When checking through one of my post, I realized that I have given backlink to spammers. Spammers give trackback to my post, thus the post in my blog gave backlink to them. It is bad to give backlink to spammers, because Google can penalize our blog. Do not give backlink to blog that Google hates (spammers). There are two ways to tell whether a blog is spammers or not:
- Go to Google and search “site:domainname.com”. Change the “domainname.com” with the domain name you want to check. If they are spammers, Google with not show any results.
- Spammers usually have “?p=67365” on their links. The links contains ID of the post.
To delete the previous spammers link that I have approved, I went to PhpMyAdmin, and do execute this query:
WHERE comment_author_url LIKE ‘%?p%’
This will return all comments that have “?p” in their links. Then I will choose the comments which I will delete.
