JSON-LD explained for personal websites

mananaysiempre

A bit disappointing that (IIUC) for the common parsers you have to say everything twice, in HTML and in the accompanying JSON-LD form even though RDFa exists for the exact purpose of letting you point at the values already present in your markup. (Admittedly RDFa is perhaps too flexible for its own good when you just want to mark up some stuff, but if you’re writing a full parser anyway dealing with a bit of excessive cleverness in the format should not be too bad.)

We have semantic HTML, but for some weird reason we need to yet again re-express the semantic meaning of our website in bespoke weird JSON in a script tag that the browser won't process.

Super useful article, wish that had existed in my seo days. I had misunderstood the type field, because to me I was often just linking to a webpage, even if it is for a saas, the marketing page is still a webpage.

I would encourage people who have the pragmatic bent to read about JSON-LD from the Google documentation for web sites; https://developers.google.com/search/docs/appearance/structu... You’ll also notice that a lot of the information is relevant to only a small subset of sites. Rotten Tomatoes can publish the critic rating for movies using JSON-LD, but that’s not relevant for me (even if I write a review for a movie). JSON-LD is nice because it’s easy and it is actually used by search engines. Yes, it can duplicate information in the web page itself, but I think the dream of perfectly annotating information so it only appears exactly once in your document is, well, a dream of spherical cows and massless ropes. It takes human effort to make a webpage and I am ok with a little duplication in the final product. My <h1> duplicates information in <title> anyway.

> It can aid web crawlers in understanding the semantic structure of your site, qualifying you for richer link previews, and even potentially improving your search ranking. This is fighting the last war, to stretch a metaphor. As far as I and my WWW site are concerned, Google has nowadays switched to giving people lengthy LLM-generated versions of my stuff, with errors, above pointing people to my actual stuff. 'Breadcrumbs' and getting a pretty display name instead of the domain name, don't address the fact that Google de-prioritizes all of that, pretty tweaks or no, nowadays. This is a lot of effort for stuff that people visiting my actual site directly will never see, and which people using Google will not find above the fold of its own massively LLM-ized version of stuff.

Do these attributes actually help with search engine visibility or do they just make it easier for search engines to keep users from leaving the search page? Honest question here.

Imagine if we had managed to deliver on the original promises of the Semantic Web, instead of having these locked-in platforms. How incredibly useful all that linked and structured data would've been to humans and LLMs at the same time. https://www.w3.org/2001/sw/

It seems useful but then we have to manage similar metadata in multiple places, so hygiene around consistency becomes important

If only there was some kind of markup language for websites where different tags could have different meanings. If only.

Some additional information, what you actually want to implement for every website is Structured Data, using the Schema.org vocabulary. JSON-LD is one of the ways to do this. There's also RDFa and Microdata. I used this article and can recommend it when I first learned about it: https://neilpatel.com/blog/get-started-using-schema/ You can try exploring what data to add with this tool: https://technicalseo.com/tools/schema-markup-generator/ The full list can be found on the schema.org site: https://schema.org/docs/schemas.html

In the old days (a few weeks ago) you could read google’s SEO recommendations and guidelines. This was great for debunking many a recommendation from clueless SEO agencies trying to force requirements on dev teams. Is there any similar recommendations available for their new, LLM, world?

Reinventing XML but worse.

There is a fine balance after which the symbiosis turns into exploitation. Websites trying to get visibility with the help of search engines was mutually beneficial to a large degree. However this is altogether going in a direction where the website owner is getting nothing for their sweat work.

For rich link previews, OpenGraph[0] is much more often supported than JSON-LD. For seo purpose, the kind of JSON-LD a search engine will support is very specific and limited. You are far better consulting the targetted search engine's documentation (Google[1], Bing[2]) and following that. Anything else is a waste of time. Outside of search engines, again, without a specific purpose, JSON-LD is mostly useless. If you have a specific need that requires JSON-LD, go ahead and include the data you know will be useful. Including anything else is like shouting into the void. IndieWeb[3] does use structured data but considers JSON-LD a DRY violation and uses Microformats[4] instead. 0: https://ogp.me 1: https://developers.google.com/search/docs/appearance/structu... 2: https://www.bing.com/webmasters/help/marking-up-your-site-wi... 3: https://indieweb.org/ 4: https://microformats.org/
