55 SEO Interview Questions
Interviewing and hiring SEOs has been on my mind recently as my team has been actively looking to expand. Such thoughts are part of what prompted me to update and re-publish an old post of mine on why a career in SEO may be a bad move. I'm not sure that all of the people that read my article also read my counter argument on why a career in SEO can also be a good move, but it certainly inspired some discussion, mostly disagreement. If you're inclined to pursue an SEO career either in-house or at an agency, one of the most important obstacles you'll need to get through is the barrage of interview questions that will be thrown at you.
About a third of these 55 interview questions are ones I thought of. The rest I picked from various postings around the web from people I think are worthy of attention. Credits are at the bottom.
Technical / Tactics
Every SEO prefers certain tactics over others, but familiarity with many could indicate a deeper understanding of the industry. And while every SEO doesn't need to have a web developer background, having such skills can help set someone apart from the crowd.
