What is SEM and is there any difference between it and SEO?

SEM costs money to have a ranking.

SEM generally refers to search engine marketing, in the Internet this SEM specifically refers to the bidding promotion of search engines, through keyword bidding to obtain the ranking of advertising space**, according to the CPC click charge, showing the promotion style that does not generate costs, this style of promotion is flexible, the cost is controllable, click charges, according to the promotion of the region, the setting of the length of the promotion is relatively high, the ranking is stable, and the ranking is in the case of bidding.

SEO specifically refers to the search engine optimization to obtain the ranking of the snapshot position below the advertising space**, click on the promotion style without charge, can be outsourced to the network company fee optimization, can recruit their own technical personnel to optimize the labor cost, this style on the surface of the cost is slightly lower, the cycle is long, the ranking is unstable, relying on the weight of the information crawled by the search engine to determine the ranking, by the change of the search engine algorithm and the ranking changes, can only be said to have a chance to get a good ranking.

SEM is officially authorized**, this can be queried through the official query, SEO is currently chaotic, it can be said that most of the network companies have this business.

SEM is a money spent**. SEO is free to promote.

Generally speaking, SEM is all about opening an account to pay for a promotion. You'll need to optimize your account and set a daily fee. Use search engine advertising system rankings to help you bring in business. It means spending money.

SEO and SEM are often used together. That's the only way we can do better, because many first-time customers don't like to see ads for SEMs that they pay for directly. Will find some free, free is SEO, so you don't miss out on guests.

Therefore, if you do SEO, SEO has to be done in a coordinated manner, and it is not good to do SEO alone. Because the ** of the traffic is relatively single, it is only on the free side, and only one keyword is possible. Because it's hard to do keywords.

SEM doesn't have this problem, what keywords do you want to do, as long as you set your keywords, there is no need to optimize one keyword at a time.

It has been suggested that these two tools should be used together.
