Seo optimization-External link addition skills and precautions

1. Websites exchange links directly

1. Exchanging links between websites is a way for websites to be associated with each other. When linking, be sure to check whether your linked website is related to your website content, in this way, search engine tutorials can add a lot of weight to the relevance of your links when searching pages. Otherwise, the search engine considers the website to be spam ads.

2. Website pr: website pr is a measurement standard for a website. You must pay attention to this issue when switching a friend chain. Do not stare at the pr level and ignore the pr output value, in addition, the number of external links of the other party cannot exceed 30.

3. Connected words: the connected words can increase the weights and rankings of related keywords. Therefore, it is best to use keywords to link friendship. This reminds you of the words that the search engine is about to crawl. However, do not exchange friendship links for a keyword multiple times in a short term. This can easily lead to K keywords, which is especially serious in Baidu, in addition, even if you use your website name as a connector for a short period of time, Baidu will be considered as an optimization or K.

4. The snapshots, number of records, and domain name history of the linked website are also very important. The snapshot must be within three days. The larger the number of entries, the better, and the difference between Google and Baidu cannot be too large. Domain name history can be queried through tools, which reflect the weight and friendliness of the website domain name in the search engine.

5. Do not change the direct link adopted by the other website. Many websites will use js and jump to your website with other code. This means they will not connect to you, it can also be regarded as cheating. Even the link to his inner pages is not counted, and it does not make much sense for inner page links.

II. External single-chain

External single-click links are unilaterally linked to your website, but you do not link to the other party. This is a very common practice and the search engine has a high degree of attention and weight on the links, therefore, many people will write blogs to log on to various link directories. However, when logging on to the directory, you must be sure not to log on to a page full of illegal advertisements. This affects the credibility of the website. Therefore, the quality of external links is very important.

3. Tips

1. Do not point to the link directory.

2. Do not swap the internal pages without PR. Do it as a single link.

3. Don't make friendship with websites with many links. You can't find anything and you can easily get yourself in.

4. Do not always change the link, which may cause search engine suspicion.
