However, since you brought up recipes ... natural links from other recipe bloggers are fine, but it's good to avoid all of the link schemes & similar games that are sometimes played in that space. They're pretty obvious to our systems.
Но бывает, типа, когда плохо. Не жульничайте, дети.
Тяжело быть гугловым евангелистом.
