If the new web page is not recorded, the external chain will help guide the search for reptile capture and recording.

Different views also welcomed exploration and joint improvement. @jujie
“traditional” is known to users. Please read the full text. Let's start with some bullshit and give you a reason to watch. It's not long, 2,000 words。
I have been a seo since 2004 and have not been transferred, and have been a technical director of a seo company for more than two decades now. The projects that have been carried out include: the travel network, the starting point chinese network, the lv network, the behdo network of cafés, the jiangsu network of watchmen, etc., all signed directly by our company. A little bit of sem, an advertising expert who was officially accredited by google earlier in 2009:

The answer will be based on a combination of practical experience and official search engine files,
As before, there will be definitions in the articles to build a basic consensus on basic concepts that are not rigorous but easy to understand
My common definition of the term "extralink" in the seo job:
Outlink: there's a link on someone else's website to my website。
"extralink" is a popular term, sometimes called "reverse chain" (reverse link); that is, "backlink."Inks or "inbound lInks. We all use the most common term “outlink”。
The first thing is certain:
If my web page has not been captured by the search engine, there's an external link pointing to my unrecorded page, one of the best ways to get the search engine to grab it。
Google and 100 degrees both made a positive reference to the above point on the official web, arguing the following。
Google describes the exterior guide search engine capture:

(exactly: recommend more reading of official documents, more practical experience, less unsupported xx techniques)
A description of the exterior guide search engine capture:

So, does this mean that we can clearly think that the outer chain works
I believe that this conclusion clearly does not satisfy you in front of the screen。
Because your real question is, "does it help to do the extra-chain if i have a more regular website and even a basic seo, and i want to further upgrade my ranking in the search for the target keyword?"
So:
What do you mean, useful? In our exercise in seo, we consider "useful" to mean:
Is it possible to increase the search ranking, page or website weight...
In two, let's talk about google's extra chain
Let's hear about the hands-on hands-on hands-on of seo's colleagues



The main points of view are distilled: google seo stations and content are at the core. High-quality external chains may be useful, but the value for money is extremely low。
Other views (excussions):
1. The question is whether the content of the ai itself is good
2. The ai content, which is less secure, has been successful and more dead。
In addition, in order to be persuasive, the big boss has shown several cases, almost hundreds of thousands. The number of daily visits was tens of thousands。

Let's look at the official external chain saying:

In 2016, andy lipattsev of google publicly stated that the outer chain was one of the three main factors in google's search ranking。
In response to that statement, in 2023, gary illyes of google said at a meeting:
The importance of links has been overestimated for a long time, and the outer chain is no longer one of the three major ranking factors. He went even further and said, “no outside chains can rank”。
Also: john mueller of google said in a podcast called "search off the record":
The outer chain will no longer be an important factor in google ranking
Taking into account the practical experience of peers in the above-mentioned country, as well as the direct expression of google, we can say:
At least from 2023 onwards, the outer chain is still of some use in google seo, but of little use. And the outer chain is not a requirement for seo。
And by the way:
Do you think it's working
And quotes the 100-degree official documents mentioned earlier:

My point is that, starting in 2014, the extra-chain has not been very helpful in increasing the weight of the website and thus obtaining a higher search order。
This view has been expressed repeatedly in other informal settings
Moreover, our company has largely supported this conclusion in its hundreds of project experiences over the last decade。
However, with reference to the document, the 100-degree exterior chain still has the following effects:
1. Lead capture
2. Help guide reptiles to unrecorded web pages
3. In cases where it is not possible to describe keywords on the current page, the extra-link text helps the search engine to judge the relevance of the target web page and keywords. In fact, the inner chain does the same thing
High-quality external chains can still help with rankings (but don't worry, you're registered at the blog forum and in the 100-degree definition of “four links”, not only is it not a “high-quality link” or even a “normal link”, but it's just a “spam link” or a “fake link”
So, with regard to the usefulness of the outer chain to seo, i conclude:
If the new web page is not recorded, the external chain will help guide the search for reptile capture and recording. If you want to raise your ranking through the outer chain, the low-quality outer chain (the link that you can send to register) is not very helpful and is not recommended. If you break it down, google seo, do something if you don't get it right。
