The Challenge is open to higher education students from undergraduate or graduate programs, regardless of major. Students must form teams of 2-5 members and register under a verified faculty member, lecturer or instructor currently employed by an accredited higher education institute. Google will partner student teams with select nonprofits that are a part of the Ad Grants program and have opted in to participate in the Challenge.
The social media landscape is constantly evolving. New networks rise to prominence (e.g. Snapchat), new technology increases user participation and real-time content (e.g. Periscope) and existing networks enhance their platform and product (e.g. Facebook,Twitter, Pinterest and Instagram launching ‘buy’ buttons). Organic reach is also shrinking as the leading networks ramp up their paid channels to monetise platform investment.
The fee structure is both a filter against superfluous submissions and a revenue generator. Typically, the fee covers an annual subscription for one webpage, which will automatically be catalogued on a regular basis. However, some companies are experimenting with non-subscription based fee structures where purchased listings are displayed permanently. A per-click fee may also apply. Each search engine is different. Some sites allow only paid inclusion, although these have had little success. More frequently, many search engines, like Yahoo!, mix paid inclusion (per-page and per-click fee) with results from web crawling. Others, like Google (and as of 2006, Ask.com), do not let webmasters pay to be in their search engine listing (advertisements are shown separately and labeled as such).
Remember when you used to rely solely on search engines for traffic? Remember when you worked on SEO and lived and died by your placement in Google? Were you #1? Assured success. Well, okay, maybe not assured. Success only came if the keywords were relevant to your site users, but it was the only real roadmap to generating site traffic and revenue.
