today i looked into my website google webmaster account, and i suddenly found a bulk of 404 and non existing blank pages linking to my website categories ( i have an adult tube ) they are more than 100 website , should i disavow them all , and what should i do to fight such behaviour in the future ( is there any automatic method ) can someone explain to me the effect of that spam link building on your website rank and seo , i done 0 seo to my website but it is increasing not fast but in a good way but last sunday i experienced 100% increase in traffic to my website and then it decreased after two days to less than 10% than expected , and can i know who did that to me , are they random people just backlinking to everywebsite in internet like this using senuke and GSE or can he be an ennemy ( majority of spam domain names are registered with brazilian names which make me think it is not a conspiracy just against my website , but then i say maybe it is a list used by a lot of people so an ennemy found it and start using it against me ) last question : should i disavow those links in google ,bing and yandex or only in google Thanxxx
These kind of links can harm your website. If you find anything wrong, then you should take immediate action
