As one of China's three major search, Yahoo, itself also control huge traffic. Or most of the customers are looking at Baidu and GG, in fact, optimize the good Yahoo, the effect is not bad, after all, for a site, thousands of tens of thousands of of the flow is already a good performance, and these flows, for these three search, are not even bucket.
Optimize the customer site, trying to get a good ranking on the major search engines, the algorithm itself will create a lot of problems, because Yahoo algorithm and Google and Baidu are not the same. The Yahoo algorithm is based on the Inktomi algorithm introduced in 2002, so it was done to keep Google from using their search results. To get a good ranking on Yahoo, the following issues must be addressed:
1, keyword density
According to the current most SEO default the best keyword density to set the site's keyword density is not sensible, for 2:1, if you write articles and you read when there is a time lag, specific numbers are likely to lead you to the wrong direction; You must analyze your opponent's website and then determine the keyword density that best suits your site. Keyword density is good, but also with the industry and the type of website, so, the first to do a comprehensive analysis of the site is very necessary.
In addition, the best keyword density will periodically change, so you have to periodically on the original density of the analysis, and ranked in the top 10 of the site to compare to ensure that your keyword density is still the best list. Generally require density can be ranked in the top 10 before the good, not necessarily the first. Ranked first in the risk is also relatively large, a friend of the "free novel network" To do the first, the results are every day by people malicious attack or be completely imitated. To use facts to speak is the best basis.
2. Website structure
No search engine is more focused on the site structure than Yahoo. Although the importance of the site structure is reflected in many aspects, but when we asked the home page and key internal structure to comply with the standard, it is Yahoo let Beanstalk found that the site structure of the results produced the most significant impact.
Why is the site structure so important? The reason is 2:1, the station structure determines the page content priority order, also decides which content can obtain the highest priority, first by the search engine to find. At this point, the search engine generally gives the content of the top half of the page code more weight. Second, a reasonable structure of the site, through the use of CSS language, you can simplify the code, reduce the use of tables and so on. The simplification of the code allows the content to be displayed in a more visible position (ie, higher position), so that the search engine will be more attention, naturally, can also get the larger weight of the search engine.
3. Inner Chain
Like other search engines, in any ranking competition stage, a large number of high-quality internal chain with appropriate anchor text is a magic weapon to win. About the internal chain calculation method, Yahoo and Google, more than MSN is much simpler. For Yahoo to do optimization, link building to consider the following factors:
Website quality-for example, Google, has been using PR to distinguish the quality of the site, now also intends to apply TrustRank, in short, in Yahoo also, the number of links alone is not used, many times the quality of the link is more important. There is also a point must be noted that the PR is Google's calculation method, not Yahoo, so, in Yahoo to do optimization, the PR value can not determine the quality of the link. However, the PR can be used as a reference standard, however, the final decision to let Yahoo link quality of the factors are: For a keyword, link standing in the Yahoo rankings. Ranked high, Yahoo believes that the quality of the station, and vice versa, the link station is related to the content of the site, the chain to stay with other Yahoo high ranking sites to establish links, this link is from the trusted domain name. The trusted domain name referred to herein refers to any link with a certain quantity and quality, and at least a certain number of links, that exist for more than 3 years.
Link layout-The arrangement of links on the page is important in each major search engine. Links at the top or near the top of the page are more valuable than those located at the bottom or near the bottom. In addition, if there are other links on the page, the number of other links is inversely proportional to the effect on your ranking.
Anchor text-the anchor text linked to the website or the content of the page can be highlighted from the keyword. At the same time, for search engines, it is much more valuable to have anchor text appearing in the content than in a catalog format above a description.
For example, romantic novels, links to the corresponding novel columns, love Stories is the anchor text.
Non-friendship links-of course, the link in the Yahoo also is not a total no effect, but these links must be with a directory listing form of the non-friendship links, or other one-way links.
4, the new and old degree of the website
Mention the new site rankings, people will think of Google's "sandbox effect", in fact, Yahoo also has a corresponding policy, although to a degree than Google Light, time is shorter than Google. New sites and links cannot be given the same weight as old sites that exist for longer periods of time under the same conditions. The curbs on the new site have been promoted on Yahoo in the past two years, but not as serious as Google. Even if everything has been done in place, the new site is still not able to achieve a good ranking in 6 months, especially the competitive keywords. For the new site also has a difficult point is the search engine on the site to recognize the lag link. Search engines take it for granted that new sites are not linked. 3, 4 months later, site links will be the corresponding attention.
All this lag in recognition of the new site makes it difficult for new sites to get a good ranking in Google within 8-12 months. However, Yahoo's restrictions are not so strong, so the new stations that have been snowed in at the bottom of Google's search results can get high rankings on Yahoo.
