Lao Yang: How to analyze a website seo do good and bad

How to analyze a website seo whether do good and bad is not an easy thing, especially the analysis of reasonable in place, because a site SEO do good and bad not only from the site title and the rankings can be seen out. Since this is to say to analyze, then say my opinion. In addition to the emphasis here is to analyze the other site SEO do good or bad, rather than analysis of competing opponents, so here does not make the site inherent factor analysis, such as domain name information and PR What, of course, can also be used as an analysis of competing opponents of a reference, nothing more than you do a job, is to analyze the opponent's domain name information. Let's get down to business:

First, intuitive feeling, Web page beautiful degree do good not directly affect the user's first feeling, art do good looks will make people feel very comfortable, users have to leave the possibility, a good SEO often pay attention to the user's experience, will be in the optimization and experience to find a reasonable balance point.

Second, the overall grasp, the most intuitive is to see the site's collection amount, the number of chain, keyword rankings.

1, included, you go to see a site collected more from a certain aspect of the SEO to do the better, but the light to see a collection and can not explain the problem, such as a site contains 100,000 pages, but his total page has tens of millions that is simply too bad. Their website can know the specific amount of information, and other people's station is not very accurate to know the total amount of information on other sites so light to see this can not be quantitative;

2, outside the chain, first of all, we think the more the more the more the better, this may be true, but the chain not only to have a quantity more to have quality;

3, keyword ranking, look at the site keyword rankings, ranking the more generally before the SEO do better, but this still does not explain the problem, because we generally go to check is someone else's target keyword ranking, and other people's long tail word ranking how? Maybe someone else's goal keyword ranking is not very good, but his long tail does well, Site traffic can do very well, so at this time we have to consider the overall ranking of a site, and this data we are very difficult to learn from the station is another matter.

Third, the site source code analysis, through the source can see how the page layout and a number of various tags, JS use is reasonable.

1, the source code is concise enough, whether it is too long;

2, whether the use of div+css, we know div+css make the code more concise, reasonable label use more conducive to search crawling and crawl, and too many div nesting is not conducive to search crawling;

3, the structure of the head of the HTML is optimized, mainly reflected in the title (title), descriptive book is reasonable, the title to highlight the theme of both key words can not be stacked, describe whether to do nature;

4, the Use of Web page JS, JS Search can not crawl, not a lot of use, but reasonable use of JS can reduce the size of the Web page source;

5, the use of the URL is reasonable, URL parameters are too long, too complex.

Four, the website Foundation optimizes the analysis, mainly manifests in

1, whether to do a good job robot.txt;

2, whether 404, 301 pages;

3, the website URL is standardized;

4, the internal link is good, the site directory hierarchy is too much, too deep search is not crawled;

5, whether use good rel= "nofollow"

The above can simple analysis of a Web site SEO do good and bad, because of their own knowledge of the limitations are not comprehensive and accurate, please correct and corrected. As the beginning said, it's not easy to analyze a website because we do not have a comprehensive and accurate grasp of each other's site data, and often can only be taken out of context, and a site SEO do not do well, often to see from the overall, individual rankings or good or bad may not affect the development of the site, and only the overall performance of the site well , the website has the considerable flow, only then may achieve the profit maximization, the flow transformation maximization.
