Facebook – Hiding job title on blogs using Facebook comments

Facebook will use any open graph meta tags if present for the title, and image etc (eg, og:title). The facebook documentation for Open Graph Protocol explains this in more detail:

The Open Graph protocol defines four required properties:

og:title - The title of your object as it should appear within the graph, e.g., "The Rock".

og:type - The type of your object, e.g., "movie". See the complete list of supported types.

og:image - An image URL which should represent your object within the graph. The image must be at least 50px by 50px and have a maximum aspect ratio of 3:1.

og:url - The canonical URL of your object that will be used as its permanent ID in the graph, e.g., http://www.imdb.com/title/tt0117500/.

In addition, we've extended the basic meta data to add two required fields to connect your page with Facebook:

og:site_name - A human-readable name for your site, e.g., "IMDb".

fb:admins or fb:app_id - A comma-separated list of either Facebook user IDs or a Facebook Platform application ID that administers this page. It is valid to include both fb:admins and fb:app_id on your page.

It's also recommended that you include the following property as well as these multi-part properties.

og:description - A one to two sentence description of your page.

I'm not sure how they do it for pages lacking these tags. If you're trying to duplicate this functionality then this is no help, sorry. But if you're trying to ensure your pages show up in the Publisher as you want then maybe this will.

You can also use the facebook opengraph debugger, which will provide info about your preview as well as (super handy) update their cached link if you make changes. Otherwise you can make changes to a link you want to share and the changes will not show up for days:

Are you referring to your News Feed (Top News), News Feed (Most Recent), or the Recent Activity on your profile?

I think that News Feed (Top News) only displays what Facebook considers to be most interesting to you, so I wouldn't expect your own likes/comments there. The News Feed setting that you mentioned applies to the Most Recent setting.

News Feed (Most Recent) does not display individual stories for comments and likes on posts; you would only see them under the corresponding post, if it is expanded. Are you saying that you expanded the likes/comments and you can see comments from other people but your comment is not there? Sometimes it takes some time for it to show up although it shouldn't take days (unless it was deleted).

If you are referring to the Recent Activity on your profile, there is an additional setting for that that you didn't mention. On your profile's Wall (not your News Feed), scroll to the bottom and click Edit Options. If you have hidden any kinds of stories from your Recent Activity these will be listed and you can unhide any of them by clicking the X and then Save.

As for the Photos tab, that used to be a known issue although the link to Facebook Help in that answer does not seem to work now. I don't know if that means that it should be fixed.
