If you want to find a job in SEM, where is the best place to start?

SEM has a good trend now, with a good employment direction and of course a good salary. Need to be able to withstand high-intensity work pressure and often work overtime. If you have SEM experience, it is possible to be an optimizer directly, and it will be implemented everywhere without experience. It's certainly good to go to big companies like Ed and Zibolan. You can hold the giant's hand ... but don't give up the small company, that's where you can really learn. Big companies have a lot of hidden corporate politics, which is difficult to develop ... for reference only.
