help me decide on a domain for link building agency

[links12]

Hello, I'm considering several options for the domain of my link building agency and would appreciate your input.
The choices I have in mind are:
1) authoritylinks.com
2) linkslab.io
3) linklab.io
4) backlinklabs.io
5) linkslabs.io

Which one do you think would be the best?

linklabs.io although that's not on your list for some reason

linklabs.io although that's not on your list for some reason

that domain is not available

Ahh, that's a shame.
If that's taken I wouldn't go for anything that looks similar as this could raise confusion and linklabs is probably the best name out of those choices.
Maybe backlinklabs could work.
