Google Search has been the search engine world leader both in terms of search quality and user experience. Google has maintained that position for a very long time with over 90% market share of search engine users up to in Vietnam. One reason for this dominance is "simply because Google is always best".
Google Search Priority:
Keywords in url
Keywords in title
Keywords appear in the header tag or tags h1
Backlinks, lots of backlinks. Google prioritize quality over quantity backlinks. This is equivalent to "The popularity of the link".
Anchor text related to the theme and content of the website, both from outside and inside the website.
Keywords secondary, with numbers big enough to balance with the amount of primary keys.
New content. The site is constantly adding new content will be Google preferred. This is why Google is preferred blogs, especially popular blogs.
Google seems to like the site rather than commercial sites. This is why all kinds of this website tend to predominate in the SERPs for a number of keywords and controlled for most business owners have headaches available.
Google Search dislikes:
The structure of these duplicate pages on 1 site
The duplication of content
Optimization overboard (spam keywords in the content)
Too many low quality links to the site and exchange links or the links work in general
Yahoo wants to be like Google and imitated a lot from Google. This may be the reason why Yahoo's second-largest market share in Vietnam after Google (although recently the share of this stuff tends to decrease and to fall into the hands of Bing and Google). Search engines also tend priority and non-priority things like Google Search, but there are some notable differences between the two leading search engines, the thing that would make Yahoo ! somewhat easily dominate than Google.
First, the direct opposite of Google, Yahoo tend to prefer e-commerce sites over the information pages. This is a competitive method is quite effective search tool, stripping out the e-commerce business provides a significant revenue source for any search engine.
Second, Yahoo! also uses methods that save the underlying index or the word means the same in its algorithm, but the store is not extensive indexing by Google. Therefore, the results of Yahoo! are always fond of literally than Google. Moreover finding "exact match" keyword instead of searching the word "appropriate" as Google have been doing is making the search results of Yahoo paucity of content and less relevant than Google.
The use of search terms "exact match" also makes email filtering spam tools is somewhat restrictive than Google, which makes all emails are likely to be considered spam. People also say that finding appropriate keywords that Google can make this tool easy to be "fool", but personally I find this search algorithm of Yahoo! was and pulling the search engines are becoming obsolete than Google.
Next, Yahoo than Google Backlinks respected, both in quantity as well as quality Backlinks.
Yahoo! trust meta keywords and description tags than Google. When a site owner wants to improve website ranking on Yahoo !, this is the position they started editing. Creating description tags, meta keywords, content on pages, and other card-related titles and are optimized usually effective immediately for investors SEO for search engines.
