Why? is all about quality, and thanks to its focus on the practical means by which information reaches consumers in the age of the internet, it’s also all about SEO. The MedlinePlus SEO strategy has helped the site attain unparalleled rankings, competing with the likes of Facebook and Twitter, by paying proper attention to the development of its meta descriptions.

“[Meta descriptions] help users know what to expect from a webpage,” MedlinePlus’ Kate Masterton and Katie Chan wrote recently in a blog post. “People are more likely to click through to the site when the meta description is well-written and precisely describes the content they seek, thereby providing an immediate boost to clicks and conversions.”

Meg Mader, a Bixal digital program manager who advised on NLM’s SEO strategy, points out that "Meta descriptions are a simple way to increase findability of pages. When done correctly, and within character count limits, meta descriptions can have a quick and positive impact on search engine ranking."

MedlinePlus simply analyzed the most searched-for terms for each and every page on its website using Google Adwords’ keyword planner tool. MedlinePlus used this same strategy for the Spanish meta descriptions. This wasn’t just a matter of translating the English meta descriptions into Spanish; MedlinePlus staff researched, wrote, and edited these meta descriptions as well. The same can (and should) be done for any other language, given the nuances often lost in translation.
