It's almost February in 2018, which isn't supposed to be the proper time to cycle these, but for this year it'll be once again, so we'll be refreshing the Community Promotion Ads for this year now!

What are Community Promotion Ads?

Community Promotion Ads are community-vetted advertisements that will show up on the main site, in the right sidebar. The purpose of this question is the vetting process. Images of the advertisements are provided, and community voting will enable the advertisements to be shown.

Why do we have Community Promotion Ads?

This is a method for the community to control what gets promoted to visitors on the site. For example, you might promote the following things:

  • the site's twitter account
  • academic websites and resources
  • interesting campus story blogs
  • cool events or conferences
  • anything else your community would genuinely be interested in

The goal is for future visitors to find out about the stuff your community deems important. This also serves as a way to promote information and resources that are relevant to your own community's interests, both for those already in the community and those yet to join.

Why do we reset the ads every year?

Some services will maintain usefulness over the years, while other things will wane to allow for new faces to show up. Resetting the ads every year helps accommodate this, and allows old ads that have served their purpose to be cycled out for fresher ads for newer things. This helps keep the material in the ads relevant to not just the subject matter of the community, but to the current status of the community. We reset the ads once a year, every December.

The community promotion ads have no restrictions against reposting an ad from a previous cycle. If a particular service or ad is very valuable to the community and will continue to be so, it is a good idea to repost it. It may be helpful to give it a new face in the process, so as to prevent the imagery of the ad from getting stale after a year of exposure.

How does it work?

The answers you post to this question must conform to the following rules, or they will be ignored.

  1. All answers should be in the exact form of:

    [![Tagline to show on mouseover][1]][2]
       [1]: http://image-url
       [2]: http://clickthrough-url 

    Please do not add anything else to the body of the post. If you want to discuss something, do it in the comments.

  2. The question must always be tagged with the magic tag. In addition to enabling the functionality of the advertisements, this tag also pre-fills the answer form with the above required form.

Image requirements

  • The image that you create must be 300 x 250 pixels, or double that if high DPI.
  • Must be hosted through our standard image uploader (imgur)
  • Must be GIF or PNG
  • No animated GIFs
  • Absolute limit on file size of 150 KB
  • If the background of the image is white or partially white, there must be a 1px border (2px if high DPI) surrounding it.

Score Threshold

There is a minimum score threshold an answer must meet (currently 6) before it will be shown on the main site.

You can check out the ads that have met the threshold with basic click stats here.

  • Could we get an option to vote for "no ads"? Commented Feb 3, 2018 at 10:46
  • @FedericoPoloni I think then we just get auto ads. As it stands, none of the ads have enough votes to run.

  • @StrongBad I mean, "no ads", not "ads automatically chosen by the SE network". Just nothing in the page instead of a community ad. Commented Feb 11, 2018 at 9:35
  • @FedericoPoloni I guess I can't see the objection to ads in general. The ads are very unobtrusive and I can't picture a negative to almost any community approved content being displayed.

  • @Tyberius That's just, like, your opinion. Mine is different. A big block of green or orange/blue looks quite distracting to me, and it pushes down further into the page other content that I am interested in. Since ultimately no one gains money from these ads, I find quite pointless to have them displayed very prominently in the home page. Commented Feb 19, 2018 at 19:47
  • @FedericoPoloni thats understandable. I was just curious of your reasoning. It should arguably be an option then, though the question then becomes what the criteria would need to be for that option to win.

  • This is a demonstration post to indicate how this should look when an ad is posted. It also doubles as your twitter ad, but it's up to you if you wish to promote it by voting

  • I love the Physics Overflow concept! That said, there're a few implementation shortcomings that make it difficult to up-vote the ads just yet. The largest is just that account migration isn't so convenient. It seems like you'd have a lot better conversion rates if it were just a few clicks to extend one's account, or at least the question of migration were addressed more clearly.
