404 can the error be solved by 301 redirection?

I readanarticle on"use 301 redirect 404 error into thewebsitechain" article about how to redirect the way through 301, willget the error from the external URL into accessible URL, so asto transfer the weight of articles.

Today in A5 saw a "talk about the use of 301 redirects will betransferred to the 404 page of their own chain of harm", refutemy previous article in the view. I think that' s very good. TheSEO industry should have the spirit of questioning and theability to think independently.

Read the article, the author found that misunderstood me. So,write anarticle to clarify the point of view, and to introducethe role of 301 redirection.

First of all, I make clear the two ideas in the article "using301 redirection to turn 404 errors into the chain outside thewebsite":

The article is about the 404 error URL, through the 301 redirectback to the original URL. This needs to be explained. I didn'tmention any 301 to the front page or any other page in thearticle

The example of this article is about the behavior of URL errors,spelling, linking, adding errors, and intentionally generating

error URL in the process of entering A websites from external(B) websites. It' s not the 404 mistake that the A site itselfhas

The original is always there, and friends who have doubts canread it carefully. Now let me back up with this friend' s pointof view:

Refute the first paragraph

The original author, the 404 error resolution points to thechain in the site and the external cause, this sentence but the404 error no ground for blame, and it is also because of theirown website program, since there is no way to escape, such asin the A5 page can also appear a lot so alive that suffix the404 page, directlybehind the accession to the 1.html, 2.html,can, That' s all. , but if someone deliberately plan with the formof the chain link to this page, that is to bring the link,website That' s all. , top produced a 404 page, and there willbe no other.

There are 404 errors in the website, which is not necessarilythe internal procedure of the website. Spiders crawling throughexternal websites (B sites) , a wrong URL crawling to their ownwebsites (taking the A site as an example) , also cause 404errors, that is, the wrong URL leads to the wrong page.Spiders don't care if you link URL to the inside or outside ofthe website, and as long as there' s a page that doesn't existwhile crawling along the URL, you' ll record a 404 error.

This is clearly visible inthe Google AdministratorTool' s "runstatus"-"scratch error"-"can' t find". 404 errors are dividedinto two items: "in sitemap" (internal cause) and "link to theweb page of your website" (external cause) of the item "".As the name suggests, the "link to your web page domain"refersto the URL link from the B site to the A site.

Refute the second paragraph

And the meaning of the original author is how to grasp the weighton the one hand, to this weight of the chain directly back, andnot let go, here, I also have my own point of view, this is thechain itself "http://www.xxxxx. com/rich-snippets.htmlGFQ",the chain link is over 404 pages, if you put these pages 301off, this situation and website appeared in a large number of404 pages, and then directly to the 404 page 301 to a page isthe same; if your site has 404 pages, so in order to preventthe loss of weight, it will all these pages to the home page301? This is not completely consistent with the search enginethe requirements, if you want to know about it, just use BaiduSearch "404 page 301 to page can understand more harm".First of all, there is a clear distinction between the searchengine and the "behavior" or "external behavior". Take linkconstruction, the internal chain and the chain in the weightof the effect is different.

Everybody knows that. The core idea is that the chain is thewebmaster can't control, and the inside chain is the webmastercan set up. Although in the search engine development process,

appears "can be controlled by the webmaster outside the chain"this factor (is the usual outside chain construction) . Butwhether or not the controllable controllable, there is apremise that the idea is clear, who would not be able to releasethe correct URL in someone else' s website, but to send the wrongURL, causing the user can not access your own website or "onhis website, the page does not exist".

Secondly, for 301 to the original page, or 301 to the front page.I don't want to say more about it. Everyone can understand whatI mean. What I'm going to talk about here is some of the signalsthat the search engine is trying to identify the source of thesource text:

Where does the search engine first see content?

Trust in domain names that share the same content

Where is the link to the most (the inner chain in the text)?Does the copy linkback to the original source (copyright link)?Because of the existence of second signals, our originalauthors have published or reprinted content on other websites,which can not get a good ranking. Many authors also complainabout this. But we can use the 1, 3, and 4 signals to correctthis error.

Baidu in this respect is not very good, but Google can quicklyand accurately identify the original source. This is due to theabove 3 items. The "copy is link back to the original source

of this factor, I also use 301 redirect in" 404 mistakes intoone of the purposes of this site outside the chain "in thisarticle, there is a goal we can see is the transfer of weight.Finally, the error URL that a user can' t access is reasonablyredirected to the correct URL by 301. It also helps the userexperience. We also saw this sentence in the Google

Administrator Tool' s "scratch error".

Googlebot cannot grab the URL because it does not exist at thepoint. In general, 404 does not affect your site' s ranking insearch results, but you can use it to improve user experience.The solution to the 404 error is nothing more than a robots.txtshield, or301 redirection. I don' t think shieldingcan improvethe user experience. Robots. txt can only improve spiderexperience. Because the user clicks on the wrong URL, itaccesses a page that doesn't exist and sees 404 errors.Refute the third paragraph

If you want to return a code other than 404 or 410, or redirectthe user to the home page and other pages, instead of returning404, you might have a problem. First of all, it means that thesearch engine can find the actual web page through the web site.As a result, the search engine may grab the URL and index itscontent. Because the Googlebot does not exist to use a lot oftime ", may not be able to quickly find your URL or frequentlyvisit these URLs, can frequently visit these URLs, thusaffecting the capture amount on your website (in addition, youmust also do not want their own websites often appear in the

[file] did not find the search query) . " This is the 404 pageof the original words, if you do not continue in accordance withthe requirements of error page Jump, the same page, theemergence of a large number of possible scenarios is yourwebsite on the same title, the same description, the samecontent, and so on, then it is different between the URL andthe same content of the story, as for the future what is this?You can go to Baidu, its own Google to find that.

Since the friend who has refuted mentioned the Googleadministrator' s guide, don't forget to extract anotherparagraph:

Generally speaking, 404 errors will not affect the ranking ofyour website in Google, so you can safely ignore these errors.This error is usually due to the following reasons: spellingerrors, configuration errors (e.g. link by a content managementsystem automatically generated) or Google to strengthen therecognition and grasping Javascript embedded content link inthe efforts.

To view the source of invalid links, click the url. In the errordialog box, click the link from the following page tag. If therelated links are from your website, please repair or deletethese links. If these links come from an external site, you canuse these data to improve the user experience of the site. Forexample, if someone is trying to link to your website and losethe wrong URL, there will be a legitimate URL with spellingerrors. You can redirect the wrong URL 301 to the correct URLand get the expected traffic through this link instead of

returning the 404 error. You can also make sure you help themfind what they want when you direct the user to the 404 page,instead of just showing "404 is not found. "". However, we onlyrecommend that you take the above measures when the error linkcan generate higher traffic.

Unfortunately, the friend saw only one of them, but did not seethe other. When we do SEO, the official data is very important,many details are hidden in it, it takes a lot of time to readand understand carefully.

In fact, a lot of settings and descriptions in Googleadministrator tools make sense. It' s just some of us who don'twant to understand SEO. Just like the internal and externalcauses produced by 404, there is also a reason to separate itfrom a "grab mistake". Instead of doing nothing, just do it.Sum up: as SEO, we should absorb a lot of knowledge, at the sametime open up our own thinking and analysis of the problem. Butyou need to make sure that the knowledge you learn is advancedrather than obsolete. Otherwise, your ideas can easily bemisled, resulting in bad results.

The debate about ideas is also a very important part of SEO' swork. No one can say for sure that his understanding is correct.We can onlyprove the correctness of our ideas and theories withsome official information and the conclusions drawn from thedata analysis.
