Microsoft & Yahoo join Google’s sitemap-protocol
years after the big search-players agreed on nofollow-directives and robots.txt-controlled exclusions, Danny Sullivan reports that Microsoft & Yahoo have announced to join Google’s sitemap-effort, an XML-protocol allowing webmasters to optimize the crawling of dynamic web-content:
Overall, I’m thrilled. It took nearly a decade for the search engines to go from unifying around standards for blocking spidering and making page description to agreeing on the nofollow attribute for links in January 2005. A wait of nearly two years for the next unified move is a long time, but far less than 10 and progress that’s very welcomed. I applaud the three search engines for all coming together and look forward to more to come.
