Friendship Link Exchange and PR value analysis

A: determine the number of outgoing links:

Generally, a page is kept below 12. This is mainly a commitment to your linked partners. High-quality websites are not interested in websites with dozens of outgoing links on a single page. They also provide a precondition for your website to be linked to a high-PR website.

B: optimize the internal structure of the website:

Allows search engines to include more pages on your website. For example, clear the website structure, clear the classification, and clear at a glance; establish a navigation bar to directly link to each subcategory; create a complete website map, when you add a page, do not forget to update the website map page. Make a link to an important page on multiple pages of the website, this is also why the PR of the homepage is generally higher than that of other pages. (I will discuss this in detail in the next article)

(2) factors that affect the prvalue (of course only part of this ):

A: The number of external links and the quality of external links (PR and number of outbound links of the link) are well known.

B: Google includes the number of pages of a website (I think it is a key factor)

(3) thoughts on PR updates:

Since the PR value mainly depends on the number of entries in the same link and the number of pages included, we need to adjust the website accordingly based on these two factors.

C: We should be very careful when linking. We should never put links in low-quality self-help links (or most people call them linked farms). This will not only help increase PR, it is very likely that you will be punished accordingly.

D: In the face of self-help links, you should first check the quality of the website, followed by the quality of these outgoing links, and whether there are multiple external links in a domain name. If yes, it proves that this self-help link has not passed any approval and is extremely dangerous! There are many self-help links similar to directories, which is the first choice, because the website owner will submit the website through a request, which is a guarantee for you.

E: some strategies for exchanging links:

1. Website rankings (refer to popular keywords). Such a website will not only bring a certain amount of traffic to your website, but also be a good partner. Because only websites with high quality can be put in the first few places for a long time (generally a month is already a good website ).

2. Check whether the linked website has been indexed by major search engines and how often it is updated by the search engine. (the last updated time of divisor is displayed in the search results, if the link is not updated for more than three days, it will not be displayed.) if the linked website is indexed by various search engines and frequently updated, so your website will also take up a lot of light. Because the search engine also updates the linked sites, you do not need to pay for the updates (such as "Baidu") to the search engine company ")

3. Whether the website contains most pages. If a website has good quality and reasonable structure, such a website is favored by search engines. The number of webpage records is proportional to the PR value. Of course, some websites include more than 2000 pages, while some include more than 80 pages. The latter must be poor. We can see that only the proportion is included, not the number. If the former has hundreds of thousands of pages for more than 100,000 pages, this is not a very good website, and the latter has more than 80 entries for only 2000 pages. Obviously, the quality of the latter is much higher than that of the former. Such a website is also an ideal exchange object.

4. Whether the website is indexed by a large classified directory (such as dmozyahoo); low PR is only a temporary task. It will take a longer time in a month, people's PR will fly, and then you will exchange with others, people may not agree, all have to have a long-term vision to treat the current thing) 5. What is the quality of the website; this is related to the long-term existence of the website. If the quality of the website is poor, but the PR is very high. Such websites are not ideal exchange objects. The PR of websites with poor website quality will be downgraded one day, which adds a huge factor to the instability of PR.

5. Have you exchanged links with many similar websites or with many websites (excluding self-help links)? This is also a potential factor for increasing PR, during the exchange, you can check the number of links of the other party. In particular, there are not many links with high quality.

6. Is it a similar website? Because in the ranking algorithm, similar websites vote for your website with a higher score. In this way, your website may have a better ranking.

7. Try to submit data to a large category directory. This method not only gets high-quality reverse links, but also does not have to pay any price.

F: the relevance of linked websites is particularly important. In general, when exchanging links, you should consider not only the quality of the other websites, but also the relevance. If the website is not related, the ranking and PR of your website will not be significantly affected. Therefore, it is recommended that you select a highly relevant link as the homepage link when switching links, instead of the secondary page link for the relevant websites even if PR is higher.

(1) data collection time before PR update:

The grasp of this time cannot be very accurate, but it is only a rough speculation, but there is still a realistic basis. From my observations on my personal and company websites, I got a deadline for data collection before PR updates, probably around mid-December February. according to (you can also speculate on your website): among my multiple websites, there are multiple secondary pages with PR 0. The vast majority of these pages whose PR is 0 were uploaded or created after December 31, middle February. This helps to prove the deadline for data collection before PR update. Since the deadline for data collection before PR update is probably known. So, we can speculate that the end time of data collection before the next PR update should be after mid-December, PR refresh (display update results) the time may be in mid-December (because googleguys once hinted at the adjustment of the new algorithm, the PR refresh (display update results) will probably be one quarter ).
