The size requirements for adverts have changed. It is NOT appropriate to simply copy over the images from previous years - they won't work. Images need to be 300×250px or 600×500px for retina displays, up from 220×250px in previous years. If an image is taller than it is wide, it's the wrong size.

It's 2016 now, and we've made some changes to the sidebar size. As such, we can now restart the Community Promotion Ads for 2016!

Keep in mind, we have updated some of the guidelines compared to previously - the changes are marked in bold in the Image Requirements section.

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 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.

    $\begingroup$ Also: can someone fill me in with why they're downvoting this post? I just don't see what the rationale is here and would like to understand. $\endgroup$

    $\begingroup$ @Emilio We're delaying the activation some bit to allow for sites that have lots of ads from the old width but haven't updated the widths to match yet. We're probably looking at some time February for that, but if we see a lot of ads being submitted at the new width then we'll push it sooner. $\endgroup$

  • $\begingroup$ @GraceNote Is there any update on the go-live date on the new ads? To me it looks like we are ready (as are e.g. math and academia). Or is the roll-out a single network-wide go? $\endgroup$ Commented Feb 13, 2016 at 15:19
  • $\begingroup$ Just heard that ads can be up to 150KB: meta.stackexchange.com/questions/273200/… $\endgroup$ Commented Feb 21, 2016 at 22:38

Auto-Latex Equations add-on for Google Docs

    $\begingroup$ I'm not quite sure I see the case here - we already have MathJax enabled on site. In any case, it would be better to have a more descriptive ad (i.e. specifically for the Auto-LaTeX Chrome add-on, rather than something that looks like a misleadingly generic LaTeX ad and turns out not to be. $\endgroup$ Commented Feb 17, 2016 at 23:27
  • $\begingroup$ @EmilioPisanty Well the Google docs logo is fairly wellknown, so I thought that would imply that the latex is for Google docs, hence the addon $\endgroup$ Commented Feb 18, 2016 at 5:12

  • $\begingroup$ This is a demonstration post to indicate how this should look when an ad is posted, now with 80px more width! It also doubles as your twitter ad, but it's up to you if you wish to promote it by voting. $\endgroup$

    $\begingroup$ Well, we should really check on the Twitter account each year and see whether its posts are things we want to promote. $\endgroup$
