What are the differences and connections between SEO and SEM?

SEO in Chinese is called search engine optimization, which refers to optimizing the internal and external websites on the basis of understanding the natural ranking mechanism of search engines, improving the natural ranking of search engine keywords, so that the website can obtain more display and traffic, and attract more target customers. , so that enterprises and individuals can achieve the purpose of network promotion and brand building.

And what is SEM? SEM is called Search Engine Marketing in Chinese. What SEM does is to make full and effective use of search engines for online marketing and promotion. The following is the difference and connection between the two?

First, the cost varies greatly

In fact, you should also find that the cost of SEO and SEM is very different. Because relatively speaking, SEO is to improve website rankings through optimization inside and outside the site. This is a way to improve natural rankings. The price is also very favorable, and you only need to maintain your website. SEM is completely different, because this optimization method is mainly to display the website through payment, of course, it also needs to have a dedicated person to maintain the account, but it also needs to be adjusted in time, and the cost must be higher.

Second, the effect of the two is different

Strictly speaking, SEO definitely takes longer, maybe even a few months of optimization, but only seeing a very simple ranking improvement, not a good website ranking improvement. After the SEO ranking goes up, it can guarantee a good effect, and the daily nostalgia is also very high. But if you do SEM, you can see a lot of traffic in a short period of time, and you can also have a good marketing effect in a short period of time. We should pay special attention to overall measurements to see what solutions fit.

Three, the scope is different

In fact, SEO optimization also belongs to SEM. Although there are some parts of SEO optimization that do not cost money, doing SEO optimization yourself also requires a lot of costs, and the basic costs must be integrated and confirmed.

But relatively speaking, SEO is to optimize one's own website, but SEM includes basic optimization of the website, off-site promotion and some corresponding paid marketing, which can be said to cover a larger area.
