Improve Google Search Ranking !
SSL certificate has its benefits from enhanced security to a boost in search ranking as Google is giving a ranking boost to secure https/SSL sites.
Google says this gives websites a small ranking benefit, only counting as a “very lightweight signal” within the overall ranking algorithm. In fact, Google said this carries “less weight than other signals such as high-quality content.”
Based on their tests, Google says it has an impact on “fewer than 1% of global queries” but said they “may decide to strengthen” the signal because they want to “encourage all website owners to switch from HTTP to HTTPS to keep everyone safe on the web.”
Google also said based on their tests for the past few months, the HTTPS signal showed “positive results” in terms of relevancy and ranking in Google’s search results
