As far as I know, page backlinks are more specific and thus are more important.

It's good to get BOTH, honestly. How would it happen naturally? You'd probably get MOST links to your home page, but still plenty to your pages/posts as well.

Personally, I send MOST of my links to my domain, as there's where I focus my main 'conversion' efforts, however it's still important (and natural appearing) to link to your pages and posts, so alternate to give it more of a 'natural' link building effect.

On the other hand, if you're wanting to focus on one particular page - then it's ok to focus on that one a bit more too. Just change it up and don't ALWAYS do the same thing over and over, keep google guessing and you'll do well.

I'm sure others will say otherwise possibly, but this has been working for me quite well.

You should focus on building links to whatever page you are interested in ranking for your chosen keyword. If it is all 18 of them then you will have to do some prioritizing as well as use lots of automation.

So if I have 18 keywords, I need to anchor text each one individually link to that specific page. Sounds good! Maybe I'll outsource a few to some people and see that the results are...

Start building links to your home page first and then focus on targeting internal linking pages.

When making backlinks, be sure to link it with websites with higher PR.

and also, try to make a backlink in related niche market. for example if your site is about dog, try to have a backlink with related dog site.

The quality links u built are best strategy

send your links to the pages you intend to rank. It depends on how you built your site and where you want people to enter your site.
