So, first, I would cut it down to one page and reduce the amount of text overall. You want to get the maximum impact as quickly as possible because when I loaded it up and saw a wall of text, it immediately set my frame of mind to reading the whole thing being a chore.
That aside, your bullet points are all over the place. "Recently managed," "SEO optimizing," "Reviewing," "Planned," "4 years," "Responsible for," "During my time," and "Oversaw" are the starting phrases for your bullet points in your top two experience blocks. It's really jarring to read that, and ideally you'll want to start with verbs with consistent tense: managed, optimized, reviewed, planned, etc. Those are just examples where I used the verbs from your current job, though; you'll want to tune them up more and listen to the suggestions from other posters, as well as switch to current tense for your current job.
Anyway, that's just a start. I haven't had time to dig in, and I don't work in marketing, so I'll see if I have more to add later.
