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 the mathematically inclined
  • 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.

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.

  • $\begingroup$ Is it ok to use (and modify) logos of other websites. Do we need to have their approval of to look if they have something about licensing and stuff on their websites? For example Wikipedia mentions copyright here, I did not find something similar e.g. at proofwiki. Hopefully there is someone more knowledgable about this and it is quite probable that it was already discussed somewhere. $\endgroup$ Dec 11 '11 at 8:34

    $\begingroup$ -1. I find the style of this question unnecessarily off-putting. Does it really say, "But whyyyyyyyy"? On the main site, this style of question-asking is almost always a marker of a very poor question. Since I gather that this is a serious project, I suggest that the question be edited to a more matter-of-fact style. Otherwise, it would seem likely that you are driving away potentially talented participants. $\endgroup$

    $\begingroup$ Indeed so. I feel that this sort of ads campaign may be very useful for some other communities but I have strong doubts on it being useful for communities like this one. In my view, at least, this community has enough work as it is. The fact that the dominant tag is homework - and it gave a very nice head start to other tags - is enough to suggest that most of the transient users want an answer or two and that's it.

    $\begingroup$ @Asaf Alright. That's sensible, and thanks again for letting me know. The main reason we offer these community ads is to allow a community to control what is shown. Otherwise, the standard presentation is going to be the Area 51 ads and random questions from other sites. However, if it's already something that isn't going to be looked at out of reasons other than lack of interest, it makes sense that it won't really make any use to the community. $\endgroup$
