Record these records mainly to view the quality of the website and compare the results after optimization.
The steps for analyzing the homepage, category page, and content page are similar. You can view the page first, and then the Page code, and analyze it based on the knowledge points we mentioned earlier. The following is a detailed analysis. Here I chose Dangdang website. Why should I choose Dangdang website for optimization testing? I applied for a Dangdang agent two months ago to help Dangdang sell books and get commissions. I sold more than 10 thousand yuan of books in about a month, and I also got a lot of income.
In the ranking process, my website content comes from Dangdang, but the ranking is higher than Dangdang, so people can purchase books through Dangdang through my website. Now we are looking for a book from Dangdang. In the search results, Dangdang's website ranks very low. Think about it. If Dangdang has been optimized and most of the books are ranked, his sales volume will certainly be much larger than it is now. For users, it is easier to find Dangdang, which sells books.

Why check the number of domain names under this domain name? I am talking about an example. I used to create a website for the customer for a long time and went up on Google, but Baidu never changed. Later I discovered that, I used another domain name in Baidu.
The longer the domain name age is, the higher the ranking weight.

I. Home Page problems:
1 The homepage is redirected.
Problem: Using js to redirect is a redirection scam for search engines.
Solution: Use the 301 Method for redirection.
2. No meta is used on the home page of Row 5.
Q: The keyword description in Meta still works for Google.
Solution: add the meta attribute.
3. The webpage is bloated.
Problem:
1. ID = "all-categories" Name: 45 rows long
2. Target = "_ blank" appears for more than 50 rows
3. A large number of CSS lines appear on the page.
4. Style = "padding-left: 5px; padding-top: 5px;" 351 rows
5. There are a large number of 1871 rows of scripts at the end of the page
6. 1195 rows of extra Div labels
Solution:
1. ID = "AC ",
2. <base target = "_ blank">,
3. Place CSS in the CSS file, and then use <LINK rel = "stylesheet" type = "text/CSS" href = "/CSS/default.css"> to call
4. define these types in CSS
5. put it in the JS file, and then use <SCRIPT src = "/user/common/Ajax. JS "type =" text/JavaScript "Language =" javascript1.2 "charset =" gb2312 "> </SCRIPT> call
With the above simple modification, I changed the page from 130 to 110 without affecting any display effect.
6. Remove unnecessary Div
4. Some advertisement links on the home page of Row 1
Question: <Div class = "adtitle"> </div> the home page links are limited, with a maximum of 100 links. You need to display more of the most important links to the search engine.
Solution: Use JS, IFRAME, and other methods.
5. robots.txt is not set.
Problem: Sorry, of course, the premise is that this file exists on the website. For websites without robots.txt configured, SPIDER will be redirected to 404 documents-although it is not a pure text file-which will cause a lot of trouble for the SPIDER indexing website, this affects the search engine's indexing of website pages.
Solution: put an empty robots.txt file under the root directory.

