What is Directory Submission?
ディレクトリの送信とは、Web サイトの URL を Web ディレクトリに送信することを指します。
A web directory is a website that contains links to other websites. They can be free, paid, or reciprocal.
- A free directory will link back to your site for free.
- A paid directory will link back to your site in exchange for payment.
- A reciprocal directory will link back to your site for free but requires you to link back to their site in return.
Google considers directory submission unnatural linking. Directory submission may also be considered a black hat SEO technique if done inappropriately.
