What's an external and internal connection
Seo is the search engine optimized, the web site optimized and the external chain 360 optimized。
Intra-chain optimization is the interconnectivity of pages within the website, with a more rational web link structure, which increases the capture and weight of the search engine and does not significantly optimize the overall traffic of the site. Read this in detail to add an internal link between the first page and the useful page。

The outer links are external links to the website and are intended to increase the overall weight of the site. The outer chain may not be a friendship link, but choose a website with a slightly higher weight. And this is a soft text that can be posted first in a blog with links to its website
What about the external link to the foreign trade website google seo
The search teacher told me that the external link to the foreign trade website google seo began to grow once the search engine's new page reached 100 pages, and if it was not less than 100 pages before, it would have made the search engine look like you were cheating, and that it would have been about 30 extra-links in the morning to build the site, and that it would have been able to upgrade the extra-chain with the steady increase in the time it was recorded, and it would have to last for almost three months, and then you would have found that the extra-link was well built

It's really very important that the links can be broken down into black chains and white chains, of course, which are cheap, which are expensive, and that the ones that are exchanged are normal, and that the authors suggest that you all do not do it, especially in relation to foreign trade websites, and then this one can do a little white chain, collect it in general, though mostly similar sites
How does seo make the outer chain
Four elements of outer chain construction
We understand the outer chain, and maybe you're not a complete seo, but from the link, the search engine can be a good measure of the number of links to the target website and the level of authority, and further judge that the target page is targeted at the particular target keyword and is a reasonable location in the search results。
At the same time, it is an important medium for your constant updating of your 100-degree algorithms, so that, in many seo skills, the construction of extra-chain resources still plays a positive role。
The four elements of outer-chain construction: relevance, record-taking, authority, stability, let's analyze one。
Relevance
There's no relevant outer chains, not good ones。
You find a bunch of links to your website that can only be identified as a “spam link” or a “free link” that is at the core of the outer chain。
Relevance and: the subject of the location of the web page is relevant to the subject of the web link, the title is relevant to the text, and the anchor text is relevant to the text。
For example, the extra-forum link for travelling to the guangzhou hospital must be hospital-related, the heading of the outer-chain article must be hospital-related, and the section of the outer-chain search that is part of the external link is related to the guangzhou hospital。
The above three articles have a decisive impact on the functioning of rankings, which, if not impossible to achieve, must at least guarantee an absolute 100 per cent correlation between the title of the article, the content of the article and the link to the anchor text。
The search engine speculates whether an outer chain is of good quality and more than 80 per cent of the factors are correlation and the core of the outer chain。
New intake rate
Relevance determines how the link is determined to be of high quality, and the new intake rate determines whether the link works。
I'm still a press release, a forum, a front page of the ppr. Only if it is captured by a search engine will the search engine judge directly that the link has the right to vote. If none of the web pages that link you are recorded at 100 degrees, then the web page itself is simply unable to convey the weight of the message and enhance the ranking。
The intake rate of articles must be checked in person or randomly on a daily basis, and work is being carried out on a daily basis. Analyse pages that are not captured by the search engine, document and analyse reasons, improvements and adjust strategies。
Authority
In general terms, authority often refers to sites that have some influence in the relevant industry, as in the case of seo:
One is full of individual blogs by consulting industry experts。
2. Associations of relevant trades, including social research groups。
A5 of the legendary seo industry。
Those sites, more like the seed sites mentioned above, are not possible if the pages are more relevant。
Stability
Stability is in addition to the removal rates and the frequency of new chains that have passed through previous chains。
The sudden addition of 100,000 extra-chains a month ago, and the sudden transformation of them into 10 after a month, not only means that the past results will not be valid, but will then result in ranking and full punishment of the website. In order to stabilize the outer chain, once the outer chain is volatile again, the search is for anchor text, extra-chain articles, off-link websites, registration numbers, etc。
New additions to the outer chain mean that for a certain period of time in the future, for example, one year, each day and week, there will be a detailed plan: an increase in the number relative to the smoothing of the outer chain, or a decrease in the number of smoothing of the outer chain. For example, the keywords are very well ranked, and at this point we want to reduce the outer chain, so we don't stop at once, and we suggest that you increase every month
