Google's Matt Cutts explained this in a video: "The amount of PageRank that dissipates through a 301 is currently identical to the amount of PageRank that dissipates through a link."
In other words: it's okay to redirect an old URL to a new URL and the links that point to the old URL won't lose any value.
Bing introduces new Sitemaps tool
"SEO is a complex and ever changing area but there are some key elements that are still as relevant now as they were a few years ago. One of them is building high-quality XML Sitemaps, a comprehensive and accurate representation of your website. [...]20% of all clicks go to the same five websites
Because XML Sitemaps are so important, we want to make it very easy for webmasters to generate them and publish them for the use of all search engines. That’s why we are excited to open today the public beta program for the Bing Sitemap Plugin, an open source server-side technology that takes care of generating XML Sitemaps compliant with sitemaps.org for websites running on IIS as well as Apache." Editor's note: There's no need to install complicated plugins in your server software. You can use the XML Sitemap tool in the website audit tool of SEOprofiler to quickly create an XML Sitemap of your website.
"Five Websites [Facebook, YouTube, Yahoo, Wikipedia, Amazon] captured 20 percent of all search activity in Q4 2012, while the top 500 captured nearly 50 percent. Expansion to the top 1,000 Websites reached nearly 75 percent [...]
Even through paid search, the landscape changes very little — the top 10 Websites captured 16 percent of all paid search clicks, and the top 500 captured 56 percent." Editor's note: if you want to be found on the first result page, you must do the right things.
Google: a reminder about selling links that pass PageRank
"Please be wary if someone approaches you and wants to pay you for links or 'advertorial' pages on your site that pass PageRank. Selling links (or entire advertorial pages with embedded links) that pass PageRank violates our quality guidelines, and Google does take action on such violations.
The consequences for a linkselling site start with losing trust in Google's search results, as well as reduction of the site's visible PageRank in the Google Toolbar. The consequences can also include lower rankings for that site in Google's search results." Editor's note: It seems that these rules to not apply to Google. They continue to buy links from other sites.
