For What Are The Redirects And What Help Web Positioning
August 22, 2013 § Leave a comment
The 301 redirect and canonical domains are options that have been used for a long time, but today, both can be a complex issue because it raises doubts and confusion, not knowing properly used within a web strategy.
This article will discuss both options to see which is the best way to avoid duplicate content, keeping the positioning and improving the user browsing experience.
For what are the redirects
Although there are many gaps in the information provided by Google, there are some guidelines which can guide us when creating a redirect or a subdomain. In simple terms, you’re options are used to:
301 – Indicates a search engine to our website and is not in that domain and has moved to a new site. This will provide the basis to to be removed from their index and index the new page.
Subdomains: Used to notify the search engines that we have different versions of our site. So, the search engine will know what our main sections want to stay within your index and which not.
Code 301 used in HTTP, is used to make a permanent shift from one location to another. When using this command, transfer authority is achieved, the relevance and ranking of a page to another.
Redirects also serve to inform users and the search engines that are still relevant content into our new site.
There are some common problems that arise when using the 301 redirect.
One of the main obstacles to using this command is that it may not be possible to modify the code http, may be due to lack of access to FTP, the web designers contraindicated or not has the access to server. In any of these three cases, make use of the 301 will not be a viable option.
Another drawback is the time it takes the search engines move all the authority he had his old domain to the new. This will depend on how often you update your new page, and the time it takes the motor to re-index your site. Therefore, it is not recommended to use a 301 when you want short-term results in a positioning campaign.
When we use the 301 redirect
- In pages that are moved or replaced permanently.
- In domains that have moved completely as acquisitions,
- When there is a 404 or the content of a section has expired.
The attribute = “canonical” rel
The rel = “canonical”, though often used as a substitute for 301 redirect is a command that has a completely different use. Instruction rather than redirect users to a page with the most recent or most relevant, is an indication that is intended only for the search engines.
Sometimes, however hard they avoid, creating sections within sites similar or identical content. In this type of situation is when we use the rel = “canonical” so we can tell the search engines that it is avoid duplicate content penalties.
For a better understanding of the case, consider this example: suppose you have two sections with different URL but with the same list of items in a list is organized alphabetically, while the other products are for prices. If you need both pages, you must tell Google (via the rel = “canonical), which is the most important, in this way and show the indexed within the search results.
Following the previous example, if we put the rel = “canonical” on the page with the products in alphabetical order, we would be giving the search engine understand that we understand the duplicity of content and interests us more authority to the section with the list of Prices.
Either way you should take into account that by using the rel = “canonical” or 301 redirect will lose a little PageRank in the new domain.
Common problems rel = “canonical”
As with the 301 redirect, there are some limitations when using the rel = “canonical.
Using rel = canonical “does not guarantee that the search engines will follow it to the letter. In some cases (in the search results) are shown well before duplicate content pages that wish positioning sections.
Another problem that occurs with the rel = “canonical” is when implemented incorrectly. Sometimes the label is used for differences two sections that have little percentage of duplicate content. This should not happen, the rel = “canonical should be used only when the contents of two pages is similar in a high percentage.
When we use the rel = “canonical”
- When the 301 is not feasible to use, or where to take us a long time to implement.
- In case of duplicate content and you want to keep both sections.
- By having dynamic pages that include different URLs to other subsections.
- If you have two domains in which the sites are similar and both must be kept “alive”.
