Плагин Noindex Links (старое название WP-Noindex) запрещает Яндексу учитывать ссылки в комментариях. Плагин оборачивает noindex тегами как ссылки авторов комментариев (если они заполнили поле “Сайт” при написании комментария), так и ссылки в тексте самих комментариев.
Яндекс давно уже учитывает “nofollow” атрибут у ссылок, но среди SEO-специалистов бытует мнение, что полностью игнорировать ссылки Яндекс будет только, если они заключены в noindex теги (в пользу этой теории говорит появление в последнее время нескольких бирж по продаже nofollow-комментариев).
В версии плагина 2.00 простые теги <noindex></noindex> заменены на валидные эквиваленты <!–noindex–><!–/noindex–>. Более подробно читайте на <a href="http://www.wordpressplugins.ru/seo/wp-noindex.html" rel="nofollow ugc">странице плагина</a>.
Если вам понравился мой плагин, то пожалуйста поставьте ему 5 звезд.

Noindex Links

Плагин заключает любые ссылки в комментариях в теги <noindex></noindex>.
