With the development of search engines, finally remind the webmasters. The exchange of friendship links is no longer a problem. In the future era of search engines, the pr will be more and more biased towards the after wave parameters, and even the day when the friendship links are canceled. Therefore, we must pay attention to the parameters and make early plans.
Ten Google parameter values (defined as parameters for easy understanding)
A BN stands for different sites
This Google parameter is super important. Even if there is no friendship link, as long as the parameter is optimized, the pr value can be improved. This is the qualitative change caused by quantitative change, that is, without setting a friendship link, the pr value can still be increased to 5, rarely SEO This ultimate algorithm is understood by personnel. In this article, I will give a good answer to the subtleties and new changes of Google's pr calculation in 2012.
Analysis 1 of pr calculation formula.
Google's PR calculation method for website links or pages is
PRA=1-d+dPRt1/Ct1+PRt2/Ct2...... PRtn/Ctn+parameters)
D is a fixed constant, and we don't know what this d 0.85 means. That is, 0.85, and PRA is the pr value available to websites. PRt1 exchanges the pr value of websites. Ct1 indicates the number of exported friendship links contained in the website, and so on. The professional term is damping factor (damping factor is actually the coefficient set for calculating PR score. Googl damping factor is generally 0.85RA, which means that from an external link site t1, according to the PR score added to your site by Pagerank? System, Rt1 represents the PR score of the external link site itself; Ct1 indicates the number of external links owned by the external link site. Many SEO experts believe in this basic algorithm and ignore the parameters behind it. If we simply use this basic formula to calculate, we will find a loophole, that is, the PR value obtained by the old website will be high, but the new website will not be able to obtain PR even if it is very popular! Everyone will find three strange phenomena,
1 Some websites have just been launched, and the pr will be updated to 4 within a few days
But pr has been declining. 2 Some websites have more and more links.
Pr is also very high 3 some websites have no friendship links at all.
The parameters of the back wave are ignored, which is the traditional Chinese guess. So search engines will have very complex algorithms to solve. Don't go deep into the algorithm, because you are not a search engine engineer, so it is not more meaningful to study and improve PR. As the saying goes, all changes are inseparable. The website should obtain a high PR value. Friendship links can reach the peak of PR only when they have advantages in both quality and quantity. Similarly, depending on parameters alone, pr can also reach a peak.
Friendly links differ by parameter.
Three factors should be considered when exchanging friend chains:
This is what most people are doing. The higher the 1pr, the better (it is better to let the homepage of a website with high PR value link to your website).
However, the number of exported links is relatively small (many friendship links can't fully understand this, and the 2pr is not too high. But many people understand that the pr is not too high through the calculation formula, but the number of exported links is small or even higher than the pr of the website, but why is the high pr the primary factor? Because the number of exported links is small, the pr of the website is relatively rare)
Or the pages with high parameters of Houlang are ignored by many people who do friendship links. The main pages of 3 authoritative websites. Whether a website is authoritative, the two concepts of website authority and web page authority are different. The authority of a website is formed by high-quality web pages, website reputation, user reputation, etc. When a search engine judges the importance of a page, it may give priority to the authority of the website. Determine the authority of a page based on the authority of the website)
Ten Little Known Houlang Parameters (announced in advance).
Google has increased the time parameter and time factor to drive the pr value, parameter 1. Good news must start
Google's change will change 35% of search results. Google's new algorithm will bring changes to global search results, including Chinese users. Google calls the new algorithm "freshness algorithm". It uses Google's Caffeine web page index system to capture network information more quickly. Google has increased the consideration of time factor in the new algorithm. According to media estimates. The relevant real-time search results are given. therefore Website production The update frequency must be fast.
Add Baidu weight parameter 2 secretly.
Do more and more reasonable, as the search engine leader Baidu weight. The core factor that determines Baidu's weight is the traffic from Baidu, which is basically proportional to your site's inclusion. As Google, Baidu's weight was included in the calculation of pr in 2012 as an important parameter! If Baidu's weight is adjusted, pr will also change
The third is the authoritative parameter of the friendship link website.
