>>9591801OK dude, so I can't really write lines for your CV for you without knowing way more about your work history and skills than is practical here, but a line like what I wrote doesn't really belong in your CV anyway -- it belongs in your cover letter. You can also say shit like that in the interview.
In your CV, you want to have a short paragraph that describes your background. Doesn't need to have complete sentences. Shit like, "Degrees in law and sociology. Particular background in [x area of law]. Excellent verbal and written communication skills. Proven track record of [yz]." You get the idea. It's fine if you have to inflate some of your accomplishments, everyone does it. Keep it to a few sentences, it really doesn't need to be much longer than that.
As far as your cover letter goes, I recommend that you say that you left your legal job to "seek new challenges" (a bullshit catch-all phrase that hiring managers like), which explains why you worked a series of random jobs that you didn't stay at for very long; then you worked freelance for the reasons I outlined in my prev. post. That's really all you need about your recent work experience in your cover letter, you want to keep it short.
If asked in the interview, you can say that you noticed a lot of law firms had very poor online content, with lots of "keyword stuffing" that was clearly incurring "SEO penalties" (look up what that means if you don't already know), and you saw an opportunity there, so you worked with them to improve their content marketing strategy. If you have enough know-how to write 1000-2000 word blog posts about literally any area of the law, even if they're pretty entry-level, then that is something you literally could do, by the way.
