Life cycle of the outer chain

Absrtact: Any product has a life cycle, whether it is animal or machine, but their life cycle is not the same, and we send out the chain also has a life cycle. The discovery cycle of spiders: for example, you bring a website link to your blog, this time spider

Any product has a life cycle, whether it is animal or machine, but their life cycle is not the same, and we send out the chain also has a life cycle.

Discovery Cycle by Spiders:

For example, you have a website link on the blog, this time the spider will find your link, this cycle can be long and short, perhaps a few minutes can be completed, perhaps 1.2 months, there may be life.

Two. External chain effective Cycle:

When the site outside the link was found by spiders and effectively included, the search engine will be calculated immediately, but the different levels of the chain of validity are different, the chain can be divided into 3 levels:

①. High weight outside the chain: high weight outside the chain can be links, but also can be some more authoritative page links, the high weight of the chain of natural effective time is the fastest, generally 3 days or so can be effective, the search engine will be given weight transfer.

②. Ordinary External links: these links generally refers to the forum outside the chain, blog outside the chain, business-to-business and other Web site content page text links, such as ordinary type of outsourcing links generally effective time is according to search engine update time to calculate, for Baidu is usually 2 weeks update.

③. Outside the chain: simple to explain is the use of software mass and the content of the site does not match the external links, these links for the site keyword ranking basically no effect.

Three. Outer chain death Period:

Different levels of the chain of validity of different, some may be permanent, some may be dead in 1.2 weeks, after the death of the search engine will not be given weight, so we need to stick to the outside chain, or the rankings may fall.

How can we control the chain when we want to rise to the top of the website?

Friendship links are given the highest weight in the chain, but also the longest life cycle, so we need to adhere to do, but to note: The number of fangyou chain is best not more than 30.

Soft outside the chain, soft outside the chain is unlimited, need not adhere to do, but do not eat into a day to become fat, the next day hungry became thin.
