Welcome to the Q&A Forum

Thanks - Bruce

Thank you - I think i will try to remove as many as possible, and then disavow other they cant remove.

I have just started using Open Site Explorer and discovered a lot of spam links to my website.
(I have mostly ranked on page for many years one but in the last two weeks ranking have dropped to page two)
The links have Anchor Text such as Scam - Dishonest - Drugs. Most of the of the links are "nofollow".
Will links with "nofollow" affect my ranking and if so which of the links should i priorities to remove?
Do I look at  Link Equity - Domain Authority - Page Authority or other criteria?

Many thanks
Ronny
