Analysis on the advantages and disadvantages of all-station links

Speaking of the whole station link first we must understand "what is the whole station link", I here on concise say: The whole station link is in a http://www.aliyun.com/zixun/aggregation/10411.html "> website homepage, The content page contains the anchor text hyperlink to a website or the link to the URL, just like the link of the website copyright, if only the homepage shows the URL link of the website, it can only be regarded as a single chain or a friend chain. Seoer website analysis is as follows:

Take my SEO blog, the use of the blog template, the first Friendship link this section code in the home page, categories and content pages have, but I will be the content of the friend chain code removed, leaving only the home page and the category of friends chain display. Because the exchange of friends is not a classification page, so the Friends of the category page chain is equivalent to these stations do a one-way anchor text link. However, I will soon remove the link to the category page, you understand! But this does not belong to the whole station link, after all, does not contain the content page.

In the past, I was in the exchange of friends when the chain, changed to a site-wide link, then I did not know. In the final removal of the link between the two sides, only to see the blog rankings and domain miso rub to decline, analysis of the reason is that the site is the whole station link (home + page), helpless Ah! This is equivalent to suddenly a part of the anchor text outside the chain disappears, can not drop rankings.

But the advantage is obvious, in the period of the blog ranking of the old fast, but also very stable. Disadvantage is not to exchange friends chain, his included pages less good to say, if more