The 6.165 rows page uses nested table
Problem: Nested tables will affect the search engine's internal content.
Solution: Use Div + CSS to reduce table depth.
7. nonstandard use of some labels
Problem: <link href = "*" rel = "stylesheet" type = "text/CSS"/> of the 18 rows can only be used in the head.
Solution: Move the link to the head label.
8. The Google sitemap XML file is not generated.
Problem: In normal times, the search engine performs indexing on its own initiative, while using sitemap, the search engine can passively obtain the page change content, allowing indexing to your content webpage faster, promptly discover web page problems. Currently, the following search engines are supported: Google, Yahoo, and MSN.
Solution: Reference page: Google sitemap Protocol
Ii. Classification page: http://list.dangdang.com/05.02.html
1. No meta is used.
Q: The keyword description in Meta still works for Google.
Solution: the keyword on the page with the meta attribute added can be a "TV series". The description is: Dangdang provides 5099 TV series. You are welcome to purchase them.
2. The webpage is bloated.
Problem:
1. A large number of CSS appear on the page 12
2. Target = "_ blank" appears multiple times 687
Solution:
1. Place CSS in the CSS file, and then use <LINK rel = "stylesheet" type = "text/CSS" href = "/CSS/default.css"> to call
2. <base target = "_ blank">,
3. The page uses nested table
Problem: Nested tables will affect the search engine's internal content.
Solution: Use Div + CSS to reduce table depth.
4. Each category has public content
Problem: for example, cash on delivery FAQ, too many features are not good for keyword density.
Solution: put this part in JS or IFRAME.
5. File Path Problems
Problem: it is not good to name a file in this format in 05.02.html, although the search engine has included this page.
Solution: The/05-02/directory method is recommended.
3. Terminal page:
Example: http://product.dangdang.com/product.aspx? Product_id = 9191819
1. The path is not static
Problem: search engines like static pages. For dynamic pages, to avoid link traps, search engines only include static files under dynamic pages. As a result, most pages cannot be indexed in time.
Solution: use the two optimization methods mentioned in my tutorial for static processing.
1. Static Processing Using iis_rewrite is suitable for PHP, ASP, and ASP. NET programs.
2. Use the webpage program developed by Asp.net and urlrewriter. DLL for static.
2. No attributes such as meta
Problem: The Meta attribute mainly appears in Google's search results, and the perfect Meta is used to optimize the search engine.
Solution: With a http://product.dangdang.com/product.aspx? Product_id = 9191819, for example,
Title: Growing troubles: full version of the first season
<Meta name = "Description" content = "Growing troubles: full version of the first quarter (Classic dubbing on top) (4dvd9) Market Price: 150 yuan Dangdang price: 88 yuan discount: off savings: 62.00 yuan ">
<Meta name = "keywords" content = "Growing troubles: full version of the first season">
Description is the first 120 Chinese characters of the content, and keyword is the keyword of the content. If there is no keyword, it is equal to the title.
3. Comparison of website Similarity
3. Each page has public content
Problem: for example, the pop-up window of 33 types of commodities on the top and the cash on delivery FAQ at the bottom. Too much irrelevant content is detrimental to the keyword density, resulting in huge webpages and high similarity.
Solution: put this part in JS or IFRAME.
4. The title is not enhanced
Question: <B> growing troubles: Full version (Classic dubbing on top) (4dvd9) in the first quarter </B> 337 rows
Solution: Use 5. Some js code in the page
Problem: The JS Code exists in Row 3. By removing bloated and messy code, you can reduce the size of webpage files and speed up webpage loading.
Solution: place the JS Code in the JS file and use the <script language = "JavaScript" type = "text/JavaScript" src = "http://www.dangdang.com/public/webpagetop/js/boot.js"> </SCRIPT> method to call
6. nonstandard use of some labels
Problem: <link href = "*" rel = "stylesheet" type = "text/CSS"/> of row 153 can only be used in the head.
Solution: Move the link to the head label.
7. There are redundant properties in the 287 line Page Link: Target = "_ blank" Title = ""
Problem: The Page code is huge.
Solution: Because <base target = "_ blank"> already exists in the head label of the file, all links on the page will comply with this rule, and the target attribute can be deleted.
8. The image is not optimized in row 332.
Problem: optimizing images will help you rank first in image search.
Solution: website image optimization includes the following:
1. Try to compress the image file size while maintaining the image quality.
2. Alt attributes:
Each image label has the alt attribute, which is read by the search engine to learn about the image information. Therefore, it is best to include a text description in the alt attribute of all illustrations and include the keyword on this page.
3. Add the description text containing keywords above or below the image;
4. Link to the image.
Website link problems
Check the quality and quantity of external links of the website. have you logged on to dmoz?
Dangdang has a good quality and quantity of external links and has added dmoz. Therefore, Dangdang can skip the link issue.
The analysis is complete. It takes more than 20 minutes. Generally, this process takes several hours or even days, because every typical page of the website needs to be accessed, in order to summarize the detailed analysis report, I would like to emphasize that website analysis should be careful and patient.
