My experience with Facebook made me doubt that computers are deterministic machines 🙂 Sometimes it will accept image of any size (between 200 and 1500px), sometimes complain that image is too small (og:image should be larger) even if image is squared and bigger than minimum size (e.g. 400x400px). I had situations where the same link … Read more
Don’t forget that they also want you to declare some schemas to the html tag – specifically the open graph one via xmlns:og=”http://opengraphprotocol.org/schema/. OG is based on RDFa which adds the additional attributes to the meta tags. Once you’re done with that, be sure to add your fb:like – <fb:like href=”http://developers.facebook.com/” width=”450″ height=”80″/> – the … Read more
The image is appearing in the Facebook debugger (although it doesn’t look great since you’ve got some transparency which works best with your grey background which FB won’t take) Also its best to use a square image. One thing I’ve found it that Facebook caches the meta data on their side. So if we do … Read more
Are those tags on ‘http://www.mywebaddress.com’? Bear in mind the linter will follow the og:url tag as this tag should point to the canonical URL of the piece of content – so if you have a page, e.g. ‘http://mywebaddress.com/article1’ with an og:url tag pointing to ‘http://mywebaddress.com’, Facebook will go there and read the tags there also. … Read more

So facebook is changing its policies so that the personal … Read more
The Facebook API limit isn’t really documented, but apparently it’s something like: 600 calls per 600 seconds, per token & per IP. As the site is restricted, quoting the relevant part: After some testing and discussion with the Facebook platform team, there is no official limit I’m aware of or can find in the documentation. … Read more
og:url basically tells the FB scraper “ignore anything on this page, and scrape this url instead” So it’s doing exactly what it’s supposed to do. If you want the like button to point to a different url, use the href parameter and have it point to a different url. See https://developers.facebook.com/docs/reference/plugins/like/ for more information.
Have a look at the Facebook developers page: https://developers.facebook.com/docs/reference/opengraph/object-type/article It looks like your examples 2 and 3 have incorrect formatting. None of the “article” properties should begin with “og:” Here’s what I have on one of my sites, and I get no errors from the FB debugger: <meta property=’og:type’ content=”article” /> <meta property=’article:author’ content=”https://www.facebook.com/YOUR-NAME” /> … Read more
I was curious, so I scoured around trying to find an answer to the “default image” question. This was literally the only link I could find where any research had been done on the matter, where they suggest that higher-res images will receive top priority: How to set priority order to Open Graph images for … Read more
There isn’t a hard limit on the data you can put there, but in various rendering places Facebook will limit it. The limit in news feed is different from the limit in Ticker which is different than the limit on timeline. Just put the correct content in there and we’ll truncate it when rendering.
