This question already has an answer here:

The dawn of a new year, 2015, now approaches, or has already approached, either way it means that it is now time to reset our Community Promotion Ads!

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
  • useful tools or resources for physics research
  • interesting articles or findings for the curious
  • 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 220 x 250 pixels
  • 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

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.

Tagline to show on mouseover

  • This is displaying "Tagline to show on mouseover". Can you fix that please: perhaps explain what this is advertising? – ChrisW May 26 '15 at 7:50
  • @ChrisW: Point 1 in the OP says I cannot (it must be in the exact form as the template). I thought it was clear what it was advertising, but it's a script that allows you to have MathJax (Latex) hotkeys in the normal site edit box. – Kyle Kanos May 26 '15 at 14:28
  • Same 'form' as the template but different 'content': look at for example, all the other advertisements contain informative mouse-over text. When I saw this advertisement, I couldn't discover what it was advertising. – ChrisW May 26 '15 at 14:32
  • @ChrisW: Meh. Anyway, that mouse over text produces the same thing as what's on the body of the image so it seems extremely superfluous. Considering the image here explains precisely what it is, I'm not sure what problems you've run into. – Kyle Kanos May 26 '15 at 14:38
  • You say that this "physics editor" is a script: but, for example, I don't know where to get this script from. – ChrisW May 26 '15 at 15:42

    @ChrisW: You do realize that every single one of these ads on this site is a hyperlink to the thing they promote? So have you bothered to actually click the link? – Kyle Kanos May 26 '15 at 16:12

What if? Serious scientific answers to absurd hypothetical questions

  • I'm proposing this for Physics.SE, building on the fact that the same proposal in Academia.SE turned out to be quite popular, and I would expect some kind of parity between the xkcd-fetish in both communities. – The Dark Side Oct 24 '15 at 18:17

Follow us on Twitter!

  • 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. – Grace Note Jan 1 '15 at 3:09

    Why downvote? Site proposal ads are not permitted? – sepideh Aug 28 '15 at 17:15

    I would read downvotes on this as disagreement with the proposal or with that proposal as something we should advertise. Site proposal ads are perfectly allowed and (some) have been well received in the past - see the threads from previous years to get a feel for how the community tends to feel about these. – Emilio Pisanty Aug 28 '15 at 23:41
