There is an essential difference between Web pages and the weights of web pages.

Search engine contains the page and the weight of the page there is the essence of the difference, that is not included weight, weight is not included.

I used to emphasize the importance of weight, and encourage the site do not lose weight. But there is little mention of the search engine to include more pages, therefore, in this article, the author will discuss this issue from different angles. In fact, there is a very big difference between the weight, from a simple argument that is, the amount of content determines the site in the search results in the frequency and number of times, and the weight of the decision rankings. To give a very simple example, a portal in the IT world will have nearly 500 articles born every day, as they occur, some pages are created automatically, such as tabs, so that the site has nearly 1000 pages of new pages a day, and in these 1000 pages, the search engine contains 500 pages, the record rate is only 50%. The other is a good site, nearly 50 pages a day was born, but 40 records, a record rate of 80%. But in fact, in search engine retrieval results, the front of the IT portal network share a lot, but due to the quality of the next site is very good, and the weight is high, get a good ranking.

What factors are included in the search engine?

Search engine records are regular, the first is to attract spiders, which is also the hardest one. There are shortcuts to attracting spiders, but after attracting spiders, the other thing is to have the search engine index the crawled Web page and add it to its own database. So, what is the impact of this search engine included it?

1. Spider visits and frequency: This is the absolute premise, if the spider does not visit the site, there is no talk about the collection. Of course, spiders visit the site will consume the traffic, and will increase the burden on the server. So, what we should do is let the spider develop the habit of periodically cycling to visit the website, for example, visit the website before sleeping every night, understand what content the website updates.

2. Spider access depth and breadth: Spiders are search engines crawl web information of a robot program, it crawls web information, often have a selection, such as spiders will be based on the depth of the site information to determine the importance of the current page, and to determine whether to include it. At the same time, spiders will also show impatience, when the Web page of which interference information more, such as ads, JS code, etc., spiders will choose to pause crawl.

3. Website or column or even the weight of the page: the weight will affect the inclusion, mainly reflected in the high weight of the Web page will make the spider stay longer, and weaken its selection, will eliminate its impatience. But the weight of the page is accumulated over a long period of time, and to have a reasonable weight planning site.

4. The speed and quality of information generated by the website: the website content written by the authoritative person, such as famous writer, internal engineer of Google, etc., their website update speed is slow, but the record is fast, and more comprehensive.

Although the above is from the search engine perspective, the emphasis on the search engine initiative, rather than the site owner's will for the transfer. Site owners can only obey the search engine, master the rules of the spider, according to the law, perhaps this can get the search engine's pro-Lai.

How to view the collection and weight

Included is the basis of weight, because there is no collection, no amount of weight is meaningless (of course it is impossible). Weight can in turn stimulate the volume, which has already been mentioned above. But here, there is a conceptual misunderstanding need to be clarified: this site refers to the weight and included occasionally will cause readers misunderstanding, especially in the transfer of weight, we often hope that the search engine does not include some pages, or not to pass the weight to some pages. So next, let's take a look at how the collection is generated, how the weight is passed.

Included, as the name implies is to let the Web page is collected into the search engine database, in the process, the search engine will index the information, that is, determine the page and which keywords related. Search engine spiders crawl, first will check the site's robots.txt file, to determine whether the site administrator want to search engines do not include some or all of the pages. In addition to all the pages may be included, as long as the spider can reach this page (in fact, due to some of the above spider characteristics, many pages can not be reached). Therefore, we'd better let the site every page we want to be included can be accessed from the homepage by clicking on the link. And there is a feature is that the number of clicks from the home page, the more opportunities included.

Weight, is the search engine to give a Web page evaluation value, this weight can reflect the importance of the page, the higher the weight, the more search engine to get the trust and recognition, in the rankings to get a better ranking. The key is how to pass the weight. Generally through links, especially with anchor text links (hypertext links, the link text is now counted into the range of weight passed). But the transfer of weight is not the equivalent average, but is passed after calculation. For example, the weight of a page A is 1.00, and it links to 10 pages, the 10 pages will be the sum of 5~6 weight values, they are not completely split the 5~6, but each is different. Some can inherit the weight value of 2, some may only inherit the weight value of 0.5.

It should be emphasized that all links will be passed weights, and weight values will be dispersed to all links. Just as the weight value mentioned above, in this 5~6, if there are 100 links to allocate it, then each link to the score will be very small, even if the weight transmission is not average, but the highest will be lower to 0.01 levels. However, we are not willing to reduce the number of links to make the contributors less, we can use rel= "nofollow" to prevent weight transfer, that is, let these 100 links have 40 links do not pass the weight, then only 60 links to share the weight of this 5~6, although the weight of each page is still very small , but it's better than being smaller.

1. Included and the weight of the misunderstanding that rel= "nofollow" will not be included: In fact it is only responsible for blocking the transfer of weights, and does not prevent the inclusion of links on the page. In order to prevent the link through the chain to receive outbound links, we often will be outside the station to deal with the site of the jump page, with robots.txt block this series of jump page, and ultimately prevent the inclusion of outbound links.

2. Think as long as not included on the weight does not matter: now many sites have a serious problem, is the weight black hole. That is, some of the links in the Web page to a page not included or the weight of the outgoing page. If the weight of a page is passed to a page not included, then these weights are wasted, the weight here into the end. The best is the weight of the site within the continuous flow, and eventually return to the home page or to optimize the target pages.

3. Web jump does not matter: Using meta-refresh, header (), Window.location.href is not sensible, these jump transfer caused weight loss.

In any case, the amount and weight in SEO inside is a pair of very key concepts, on the one hand to fully grasp their important position in SEO, on the other hand, should avoid the damage they caused.
