Блокировка ботов и снижение нагрузки на сервер

Исследуя логи сервера, можно найти огромное число ботов, которые буквально атакуют ваш сайт изо дня в день, создавая огромную нагрузку на сервер. Блокировка ненужных ботов – логичный этап развития крупных проектов.

Вторая сторона медали – исследование вашего проекта конкурентами через сервисы, например: ahrefs, semrush, serpstat, linkpad и другие. Если вы делаете SEO-продвижения с помощью PBN-сетей, через эти сервисы можно очень легко отследить всю вашу сеть, после чего “настучать” в Google для последующего бана всей сети сайтов читера. Чтобы этого не случилось, следует уделить время закрытию от ботов этих сервисов.

Есть и другие преимущества от блокировки, например: частичная защита от воровства контента, защита от замысла ддос и хакерских атак. Обычно все это делается с предварительным анализом сайта, которые проводятся некоторыми из нижеуказанных ботов.

Напишите в комментариях, нужно ли расписывать, к чему относятся каждый из ботов выше (название сервиса и другая информация)?

Как заблокировать AhrefsBot, SemrushBot, MJ12bot и других ботов?

Существует 2 известных мне метода надежной блокировки от плохих ботов:

  1. Через блокировку входа в файле .htaccess, тоже находящийся в корне (рекомендуемый способ!).
  2. Через блокировку в файле robots.txt, который находиться в корне сайта.

Если вы знаете другие методы, обязательно напишите в комментариях!

Закрытие плохих ботов через .htaccess (рекомендую)
