Certifications serve as proof that you received formal training for a skill and not did not just learn it on the job. The number of certifications may also be indicative of your dedication to increasing your knowledge and skill base. Technology in this area is always changing and keeping your skills up to date is vital, so recency of training and certifications could likely be taken into account. If you haven't had the opportunity to work towards any certifications, mention what training you receive on a regular basis to ensure you are up to date on all the technological advancements in your field.
