The impact of the frequency of keywords on ranking

The image above shows how SEOmoz's keywords appear on the page and how it affects rankings. Because SEOmoz in 2011 search Engine ranking factor and so on many articles, uses to Spearman rank correlation coefficient and so on the comparative scientific statistical method, therefore may speculate this chart is also through the statistical computation obtains the objective conclusion, has the big reference significance.

You can see that the key words as long as there is a certain effect, within a certain range of frequency, the effect is better. But beyond this range, the effect on the rankings will come down at a faster rate.

The author several months ago also collected data from Baidu, the number of keywords for Baidu and ranked the relationship between the numbers of rough statistical analysis. At that time only analyzed the text of the number of keywords, in conclusion, the final data summary generated by the chart and the above one is very similar.

So you can see that, too, the keyword appropriate number of occurrences is the best.

But the first time I contact SEO, there are some misunderstandings, there may be many people have such a misunderstanding, that SEO is there is "excessive" said-for example, the number of keywords appear more and better, as long as not to touch the bottom line of the search engine so that it K. As can be seen from the diagram, this is not appropriate to say, even if the optimal frequency of excess effect, the effect is gradually diminishing. From common sense it is easy to explain why the effect is gradually decreasing rather than exceeding a threshold to empty directly, because the search engine is not the purpose of the SEO and to provide users with better content. But this kind of common sense is easily overlooked in SEO.

If you look at these and want to adjust the frequency of the keywords on your site, it can be said that this is not necessary in most cases, unless the frequency is too high to be lowered.

From the data, SEOMOZ 2011 Statistical data, the number of keyword occurrences and rankings between the correlation coefficient is only 0.07, and Baidu above the author's rough statistic is about 0.2. In general, the significance of these numbers is that for Google, the number of keyword occurrences of the increase, although advantageous rankings, but the effect is small to be directly ignored; for Baidu, the number of keywords appear on the ranking of the impact is very small, there is no need to deliberately for it.

Even in special circumstances, want to use a certain page to ensure a certain keyword ranking, the title appears once, the body appears once or more.

Multi-Keyword Deployment

When the site has a bunch of columns, what columns should be merged with other columns, and what columns should be separated? The above picture is a good solution to this problem, and no longer do more elaboration. In short, the search engine will be based on the user's point of view, and strive to let searchers get the best search experience, so in most cases, for the user experience first consideration will be more helpful to SEO.

The previous mentioned keywords appear frequency, just to let everyone have a knowledge of it to write out, but it is not important, even if it is simply insignificant, but often see a lot of people still pay attention to such things. But the deployment of keywords, some people do not pay much attention, it is very very important. In Business-to-business, the field of business, SEO is not the strongest of the people to imitate the Alibaba, is not the Orchid pavilion and so on, although famous but do not value SEO site. Some of the site's SEO is not high-profile, but do very well, the field of the most excellent site is mainly dependent on a reasonable keyword deployment.

Keywords appear frequency and multiple keyword deployment Two, the former is a mere formality and has not considered the user, so it will not have much effect, at least no site depends on its success, the latter is precisely the category of information architecture, because in the name of the column deployment, it is necessary to involve the classification of column content adjustment, Ultimately, it will make it easier for users to find the content they want, and fundamentally improve the user experience (more accurately the searcher's information search experience), so it can achieve great results.

So, the direction should be clear?