For example: backlinks from. edu and. gov
Because neither of these two domains can be registered by ordinary people, they have higher trust. Or your own website authority. As I said before, many people think that search engines give more weight to. edu and. gov domains. Why don't you find an authoritative website with backlinks
The website is included in Parameter 4 by three well-known network directories DMOZYahoo and Looksmart.
The GooglPageRank system attaches great importance to portal network directories such as DMOZYahoo and Looksmart, especially the DMOZ link on a DMOZ website. For GooglPageRank, it is well-known. It is as valuable as a piece of gold. If your website is included in ODP, it can effectively improve your page level. It is not difficult to submit your site to ODP and include it. It just takes a little more time to ensure that your site provides good content, then click "Add Site" under the appropriate directory of ODP and follow the prompts step by step. At least ensure that your index page (INDEXPA GE) is included. Therefore, if your website content involves several completely different pieces of content, you can submit each content page to ODP separately - but please remember that "more haste, less speed". After Googl updates its directory, you can see what the PR value will change. If your website is included by Yahoo and Looksmart, your PR value will be significantly improved. If your website is non-commercial or almost completely non-commercial, you can make your website included in the famous online directory Looksmart through zeall.com. Looksmart also gets non-commercial search lists from the Zeal web directory. Before submitting your website to Zeal.com, you need to pass a small membership test. Don't worry, this test is very simple. If you are a webmaster, and your website has been included in the three well-known open directories DMOZYahoo and Looksmart, guess that your website's PR value must be high, and your search ranking will not be poor.
Pr correlation is also an important parameter, parameter 5. The content relevance of the corresponding web page. Why do I first introduce how to make websites relevant, that is, the local algorithm of text content matching: when searching for keywords of websites, Googl will give higher weight to the keywords appearing in the meta titl. So you should ensure that the title tag of the website contains the most important keywords, that is, you should determine the content of the page title around your most important keywords. However, the title of a web page should not be too long, generally between 3540 characters. As we all know, Googl does not use meta tags (MetaTags such as keywords or description tags). This is because the text used in these meta tags cannot be seen by actual visitors, and Googl believes that these meta tags will be used by some webmasters to fraudulently place some popular keywords unrelated to their websites, so as to improve the ranking of their websites on the irrelevant keywords, thus gaining more visitors by improper means.
It means that Googl will generate a description of a website from the first few lines of text of a webpage. In other words, MetaTag feature is not supported. You'd better put your keywords or key phrases at the top of the page, so if Googl finds them, you will improve the relevance of your website accordingly. Once Googl can't find such relevant content, you need to spend a lot of effort to make other parts of your page relevant. When determining the relevance of a website, Googl will also consider the keyword density of the body content of the page KeywordDensiti, so you should ensure that there are several keywords and key phrases throughout the entire page. But remember "too much is too little" 6-10%
The keyword density is the best.
The keywords appearing in the content should be bold as far as possible. Googl now also indexes the ALT attribute text of the image and counts it in the correlation calculation. Therefore, keywords should be included in the ALT attribute. Other strategies to increase page relevance include: putting keywords in the title content. To increase the relevance score of the website.
It is also mentioned that the external links of the website will be analyzed and included in the relevance when calculating the page level.) The last skill to increase the page relevance is to make the external text links on your website contain your keywords. Including keywords in external text links can effectively improve your website relevance score (in the description of Googl's PageRank technology).
The corresponding text link content has been provided. For example, welcome to the friendship link. How many keywords should be included in the text link? This is a question of different opinions. However, I noticed that there are many websites in the link exchange area. Please use the following code to establish a link to this website.
The number of external links and quality parameters of the website are six.
Of course, the management of domestic forums is quite strict now, which means that many people go to some high PR forums or blogs to post or reply. When you want to post or reply, it is easy for the administrator to delete the out of band link, so you must be patient to find more such forums and then test whether you can post (reply to) the out of band link, not only for the sake of the out of band link, but also for the sake of pr~
PageRank will take the number of external links of the website into account. It can be said that the more external links a website has, the higher its PR value will be; The higher the level of the external link site (if Macromedia website links to the website), the higher the PR value of the website. When calculating website rankings.
