Many people can not figure out the concept of the two, there will be SEM is paid advertising, SEO is the natural ranking of the incorrect understanding,seo what is seo and this kind of talk is also more and more widely spread. In fact, it is easy to distinguish between the two, to give a small example, to the search engine Baidu, in the search results page with the word advertising is SEM promotion, the rest is basically SEO optimization.

I. SEO and SEM definition

SEO's full English name is Search Engine Optimization, translated into Chinese is search engine optimization. That is, in the understanding of the search engine on the natural ranking of the mechanism of the impact of the construction of the website itself, including the site content, including the name, keywords, introduction, code, graphics and other aspects of the optimization, as well as the adjustment of off-site links and other optimization, so as to improve the site in the relevant search engines in the natural ranking, to obtain more traffic, will promote their own.

SEM refers to paid promotion in the search engine, to improve the website traffic of a kind of network marketing. SEM includes SEO, PPC (Pay Per Click), as well as a variety of forms of paid login.

II. The difference between SEO and SEM

With the rapid development of the Internet, a variety of websites more and more, and a website to be recognized by more people know, it is necessary to optimize and promote. Next, I speak from four aspects of SEM and SEO in website optimization is different.

1. Effective time

SEM website bidding ranking is based on the price, the higher the price ranking is also high. Bidding time is very fast, as long as the site on line, and in the corresponding search engine set up keywords, the price out of a reasonable, you can achieve immediate results.

SEO optimization is the most time-consuming, even if the competition is small keywords or long-tail words,wordpress saas it may take a few weeks to rank, if the competition is fierce, the keywords may take several weeks to see the effect.

2. Costs

SEM is a paid promotion, willing to spend money, there are effects, the general charges are in accordance with the amount of clicks, the competition is quite fierce, some popular words may have to burn hundreds or even thousands of a day, once you do not spend money, there is no ranking.

SEO is mainly rely on artificial to optimize, one-time charge, generally based on different keywords, pay in units of years, the cost is relatively SEM much lower.

3. User Precision

SEO is mainly based on user demand, Baidu algorithm, to adjust the optimization of the site, so that the site is more in line with the search engine's recommendation mechanism, better able to solve the user's needs, more popular with users, and naturally improve the search rankings.

SEM is a paid form of traffic, compared to SEO is a little bad, it brings traffic are not precise enough, the bounce rate is relatively high.

4. Ranking adaptability

SEM is generally specialized for one or more search engines to pay for clicks, its ranking does not apply to other platforms, does not have portability.

SEO and SEM are different, different search engine ranking algorithms, although a little different, but the principle is basically the same, the site in the various search engine rankings may appear some changes, but the overall rankings will not be very different.

To do a good job of a website, whether to choose to do SEM paid advertising or SEO optimization, mainly based on the current situation of the operating site to decide. In the starting stage, the natural ranking is very difficult to do up quickly, this time you can do a proper SEM bidding to increase visibility. And when the site has taken off, the cost of SEM bidding can be slowly reduced, or even stopped, of course, appropriate investment, the two combined together, the effect will certainly be better.
