First, quality is higher than quantity.
Quality is higher than quantity, no matter how many low-quality chains you make, they can't compare with a high-quality chain. Don't take the number of foreign chains as the index of your work, but put quality first, otherwise it will be in vain. In particular, we are opposed to using software to send out-of-chain spam. This may have a temporary effect, but in the long run, it may lead to the degradation of your website. In fact, the principle of outer chain is aimed at the artificial and deliberate construction of outer chain, and it is also a last resort for new stations and small stations. If it is a website that really wins with high-quality original content, artificial external link construction may even be unnecessary, so there is no need to blindly follow, and an appropriate amount of external links is enough.
Second, the greater the difficulty, the higher the value.
Anyone who has actually operated SEO knows that original content and external links are two difficult tasks, both of which are time-consuming and laborious. External chain can't even guarantee that there will be output if there is input, and it is even more difficult to get a good external chain. But generally speaking, the more difficult the link, the better the effect. Like Baidu Encyclopedia, the review of external links is very strict, so once the external links are successfully left on it, the effect will be far greater than the general forum. SEO personnel should never give up because they are rejected at the first contact. Many times, you need to contact each other many times to get links to blogs, news websites and forums with high weight. Sometimes you can't come up and ask for links, but you should make friends and help each other first. After having a certain friendship, you can ask a link to become natural. Some websites with high weight do not accept friendly links. Only when the other party knows you and trusts you can they give you a one-way link. This process may take several months, and the harder it is to get links, the more effective it is.
Third, content is fundamental.
High-quality content can bring high-quality links, because high-quality articles are often easily reprinted. This is an external chain construction strategy from the inside out. Simply put, if you want the other party to link to your website, you must provide value to the users of the other party's website, and the most important value is high-quality content. There is no free lunch, no high-quality content, and the links you get can only be exchanged, purchased or spam.
Fourth, the relevance of content.
Content relevance is one of the most important considerations when looking for effective external links. Content-related websites are more directly valuable to each other than those unrelated websites, and the external links between websites in the same industry are of high quality, and their functions will be maximized. Therefore, it is very important for many people to visit other people's blogs in the same industry and leave messages, exchange and support each other and become active participants in the industry. If it is not relevant, it is ok, but the effect is not very good.
Fifth, the extensiveness of the external chain
A normal website can't be full of good links, but there are no ordinary or even poor quality links. When constructing the external chain, we should also make the external chain generally natural, random, and widely sourced, showing healthy and normal characteristics, otherwise it is likely to be recognized by search engines as deliberate and ultimately unable to achieve results. Pay attention to the diversity of website types when doing external links, and don't leave all types of blogs, forums and new websites. Don't ask too much for the PR value, you need all kinds of PR values, both for new stations and old stations. If all the external links of a website are from pages with high PR value, it is very suspicious. According to common sense, I am afraid that most of them are buying links. When doing external links, you should also pay attention to not always linking to your home page, but both pages should be on the home page. Don't fix a word in the anchor text, but highlight the key points on the basis of diversification.
Sixth, deep links.
Deep links not only make the composition of external links tend to be natural, but also have a great influence on the weight of internal pages. I noticed a phenomenon that the PR value of the homepage of many websites is good. Under normal circumstances, the PR value and weight of the first-level classified page should be only one grade worse than the home page (for example, the PR value of the home page of my website is 5, and most other channel pages are 4). Actually, not necessarily. Many first-level classified pages have a PR value of zero. Judging from the ranking ability, it seems that these classified pages do not all get the weight of internal link transmission. Only when these classified pages have external links, the PR value, ranking ability and weight will be promoted to their proper positions.
Seven. increase steadily
The external chain must keep in mind the steady increase, and don't rush for success, especially the new station. If your website suddenly adds a large number of external links overnight, it will be easily identified as cheating by search engines, and it will not be worth the candle. Don't make these unnecessary attacks. Websites and external links that are really useful to users are increasing steadily over time, and there are few ups and downs. Learn to allocate energy reasonably, control time well, add some every month, and continue. Therefore, in the process of chain construction, it is necessary to make a good plan, make clear the goal, step by step, and increase the chain on a regular basis in order to achieve good results.
