This week was the big finish to the first global Google Science Fair. Earlier this year, we invited students aged 13 to 18 to submit science projects to this new competition. More than 10,000 young people from more than 90 countries sent in their entries. Two months ago, 15 projects were chosen as finalists. And last week, the members of those teams were flown to Google headquarters in Mountain View, California for the final judging. The winners:
  • Lauren Hodge (13-14 age group) for a study about reducing carcinogens in grilled chicken.
  • Naomi Shah (15-16) for her project relating better indoor air quality to a reduced need for asthma medication.
  • Shree Bose (17-18), who found a way to improve ovarian cancer treatment for certain patients.
Congratulations to the winners and to everyone who participated!

While you’re thinking about the great accomplishments of people so young, here’s another fact to make you ponder time in a different way: Neptune has just completed its first full orbit since its discovery in 1846, or just about one Neptune-year ago (that’s a little more than 164 Earth-years). Happy birthday (or something), Neptune.

Finally, I’m not sure if Neptune has any creatures that can match this remarkable rainbow toad. This animal was last seen in 1924 (right around half a Neptune-year ago) and had never been depicted in color before. This weekend, consider taking some time to go outside and see what you can discover.

What are Backlinks?

A back link is an inward link to your site that may or may not be reciprocated with an outward link back. If page A links to page B then a back link would be a link which goes from page B back to page A.
A backlink is just a link back to your site. In fact, if people called them "link backs" or just "links", we'd probably have a better idea of what is being discussed. A link just means that a site is embedding the url (address) into one of its pages, so that readers can click through from that site to yours.
Example: Site A links to Site B. We'd call that Site B having a backlink from Site A.

Why Backlinks Are Important

Backlinks are important for SEO because some search engines like Google, give more credit to websites that have a large number of quality backlinks, and consider those websites more relevant than others in their results pages for a search query.
Therefore, when search engines calculate the relevance of a site to a keyword, they not only consider the number of backlinks to that site but also their quality. In order to determine the quality, a search engine considers the content of the sites. When backlinks to your site come from other sites, and those sites have content related to your site, these backlinks are considered more relevant to your site. If backlinks are found on sites with unrelated content, they are considered less relevant. The higher the relevance of backlinks, the greater their quality.
For example, if a webmaster has a website about how to rescue orphaned dogs, and received a backlink from another website about dogs, then that would be more relevant in a search engine's assessment than say a link from a site about car racing. Therefore, higher the relevance of the site linking back to your website, the better the quality of the backlink.
Search engines want websites to have a level playing field, and look for natural links built slowly over time. While it is fairly easy to modify your webpages to make them more SEO friendly it is a lot harder for you to influence other websites and get them to link to your website. This is the reason search engines regard backlinks as a very important factor. Further, search engine's criteria for quality backlinks has gotten even tougher, thanks to unscrupulous webmasters trying to achieve these backlinks by deceptive or sneaky techniques, such as hidden links, or automatically generated pages whose sole purpose is to provide backlinks to websites. These pages are called link farms, and they are not only disregarded by search engines, but linking to a link farm could get your site banned entirely. 

Anchor Text

When a link incorporates a keyword into the text of the hyperlink, we call this anchor text. A link's anchor text may be one of the most powerful resources a webmaster has. Backlinks from multiple websites with the anchor text "orphaned dogs" would help your website rank higher for the keyword "orphaned dogs". Using your keyword is a superior way to utilize a hyperlink as against having links with words like "click here" which do not relate to your website. The 'Backlink Anchor Text Analysis Tool' is a tool which will assist you find your backlinks and the text which is being used to link to your website. If you find that your site is being linked to from another website, but the anchor text is not being utilized properly, you should request that the website change the anchor text to something which incorporates relevant keywords. This will also help boost your rankings.

Cross-posted with the Google Commerce Blog

Over the past year, the web application ecosystem has been growing at an accelerating pace. Faster browsers and powerful web platforms like HTML5 have enabled developers to switch from native code to web based apps.

That’s why the Google Chrome and Commerce teams are holding several HTML5 Web App hackathons around the United States in early August. This is a great opportunity for developers to socialize, network, and play with the latest web APIs. During the hackathons, we'll cover the end-to-end process of developing an HTML5 application, publicizing with Chrome Web Store, and finally monetizing with In-App Payments.

In true hackathon style, participants will have the opportunity to create teams and work on a project together. At the end of the day, participants will present what they have created, and vote on the best apps or games. And of course we’ll have some awesome prizes for the winners.

The event is free of charge but space is limited. For more information and to register, please visit the location-specific links below:

August 1, 2011: New York
August 3, 2011: Chicago
August 8, 2011: Seattle
August 11, 2011: Mountain View

We’re looking forward to seeing the applications and games you build!

Mihai Ionescu is a Developer Advocate at Google helping developers build compelling applications using open web technologies. In his free time, when not skiing in the Sierras, Mihai enjoys traveling and exploring the great outdoors with his family.
