What happens if 20 links become 1?

[gorhansan]

Dear great Moz community,

I have a question regarding links.

Currently my website is listed on a site that requires that I pay money every year to get my products listed there.
However, I will not be paying this year. I will still be listed on the page (1 link towards my site) but my products will no longer be displayed. (around 20 products with links).

Will this affect my rankings? or is one link from the page enough. Hence: all the links from that site were pointing towards the same place, my homepage.

Summary: 20 links become 1 link towards my website, will it affect the ranking of my page?

Thanks for all the help I really appreciate it!!

Highest Regards,

Gorhansan

The short and generic answer is yes, it will lower the strength you're receiving from that site but it won't drop it to 1/20th.

More links is a good thing if those links make sense but the more you have, the less strength each of them carries; 20 links will not offer 20x the strength of 1 link, if that makes sense
