A few days ago, after I posted several messages on the Internet requesting website links, friends from all over the world came to me one after another, hoping to exchange links. If it were before, I would just link to them. , I have been doing SEO for a long time now, and I have gradually figured out the secrets. Now I will share my experience and skills with you. The writing is not comprehensive enough. Friends who do SEO can reply and add more!
1. For friends who like to do cross-links and group link exchanges, please be careful. Don’t be fooled by “borrowing flowers to offer to Buddha”. Some people tell you that cross-links are better than two-way links, and they have already prepared your link on site A, so that you can You link to site B, but site A is not his website at all, but a friendly link that your colleague has made long ago. Large websites with many external links and many managers sometimes fall into this trap. Although the short-term effect of group link exchange may be good, it will be brushed down or downgraded as soon as possible during the major search engine update, or even deleted by search K, so group link exchange is still quite dangerous. I generally prefer cross-links and group link exchanges.
2. When a friend asks you for a link, don’t be like me before and just link to someone without looking at anything. If the other party’s website is a spam website, it will bring disaster to your website. Before making a link, please note:
1. Check the other party's PR value, web page snapshot frequency and date, website inclusion and backlink status.
The PR value of the friendly link website should be equivalent to that of your own website. Today, a friend from Beijing asked to cooperate with me. He gave me four URLs (Beijing car rental websites). When I checked, I found that the PR values of his four URLs were all 4 or 5, but the friendship of each website There are more than 130 links, and some websites even have more than 200 links, so I feel that the weight of his website is too low, and it will not help my PR value. Then I checked the update date of his website. Some websites only have two snapshots. The snapshot times are 2009-6-19 and 2010-9-28 respectively. The number of included is only 2, so I refused to cooperate. If a website If the PR of the website can reach 5 or more, but its included number or backlinks are very few, then we have to consider whether the PR value of the website is real.
2. Check whether the link is a direct link. If it contains JS code or is scrolling, the quality will be much worse.
3. Check the other party’s website to see if it is a spam website
4. Check the location of external links on the other party’s website. Your link may be placed in the header area (main navigation area), main area (in the main content) or tail area (friendly links, sub-navigation copyright and filing statement) of the other party's website. Among them, the main area in the header area has the best effect, followed by The main area, and finally the tail area.
5. Check whether the other party’s keywords are reasonable. Be sure to look at the content of the other party's web page, and use the other party's relevant links to describe the text. You must not do it for him if the keywords are unreasonable, otherwise the search engine will think you are committing suicide and you will be finished.
6. Determine whether the other party’s website has been visited by Baidu. If you are K, you must cancel the link in time. Linking to a plucked website will definitely result in penalties. If the number of included items is only 1, it is likely to be downgraded. In addition, look at the snapshot date of the homepage on Baidu. If the snapshot date is more than a week or longer, then the website may be demoted by Baidu.
3. When you decide to link, you should pay attention to the following aspects to prevent being cheated.
1. Pay attention to the source code of friendly links, such as <a href=http://www.***.com title="Cash register software" rel="nofollow">Tana cash register software</a>, adding the nofollow attribute indicates that The link is not assigned any weight, and search engine spiders will not crawl and crawl along the link. This kind of link exchange is no different from a single-phase link. The situation is similar for dynamic script steering, or using JS files to call link code. There are also "links" that are better disguised. Although they are redirected, when the mouse is placed on the link, the browser status bar can display a normal link, so you should pay special attention to it.
2. IFRAME framework. Some people put friendly links in Iframes, and they were able to deceive a lot of people. This shows the importance of checking the link code.
3. Unilaterally delete the link. Delete it after a few days, or delete it after a while, making your link a one-way link. This is the worst and most disgusting low-level deception.
4. Fake home page. The homepage can be default.asp, default.htm, default.html, index.asp, index.html, etc. You must pay attention to which one is the real homepage.
Let’s write down the above details for now. We must pay attention to avoid damaging our website.
