Recently many webmasters will have some questions:

Baidu Update frequency why speed up?

Why does my site have hundreds of pages today and how many pages are left tomorrow?

My collection site why not included?

Too few pages included?

Unstable rankings?

... ...

Of course, Baidu's recent activities are very frequent, we see, as if in one night, these fluctuations are mostly from some new stations (less than half a year of the site), there is no content of the site, collection site (mainly in not included, included number of instability), do not know coincidence also parrot's sake, remember last year's October , we talked about the hottest topic is Google's search ghost phenomenon, because the 07 domestic SEO industry appeared a lot of new people, SEO team slowly in the growing, the industry's view of the SEO is slowly changing, other than that, small and medium-sized enterprises, including some of the portal to the importance of SEO is the best proof, I also have a deep understanding of this, of course, also firsthand experience, previous Newman, Alibaba, Zol and so on have been recruited. I am here to extract some information about the ghost of Google last year, can be compared with the recent phenomenon of Baidu to make a comparison analysis:

Google has two kinds of web crawler, the main reptile and the new crawler. The main crawler is primarily responsible for discovering new Web pages. A webpage will be discovered by the main crawler immediately after the new index is established. If a page is indexed for one months, the page will fail.

The establishment of the new index also requires consideration of other non-questioning determinants. These determinants are related to the level of Web page rankings. To make the most of these pages, rather than wasting time waiting for the next index algorithm to be updated, Google has to take some simple steps to guess the rankings and guess what new content is difficult for visitors to use.

Despite Google's speculation, the following are authentic:

1. The ranking on the Phantom landing page cannot be equated with the index page ranking.

2 The Ghost landing page must be removed from the database before the new database is established every month. However, this is only temporary removal.

If you have such a landing page in your index, your primary goal should be to have the page rank on Google's new page. If you want to do this, you need to periodically, regularly, preferably every day, with a certain interval to update the content of the site.

Why do you want to get a ranking on Google's new page? Because ranking sites on new pages are easier to crawl and indexes easier to update. But the rankings on the new page are not real rankings, and the new page rankings have a strong instability. It takes a while for new page rankings to be translated into real rankings.

... ...

When Google searches for spiders to crawl a new page, what does the new page reflect?

A new page was not charged to the Google home directory until:

1. The Web page was crawled by Google's home directory search spider.

2. After being crawled by Google's home directory search spider, the Web page has to be updated for a period of time.

Only the above two are all satisfied, the new page by the Google home directory is indeed really crawl to the new page rankings can be converted into a real ranking.

Google has two forms of capture

1. Charge

2. New Crawl

A new web page was first crawled by a "new crawl" spider. But there are special cases. After the Google month update has just completed that period of time, a Web page is usually "charge" spiders crawl. Monthly updates are typically between 20th and 28th per month and can last for a few days.

To distinguish between the two spiders, we can look at a set of IP addresses first.

1. "Charge" spider = 216.239.46.*

2. "New Crawl" spider = 64.68.82.*

To further explain the Google Ghost phenomenon of new Web pages, let's assume that the page was first crawled by a "new crawl" spider. "New Crawl" spiders crawl new pages between Google's two-month update. During the master crawl, links to new pages can be crawled. The same is true for new crawls.

Although this page has not been updated and not included in the Google home directory, but after crawling, search spiders began to measure the content and quality of the page, and the page included in the search results. This measure is very unstable, susceptible to external influences and often changed.

These pages fluctuate when the monthly updates come. Regular monthly updates are Google fluctuations. However, you need to remember that the "charge" Spider did not read the page, so the page was not added to the main index. So, when the monthly update is over, the new page is still viewed as a new page but soon after, the "charge" spider will read the new page, which can be included in the main index after the next month's update. It's going to take a while. Prior to this, Google does not show any import links, the page rankings are therefore volatile, unstable.

After reading this information may be inspired by you, from the current situation, not only the existence of Google search Ghost phenomenon, Baidu also has ghosts appear, of course, do stand, do not seriously develop content site is not to worry about this, search engines for all sites are fair, Why some sites start is the same, after six months of development have different search performance, different development? Webmaster should think about it? What have you done?

Sorry to say here, I do personal webmaster also has 5 years of history, Rise and fall, of course, later will be better, there are more members filled more, new station (www.feikebt.com) just started, the total should give a good impression of the search engine, so every time I heard that XXX site is not included, XXX site was K news, I am very heartache, personal webmaster is not easy, especially full-time personal webmaster, art, server, program, promotion, etc. are a person completed, pay so much, if the site is sealed, or included low, domain name down right, this is a very sad thing.

Recently out of the search ghost, Baidu has some new action specifically targeted at the collection site, the new station does not include, included less, or is a collection of large fluctuations and other strange phenomena mostly for the collection station, of course, some illegal site is more difficult to include, the search engine does not wrong, the purpose of the search is to provide users with the best quality search experience, Large-scale collection, without any screening, inevitably have a lot of junk information, duplication of information, no less than the practice of copying sites, so a friend to me to ask for the whole station to download, feel very reluctant, but I will tell friends, you refer to other people's site can, but do not directly upload someone else's content on the finished, It is not so easy to do the station.

Recently also appeared many site group built software? Claiming to replicate dozens of sites in a few minutes, I don't know what the software is worth taking out. Show off, of course, what effect, a lot of seoer may have tried, they also know, at least I saw a lot of stone to see a number of people say that some of the software group built some sites are not included, or collectively down the right. Any time we SEO must understand that we are improving the content of the site, improve the structure of the site, the purpose is to provide more quality search engine content, easier to crawl the site, to bring a better search experience, we can not with the search to dry, so that the site was K, you will have no complaints, first write to this, Above is only my personal understanding, hope to have enlightenment to everybody!

Finally, I wish you webmaster 2008---Hair
