In recent months it appears that that the world of journalism is using search engine optimization (SEO) to help draw attention to their articles and now a group of online news outlets have taken another step in increasing their online visibility.

Thomson Reuters announced today that the Huffington Post, DailyMe and the UK’s Mail Online will all be using the company’s OpenCalais service which Thomson Reuters says will allow the news organizations to better localize and personalize news while increasing their search engine optimization (SEO).

These agreements with the three news outlets follow the decision of Reuters and CNET to use the service and come one day after Thomson Reuters introduced additional services though OpenCalais including Spanish language support and the addition of "social tags," which the company says are "story descriptors in simple, everyday language."

Thomas Tague, Calais initiative lead at Thomson Reuters said an increase in search engine optimization (SEO) is just one of the benefits of the new services.

"With these updates, we are increasing the relevance, impact and appeal of the OpenCalais Service worldwide, for everything from content operations to SEO," he said. "Social Tags and Spanish language support are two of the most in-demand features with our partner publishers and community of web developers alike."

This is not the first foray into search engine optimization (SEO) for the Huffington Post. Earlier this year the news outlet released its publishing standards for articles written by citizen journalists and noted that the site reserved the right to make editorial changes for various reasons, including SEO.
