Hi !
I started recently playing with the Onebox gem to see why it wouldn’t Onebox my site: [https://www.avito.ma](https://www.avito.ma).
I am no ruby developer but I understood that based on the URI , Onebox chooses what engine to use.
I also believe that there is an engine called html which is the default one if the link doesn’t match any predefined engine.
The question I’m asking is : why doesn’t onebox choose the default engine HTML to my website? When I’m debugging the @engine\_class I get nil in the preview class , initialize method.
All answers are much appreciated.
Thanks you

Did you try checking your site in [Iframely URL Debugger - Open Graph, Twitter Cards, oEmbed](http://iframely.com/debug) first?

Not sure, perhaps @zogstrip can advise.

Open Graph [has **4** required fields](http://ogp.me/) (title, type, image and url). Your website only shows `title` and `image`. Without a type, the onebox doesn’t know what to do.

Hmm it looks like only “type” is missing, can we infer that **if we have everything else?** Assume a very general type?
```
```
ooh also @zogstrip [it says in the spec](http://ogp.me/#types):
> No additional properties other than the basic ones. **Any non-marked up webpage should be treated as og:type website.**
So arguably _we are wrong here_.

Yeah, I was chatting with @eviltrout about that the other day. With the new whitelist everything, we should use the same approach as Facebook, that tries to fill as many tags as possible (like using `title` tag instead of `og:title` if the last doest exist).

Hi guys,
No rush, but when are you planning on having this fix ?
Thank you in advance.

@zogstrip will reply here when `og:type` inference is in. I see very little risk if the other necessary fields are present.
I suppose we could also safely infer `og:title` as @falco says, using the HTML `` tag, but I am not sure we ever want to infer description or image.

Yeah, inferring can result into some strange results:
