1, blog
According to my own experience, the blog posts published by Sina, Tianya and Alibaba are fast, with good weight, and can be directly linked to hyperlinks.
2. Forum
Now there can be many forums with strict censorship, and there can also be forums where soft articles can be posted, but many of them are either deleted or seconds old, and even fewer have direct links. It is good to send articles to related promotion forums with pure text links to attract spiders to grab the content of the website. Since the release of Baidu's green radish algorithm, the weight of the outside chain of the forum has plummeted.
3.B2B website
It is also good to register a B2B website and send a company friend chain with high weight. You can use plain text links to publish product information to attract traffic.
4, classification directory
To classify the catalogue, but many high-quality classified websites are collected quickly for fees, and it takes a long time to approve the free ones.
5. Monitor the opponent's external chain
You can directly Baidu related keywords, and the external information of opponents appearing on the first and second pages has high weight and can be used for reference; Furthermore, you can directly check the opponent's external information in the domain, and if you see something good, you will receive+practice.
