There may be problems with SEO for several types of reasons: content, structure, and links. Most people understand the importance of doing content and linking, but there are many bigger but less built stations that suffer from some very basic problems, such as the URL structure. Such a basic problem can lead to more pitfalls, such as duplicate content issues.
Here are three of the most common URL problems found on different Web sites. If your station takes you to have a even more such problem, look at the solution and fix it ASAP.
Issue 1: web site without www and www version of URLs
If all URLs of your site have "no www" and "www" Two versions, the link value of the same content will be split by two URLs. This way you're not going to get the search rankings you want with the 100% link value, but it will become 50/50,60/40 or other split points.
Remedies:
1, decide which version you want to use the URL, "have www" or "no www."
2, give you do not decide to use the URL to do 301 redirect to the corresponding another. This will not result in loss of link value being split.
3, in Google Webmaster Tools set You more determined to choose domain, so you appear in the search results list and the results will be consistent with the URL you choose.
4, to determine whenever the site to create a link, be sure to use the same style of selection of the URL.
Question 2: Repeat homepage URLs
This situation is somewhat similar to the first, but it is worse because it appears on the home page.
It is highly possible to have many different URLs on the home page, especially if you do not solve the recurring problem of "www" and "no www", there will be more unnecessary duplicate URLs. For example:
Http://www.mysite.com
Http://mysite.com
Http://www.mysite.com/index.html
Http://mysite.com/index.html
These URLs all point to the same content. Although many websites have solved the problem of "have www" and "no www" Two versions of URLs, they can still see many different home URLs. I have seen the URL of a site with different extensions (. php,. html,.htm, ect.) for the same page. This will lead to more content duplication and potential risk of link value waste.
Remedies
1, similar to the first case, the following are some tips:
2, the homepage URL set to http://www.mysite.com. Redirect all other 301 to this most basic URL. (If you prefer "no www", use http://mysite.com)
3. If you have to set up a different version of the link for some special tracking purposes, set canonical tag to let the search engine know which URL you want to display in the search results.
4. Make sure that you link to the correct version when you create a link to the home page.
Issue 3: Dynamic URLs
Funny thing is that a lot of SEO is not so friendly to the shopping cart is such a situation. Once you have included the URL in a variety of variables and parameters, then duplicate content and waste link value of the situation can be said to be endless.
Look at the following situation, all URLs may point to the same content:
Http://www.mysite.com/somepage.html? Param1=abc
Http://www.mysite.com/somepage.html? Param1=abc&dest=goog
Http://www.mysite.com/somepage.html? param1=abc&dest=goog&camp=111
Http://www.mysite.com/somepage.html? param1=abc&dest=goog&camp=111&id=423
So what if we adjust the parameters now? The same content will be displayed. Yes, as you can imagine, a lot of link value is wasted.
There is another reason for dynamic URL problems. Many companies use a URL with parameters in order to be counted. But be sure to make sure from the SEO point of view you are not a self-inflicted trap.
This issue also appears in the site to its affiliate with a separate ID using its link. You can have 100 alliances linking to the same page, but all URLs can be different because each federation has its own unique ID.
Remedies
1, if possible to determine your site you use the SEO-friendly URL. Having a base URL to content is much better than a URL that relies on parameters. Like http://www.mysite.com/unique-product.html than http://www.mysite.com/category.php? Prod=123 will be good.
2, set canonical tag told the search engine to use the basic version of the URL. So you can still use the URL with the parameter, such as http://www.mysite.com/unique-product.html? param1=123¶m2=423 to collect statistical data, but search engines will think that the base version is the official address.
3. A better way to solve this problem is to get the data from the server side and redirect the visitor to the correct URL after obtaining the data. Many alliance networks do this. Access will follow this route: The visitor clicks the URL with the parameter-the visitor hits the site, the server logs the parameter data and redirects it to the correct landing page-the visitor will not notice the jump, because it is fast. This allows you to get the data you want, as well as ensure that all link values are delivered to the correct page, and visitors can see what they want to see. One arrow and three eagles.
What's wrong with your website?
Problems with URLs may be worse compounded. For example, you may have problems with the "no www" and "www" two versions, as well as dynamic URLs.
Check the site carefully to see if you have the above mentioned situation. If so, fix it as soon as possible. Only if this problem is solved well, your link building work will be of greater value.
