How to optimize websites for Yahoo Search

HTML code optimization　　
Compared with Google and MSN, Yahoo! More attention to HTML code. Many tests have shown that errors in HTML files may have little or even no impact on Google or MSN, but they do not prevent the page from appearing on the front-end of serp; but in Yahoo! Is much less likely to succeed. Similarly, a website or webpage that has completely passed the W3C certification has fixed an HTML error. The changes in Google or MSN are hardly noticeable, but in Yahoo! But we can find a qualitative leap in rankings.
In webpage design and production, for Yahoo! The optimization mainly includes: 1. Yahoo! The content that appears in front of an HTML file (not the same as that displayed on a webpage) is important, this requires us to highlight the header of an HTML file as an important part of the page. 2. A well-designed webpage has mostly reduced code, for example, the use of external CSS files and JavaScript files can greatly reduce the size of HTML, and the efficiency of HTML code can be improved if you use less or do not use table at all, these can highlight the real content of the webpage to a large extent. In fact, the above two items cannot be ignored when optimizing other search engines, except Yahoo! Give it a higher weight.

　　 Keyword density
Because the search engine algorithms are always being adjusted, it is unrealistic to give specific keyword density. Moreover, the keyword density is not a perfect number, in many cases, the optimal keyword density varies with different website types in the industry. Therefore, the feasible method is to analyze the serp of the keyword corresponding to the website and analyze the keyword density used by the top 10 websites or webpages. After all, the ideal keyword density is always regular. In general, the top 10 Websites in Yahoo serp, according to the keyword competition, keyword density in addition to a few in 0.5 to 1.0% (low-end) and 5.0 to 8.0% (high-end, most of them are between them. At this time, we try to set the keyword density to a value slightly lower than the maximum value to achieve optimization.

　　 Reverse link
In terms of reverse link, the search engine rules in various aspects are certainly not much different, using the keyword anchor text on content-related websites is also a crucial factor in Yahoo ranking algorithms. In comparison, Yahoo! The processing of reverse links is more similar to Google, with a slight difference from MSN.
For Yahoo! To optimize the Website, you must consider the following aspects:

　　 Link Quality
Similar to Google's method of determining the quality of reverse link using PageRank and trustrank, Yahoo! Similar technologies are used to remove irrelevant links or spam. Similarly, in Yahoo! In the ranking algorithm, the link quality is more important than the pure quantity.
In Google's website optimization, you can often weigh the quality of the link by checking the PageRank of The Link source website. Although the PageRank shown in the Google Toolbar is not accurate, but it is at least a relatively simple judgment basis. So how can we determine whether a link is determined by Yahoo as a high-quality link? The simple method is to check whether the source website of the link appears on Yahoo! The same or similar keyword serp is located at the front. For more accurate judgment, you also need to view the whois information of the website, Yahoo! It is generally believed that the domain name registration time of a website that can be depended on should be at least three years. In addition, it should also be checked whether the source website has a sufficient number of non-exchange links and the number of outbound links on the Source Page, the more outbound links on the same page, the smaller the influence, and so on.

　　 Link location
Similarly, you must pay attention to the location where the link appears on the page. Simply put, links that appear on the HTML front end are more effective than those that appear on the back end. links that use special formats (such as bold, italic, and other colors or fonts) are more effective.
Anchor text
We have discussed the anchor text of the link for many times! And will not be repeated.

　　 Unidirectional Link
Two-way exchange link in Yahoo! Is not completely ineffective, but its effect on rankings is far smaller than that of one-way, content-related links, because in many cases, such links are closer to the comments obtained for excellent content.
Influence of website or webpage time
Similar to Google's sandbox, Yahoo! Similar "Aging" mechanism is also used: it is difficult to obtain a good ranking when a new website is in operation for at least 6 months or longer, even if the optimization technology is used perfectly; at the same time, the new link will not soon play its due role in promoting rankings. It usually takes three to four months for the effect to gradually become apparent. However, compared with Google, Yahoo! This "test" mechanism is less powerful. However, the combined effect on new websites and new links often leads to many new websites (reverse links of new websites must be new links) it is difficult to obtain a good ranking for highly competitive keywords within a period of 8 months to 1 year.
