2020 has come! But… oops, where did the time go? It’s already March! Belated as it is, it’s time for a refresh of 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:

  • 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.

  • $\begingroup$ @ JNat what's with not having a twitter-bot ad to pile the hate onto? The bot came up recently here -- not that I want to add to your worries about aging infrastructure that is causing new users to feel unwelcome ;-). $\endgroup$ Commented Mar 5, 2020 at 23:31
  • $\begingroup$ In case folks are missing high-scoring ads from previous runs -- for now I'm only pulling the lower-performing rung of the ads I've designed, to give them a longer chance for consideration. Let's hold off on importing the staples for now, and I promise I'll pull them in once this gathers some more steam. $\endgroup$ Commented Mar 5, 2020 at 23:35

    $\begingroup$ If it's all the same to you, please refrain from re-posting graphics I've authored to this thread (and if you do, please attribute the 'original' source correctly). I will do a full import shortly, once the lower-visibility ads have had some time closer to the top. $\endgroup$ Commented Mar 7, 2020 at 23:05
