Keep in mind that mid-sized and large companies use applicant tracking systems (ATS) to import and manage resumes. Heavy formatting can create issues when your resume is imported into an ATS, so keep it simple with clean bullets and fonts. Avoid pictures or videos unless your career industry demands it. Heavily formatted resumes should be sent directly to a person, not a system.
It's perfectly acceptable and highly recommended to develop multiple resume versions. This allows you to customize and taylor a resume to the specifics of an individual job opportunity. Keywords are critical to being noticed. If your resume is processed by an ATS, this automated system might accept or reject you on the basis of keywords before any human being every looks at your resume. Tweak your content as needed to match keywords in the job description that reflect your experience.

Recruiters use keyword searches to find candidates for opportunities. Load up your summary section with relevant keywords. Review similar LI profiles to review effective verbage.

An option to consider is to create and deploy a separate email address for job searches, especially if your personal email is less than professional (ie: firstname.lastname@example.org). And while you're at it, know that email addresses by the more technically literate are more likely to be associated with gmail.com, apple.com, and other more current ISPs. Hanging onto old email addresses (yahoo, aol, excite) indicates a certain sluggishness toward current digital trends.
Consider purchasing a domain that uses your actual name or company name. (Examples: email@example.com or firstname.lastname@example.org) This gives a professional look, the cost is very low.