The higher the number of external links of a website (the more votes you get), the more important the website is. So when you search with related keywords, you will get a higher ranking? absolutely wrong.
There is only one thing left for all webmasters to exchange links crazily. Googl's emphasis on the number of external links on a website does not mean that you can establish a connection with any website without seeking strategies. This is because Googl does not simply calculate the number of external links on a website to determine its level. In that case. Get as many external links as possible. Googl's description of Googl is not just about the number of votes on a website, or the number of external links on the website. At the same time, it will also analyze the websites that voted. If the PR value of these websites is relatively high (of considerable importance), the websites they vote on can benefit from it (also of great importance)
Not that for a website, then. The more external links with higher website quality and higher PR score, the better? Not necessarily.
The number will also be considered. For example, it is wrong because the GooglPagerank system does not only consider the external link quality of a website. For a website X with a certain PR value, if your website Y has only one external link, Googl believes that website X regards your website Y as its best external link, which will give your website Y more points. However, if website X already has 49 external links, Googl believes that website X only regards your website as its 50th good website. Therefore, the more external links on your external link site, the lower the PR score you can get.
Originality of content (this explains many cases where websites have no friendly links but high pr) Parameter 7.
Increase the citation of web pages by allowing people to reprint or send in groups. Create more content to enrich your website page; Write more high-quality articles.
Parameter 8. Number of pages captured by Googl website Number of pages included)
The more the number is, the more pages the Googl website grabs. The higher the PageRank value. But usually Googl doesn't take the initiative to grab all your pages, especially if there are "? Dynamic links in the website. Googl doesn't take the initiative, so the most stupid way for me to take the initiative is to submit all the pages of the website to Googl. But I don't think anyone would really do that, but there are few words on the page to try. A better way is to create a static Html page, which is usually called" website map " Or "Website navigation" includes all the websites you want to add, and then submit this static page to Googl
Number of export links
Powerful pr tricks (sprocket, parameter 9, Google toolbar, etc.)
More improved pr is also useful Google toolbar here will no longer put forward sprocket is not only applicable to external chain.
PR chain out
However, due to the damping coefficient, YPR is effectively transmitted to the sprocket when PR is chained in. PR shows gradual attenuation. But when the PR chain of the sprocket goes out to Page Y, the original PR and attenuated PR are effectively transmitted, and the page YPR is improved to the maximum extent.
The following figure shows the maximum acquisition of PRMA X. It is also the basic prototype of sprocket.
Basic prototype of sprocket
The PR of A BCD page is transferred to Y once, and the PR attenuation in its sprocket is also transferred to the page Y page Y one by one to obtain the maximum PR value.
Strictly punish cheating (temporary dead links such as unstable servers punish behaviors that do not respect intellectual property rights) parameter 10.
Google has put up the original conservative PR value evaluation rules, in order to adhere to the fairness and justice of website evaluation. The new evaluation rules have been activated. The most prominent feature of the new evaluation rules is that the "base value+variable value" base value is related to the comprehensive evaluation of websites, and the variable value is related to the external links of websites. However, the base value plays a leading role, which endows high weight websites with greater evaluation rights, It has effectively cracked down on cheating or excessive SEO optimization to get a good ranking for a keyword, ensuring that the content users need to find has a good search ranking.
Fifth, case description.
One station has two friendship link stations, for example. And they are all pr2 websites, and the exported links are my website, so the pr value that my website can obtain is PRA=1-d+d2/1+2/1=1-0.85+0.852+2=0.15+0.85 * 4=0.15+3.4=3.55 Suppose that my website is linked to a website with a PR value of 4, and the number of external links is 10, then the calculation formula is as follows:
If my website gets a link with a PR value of 4 and 10 external links, PRAKA=1-0.85+0.85 * 4/10=0.15+0.85 * 0.4=0.15+0.34=0.49, that is to say. Finally, my website will get a PR score of=0.49. Let me see if my website gets a PR score of 8, and the number of external links is 32, then my PR score will be PRAKA=1-0.85+0.85 * 8/32=0.15+0.85 * 0.25=0.3625.
