ease of implementation with all the necessary mark-up contained within inline <script> tags, instead of wrapping HTML properties. However, as elegant and lightweight that JSON-LD is, there are some potential road blocks. In some instances it’s just not practical to mark-up content, for example that on a larger scale, as the content would need to be effectively repeated within the script tags in order to validate. Also as the mark-up is invisible, the likelihood of marking up content that is not on the visible page increases, which is against search engine usage guidelines. It is for these reasons that Google in particular still favours Microdata & RDFa for marking up HTML content.

Why use markups on Bisq website?

Marking up content on Bisq website can:

• Lead to the generation of rich snippets in search engine results like the one showed on top
• Enhance CTR (Click Through Rate) from the search result
• Provide greater information to search engines to improve their understanding of the content on Bisq website

Thanks for this—seems like low-hanging fruit to improve site traffic and perhaps downloads.

Some of my comments might be subjective, but I would say that such unclear things are better left unspecified/omitted.

@RiccardoMasutti some final feedback. Mostly little things, along with a couple of questions that could use your advice/guidance.

Sorry, one more thing. I just realized when merging #307 that this PR would cause post pages to have 2 conflicting JSON-LD specifications since post pages also use the default.html layout.

My suggested changes here skip adding JSON-LD markup to default.html when the page is for a post. This should fix the issue.

It looks to me like the changes in this PR should not conflict with the FAQ markup from #291, but let me know if you think otherwise.
