Since ancient times, "the goodness" is "good".In the process of integrating marketing, SEO's role is very large. At the same time, it also needs to be very refined in the process of search rankings. There are many capabilities, and many SEO masters have also flourished, but promotion, marketingCan't forget, push it.Doing things to do things with people who have truly help, to help good companies to implement marketing promotion, to work for their pro-SEO, especially many people closely associated with people.The catering industry, medical industry, especially the medical industry, the chaos in the past few years, after the event broadcast, as a promotion / marketing / seo / sem / media promotion must have a deep understanding, that isIt's nothing to do, not evil.We are not difficult to find that in the medical incident, the promoters have played the role of promotion, but they are also in invisible, there is a potential push, so any promoters need to be promoted.Licensed guidelines.Then, from the usual promotion model, station group, the station group has the three modes of the inner station group / pan-station group / garbage station group.The white hat technique in SE is often used by the inner station, which is under a primary domain name, parsing a lot of secondary domain names, as long as the content is much, constantly updating each secondary domain name to improve weight, for the weight of the primary domainIt will also be very fast, and the inner station group is often applied to websites that are implemented in size (product, region).Such as: Main domain: ****.COM / second domain name: ****.Combj.****.COMSZ.****.CoM setting, usually the primary domain is binding directly on the WWW secondary domain name, and the page has a lot of websites default WWW for the default overall station group home page.Internally, the internal station group is very wide, and the weight can be transmitted to a benign loop. The secondary site is constantly updating the content, and the weight of the primary site can be improved. The main site can also divide the weight to each secondary site.As long as you can constantly update the content, and increasing the interaction of the outer chain, the interaction of weights is increasing, and it is very good to improve the information of the website, and it is also very good for the development of the website.Therefore, the inner station group will ensure the quality of the content. If you continue to maintain, you can upgrade the results of the website. If the website does not update the second-level site, the last effect is only the power of the main station,Affect the ranking of the overall station group.There are also some industries in the second-level domain name of the interior station, which will add a three-level domain name. This effect is not good, or can be said to be a snake to add enough, without any business will have a lot of people to maintain a profile to produce an effect.The profitable website will not truly integrate the three-level domain name, that is, the pressure of the object is great.Regardless of whether it is said that the internal station group is implemented for the rankings of the primary keyword. It is also for the effect of the long tail, and it is possible to upgrade to the high-screen display, in searching a primary keyword, maybe the home page is the main station of the website,The back page of the search results is the secondary site, so invisible to enhance the website in the website in the keyword, and you can get the website to get better popularity.Now, the pan-station group is usually more business, and then opened up a lot of new domain names, one enterprise website and distributes different business, in a large company, many websites enhance ranking.Of course, a key website, then give the company's related business to transfer weights, through content exchange, distribute weights, of course, there is a problem with such pan-station groups, the key main station cannot have too much export link,To balance other business to support to improve rankings.The pan-station group should pay attention to the export link, moderately export, and the domain name must be legal and must have reasonable planning.There are a lot of pan-station groups to give the branch office, in this case, in fact, the company is inciting the ranking, it is necessary to make a reasonable unity, as for how to promote, there is a unified provision, after all, the pan-station group is alsoIt is necessary to maintain a large number of people to maintain, whether the company's expenditure supports a large number of personnel expenditures, and now the search engine is strictly compressed, especially in the station group, which is the final affected by many pan-station groups.The garbage station group is more serious, in the pan-station group system, the garbage station group is confused, and the crazy station group marketing refers to the garbage station group, especially similar domain names, in fact, the search results make users confuse, and medical careIn the industry, the garbage station group makes users easily improving.The garbage station group is usually a similar domain name generated by the key website, continuously obtaining weight delivery, then regenerates into a small website, increasing the number of station groups, get ranking with typing, many of the content, now a lot of search enginesAll of them have hit the garbage station, but we must also agree with the ability of SEO, and the SEO capability of the running garbage station group is also very strong. It adopts the principle of continuous fission sites, and can distribute one article into different spam, only needRecord some sites, and submit the included, you can get included, the garbage station group delivery weight, then get ranking, whether it is SEO / SEM is willing to adopt such a group plan, but confused, many people can't accept, the station group itselfCan do it, but use the station group to overlap the user, such a practice uses a certain industry, which is very harm to people, and many companies have taken into account when they adjust the business strategy.
