Inbound links to IP addresses: Google denies that they discriminate against links from the same IP address or Class C address, so Google's IP address can be considered a neutral inbound link weight.

13. Links to inbound link farms and other suspicious sites: Presumably, this does not affect you and offers links that are not reciprocal. The idea is that you can't control the definition of a link farm that links so you won't get penalized when these sites link to you because it's not your fault. However, some recent changes to the Google algorithm suggest the opposite. That's why you have to stay away from link farms and other suspicious sites or if you see them link to you and contact their webmaster, please link is deleted. 0

14. Many external links: Google does not like the page mainly by the link, so you'd better get them on page 100. There are many external links that do not give you any advantage in ranking may even make your situation worse. -1

15. Too many links to link spam: This is not good for your rankings when you have a lot/links from the same site (even if it is not a cross linking scheme or bad neighbor link) because it indicates at least link purchase or spam. In the best case only consider some links to SEO rankings. -1

16. Outbound link farms and other suspicious site links: With inbound link farms and other suspicious link sites, outbound links bad neighbors can drown you. You need to regularly check the status of your site links because sometimes good sites become bad neighbors and vice versa. -3

17. Cross-linking: Cross-linking occurs at the site link site b,site b link sites C and C site links back to the site A: This is the simplest example, but more complex scenarios are possible. Cross-linked look disguised as reciprocal link transactions and penalties. -3

18. Single Pixel Link: When you have a link that is a pixel wide this is invisible to humans, so no one will click on it, obviously, this link is an attempt to manipulate the search engine. -3
