At SMX West last week, Google, Yahoo and Live Search announced a collaborative effort to clean up the clutter of duplicate URLs on the Web. A new tag, called the canonical tag, will be recognized by the three major search engines, allowing site owners to indicate the preferred URL of a page.
The Problem with Non-Canonical URLs
As Vanessa Fox pointed out on Search Engine Land, multiple URLs which all point to the same Web page cause a duplicate content issue within the search engine indexes. There are several negative consequences of duplicate URLs. When a search engine recognizes a duplicated page it may choose to filter the result from SERPs, leaving the decision of which URL is preferred to the search engine rather than the site owner. Link popularity may also suffer due to duplicate URLs if the link popularity intended for a single page is split among multiple URLs. Furthermore, the ability to crawl a site may be diminished if the limited bandwidth dedicated to spider the site is used on duplicate pages.
The New Canonical Tag
The canonical tag works by telling the search engine where the preferred URL is located so that appropriate indexing can occur and link popularity can be properly attributed. Along with the official announcements which can be found on each search engine's blog, Matt Cutts has gathered several resources to help webmasters learn more about the new tag. WordPress wizard Joost de Valk has made canonical URL plugins/extensions available for WordPress, Magento and Drupal.
The Tag is a Precaution, Not a Solution
While hailed as a time and effort saver by SEOs, search engine representatives have been careful to warn against using the canonical tag as the only solution for duplicate URLs. Because the canonical tag is a recommendation and not a directive, each search engine has reserved the right to select which URL it provides to users. Therefore, it is important that webmasters continue to manage duplicate URLs as recommended before the creation of the canonical tag: 301 redirect non-canonical URLs to preferred URLs, specify preferred URLs in Webmaster Tools, submit preferred URLs via XML Sitemap, normalize URLs within your CMS, and link consistently to preferred URLs within your site.
Shuffles
On January 26, the nation was rocked by a slew of layoff announcements as more than 60,000 jobs were cut on a single day. That day has since been dubbed Bloody Monday, and the tech industry did not escape the event unscathed. For a look at how the tech sector has fared in the down-trending economy, TechCrunch is tracking tech layoffs.
Despite job losses occurring across the board, several industry heavyweights defied conventional thinking to pursue new ventures. A big BCI congratulations goes out to SEO super blogger Lisa Barone, former voice of the Bruce Clay, Inc. blog. Lisa parted ways with We Build Pages to form Outspoken Media with partners Rhea Drysdale and Rae Hoffman.
Prior to launching the company Rhea had also resigned from We Build Pages, as did Google Guidelines expert Patrick Sexton. Patrick has since launched GetListed.org with partner David Mihm.
Google CEO Eric Schmidt took on a new position as an international business advisor to Britain's Conservative Party. Co-founder of Apple, Steve Wozniak, became the chief scientist of Salt Lake City-based tech start-up Fusion-io. Kevin Ryan, well known for his role at the Search Engine Strategies conference series, was named chief marketing officer of WebVisible. Veteran marketer Eric Lander resigned from his position as organic search manager of ADP to work as an SEO and project management consultant.
A number of tech companies saw a shake up in share values and profits over the last month. Ask.com's parent company IAC performed worse than expected in the fourth quarter. Apple reported a 3.5 percent drop in shares following CEO Steve Jobs's announcement of medical leave. Logitech reported a 70 percent drop in third-quarter profit compared to last year. Intel Corp.'s Q4 profit plummeted 90 percent year over year. And IBM resisted the trend with a 12 percent increase in fourth-quarter profit. Start-ups were hard off as venture capital funding in the U.S. was down 71 percent in the fourth quarter.
In news of broad corporate layoffs, Forrester Research was rumored to have initiated a 2 percent cut of analyst positions. Microsoft confirmed that up to 5,000 jobs would be cut in the next 18 months. Digg announced a restructuring effort that would eliminate 10 percent of their workforce.
According to a report by Efficient Frontier, search marketing spend declined 8 percent in the final quarter of 2008, with ad prices dropping 50 percent year over year.
