Choosing anchor text in GSA Search Engine Ranker

[andla]

Hi this question is about picking the right anchor text when creating backlinks to a tier 1 network.
What option would you choose if you had a Web2.0 blog network with auto scraped content:
1. Pick the meta keywords and create a url#{meta keyword1|meta keyword2} solution.
2. Pick the meta title and use that in a url#{meta title} solution.
3. Pick 1 and 2 both.
4. Use the primary and secondary keyword list of the money site (not the tier 1 blog network) in a url#{keyword1|keyword2} solution
5. Use 1 or 2 with 4.
6. Use 3 and 4.
Appreciate your help on this.
Cheers
