They also let me choose between a homepage link or a link in a blog article.
If the homepage link is...
- sticky
- surrounded by text
- with less than 10 other links like yours on the same page (the homepage, of course)
- on a site with decent google traffic and no downward traffic and ranking trends
- on sites that are relevant to yours
- priced acceptably
ALWAYS choose this type of link, it works very well (although you shouldn't have only such links, you should still get other types too, but the ranking power comes from this type of link most of the time)
What kind of minium metrics (DA PA TF CF DR RD) would you choose to determine the quality?
there's no exact number to give because each case is unique. In certain niches and / or for certain keywords you might rank with only 2-3 links, in other cases you might need 5000 of them (no exaggeration). It really depends on what type of competition you're up against and how good your site is in general and when I say good I refer to authority more than anything else as authority (DR / DA) seems to be one of the biggest ranking signals nowadays, so you gotta pump that metric up if you want to stand a chance.
TF and CF are metrics invented by MajesticSEO and if memory serves me well (I've been out of the SEO game for nearly 3 years) back in the day I used to aim for a TF:CF ratio of 0.7 to 1.5, I think the sweet spot was within this range back then.
But TF and CF are not the most important things, these 2 metrics usually speak about the relevancy of a site, but many times strong links can be more impactfull than relevant ones, so you should ideally aim for backlinks that come from pages with high PA or UR in the first place, and with good TF / CF in the 2nd place... although, I'd argue that traffic is actually more important than TF / CF, so the TF / CF metrics should be considered 3rd even
