A brief analysis of the duplicate content of the invisible killer of website weight

We all know that the website revision, with the IP site problems, or their own site is attacked and so will let their site down the right, but there is also a factor will affect the weight of the site, that is the site's duplicate content, the site if flooded with more repeated content will inevitably affect the weight of the site and ranking, So do a good job in this respect is a good SEO important move.

　What can happen to duplicate content?

1 acquisition content. This is easy for everyone to understand, many webmaster in order to save the time to write content, go to other sites to collect some content to fill their own site, this will certainly result in duplication between the content of the site increase, and for the consequences of doing so we are aware, but there are a lot of stationmaster exist lucky Psychology, However, the author suggested that we can be appropriate false original, in the article to add their own understanding, the total than direct copy paste, more let spiders like.

2 duplicate content caused by API site. This reason is mainly for Taobao guest site, because the API site in the update will produce a lot of duplicate content, these content has the trend of homogenization, but now we do not worry, because Taobao has banned the use of Taobao website API promotion.

The 3 sorting function results in a repetitive rendering of content. Like some large-scale shopping navigation website, on the homepage will appear "by the sales Rank", "according to the heat rank" and so on column, these different sorts are generally based on the URL dynamic parameters on the completion, imagine a hot product is likely to be high sales of products, so this creates a different URL combination, Such a product once more, for the website optimization is quite unfavorable, because will produce many 22 cross URL address.

4 on the 3rd I said a lot like novels, download the site will be the same quality of the content of the trend, in fact, for the electrical business of the industry this situation is also many see, perhaps you will say that the content of the electric business site is very small, more pictures, it is unlikely that this situation, however, is precisely the reason for the image of the site Because we all know that spiders don't recognize pictures, at this time, we will use the ALT tag to label the picture, but this does not guarantee the reduction of duplicate pages included, because the ALT tag is marked less text, large pictures of the URL address is still the same, so it is still difficult to avoid the site to repeat the collection of pages.

5 Web Site program settings problem, site in the process of construction, sometimes webmaster relative to the site to achieve a preview of the effect of their own in the background to create a part of the dynamic page, but because these dynamic pages are ignored, so spiders in the crawling directory will still be included, carefree matter caused the site to repeat the appearance of content.

6 RSS Subscriptions generated. About RSS Subscriptions Everyone is familiar with, for some large news sites or personal blogs and other sites will use RSS subscriptions to generate the content of personal sites, but the content of these personal sites will be reproduced by others, which will cause the original source information and other content of the site overlap, the spider repeatedly included also become possible.

7 The duplicate page caused by the error code. We all know that the error page return code can only be 404 status codes, other status codes are wrong, for example, if you are using the status Code 200, then you delete a page, you will tell the spider on the other side of the page's request to succeed, this will result in the content of the site again included, the same truth, If you want to guide the error page, you must use the 404 status Code, otherwise it will cause duplicate content of the site.

　　Repeat content in the spider seems to be a kind of cheating behavior, so the site repeated high words will cause the site weight drop, then we in the common website construction and maintenance should how to prevent it?

1 to reduce the frequency of collecting content, this is easy to understand, there is no unearned things, if the development of the site to rely on acquisition, then the site will not continue to survive the hope.

2 Each page is accompanied by a unique title. This is a very important place, because the label is an important part of the site optimization, it can be added to the spider to distinguish the uniqueness of the page, for the user experience is also a good improvement, especially the column page, a unique label can make the internal page weight to get some optimization advantages.

3 Modify META tags. A good description of the spider's collection of judgments plays a significant role, but now many sites are using CMS programs, regardless of large-scale implementation of META tags independent, so the author suggested that you manually modify a part of the META tags, at least more than the total number of pages share a description of the effect is much better, Of course, this is also helpless.

4 for the article to modify, False original. It's difficult to get people to collect articles. This I can understand, after all, have done the site webmaster know, every day to write a certain article, even if their own is a literary writer, but also can't carry every day to write, but for the collection of articles, we must make changes, preferably with their own words again, In the middle of the article to add their own opinions and understanding, which is a flattering way for spiders.

5 Modify the CSS style sheet. Many novice stationmaster in order to reduce oneself to build the website difficulty, sometimes will go to download someone else's Web site or content page, and then slightly modified to put on their own site, but the novice webmaster don't forget, download the sample page has many similar CSS style sheet, if not modified will make the website repeat degree rise , of course, personally, I do not agree with you to imitate other people's Web pages, modify style sheet, after all, do the site to have their own characteristics.

6 reduce invalid or duplicate URLs. In our construction process from the beginning of the site as far as possible to make the URL unified, do not use dynamic page to connect, because the spider's point of view, it is not like dynamic page.

7 reduce the link between invalid content. Many times we will be on the previous site structure or content page to modify, virtually will leave a part of the deleted content, for these things we need to clean up in time, using the Administrator tool to remove these invalid links, lest spiders repeat crawl, so as to form a situation similar to the status Code 200.

Website construction is like the human body, any one aspect of the omission may cause "disease", so when the site appears down the right or ranking down, do not always think is the friend chain, Web site revision, and so on, there may be duplication of content caused, for this point we can not be complacent, in the short term may not see the bad, but over time, The stability of the website development can not be guaranteed.
