Hi afanasi,
Samuri rocks, but i here there is a bit of competition for this keyword tool.
I have often wondered about the backlinks they list. You say -
145 page backlinks and 327 domain backlinks.
well, as you know yahoo gives a more complete list of back links, and i suspect that sam only counts the links that Google lists (ie uses for working out which site is best). So your competitor probably has many more links to both pages.
I look at all the factors in the sam table. I figure for a mid to long tail keyword that you can get away with a moderately young (new) versus old site, as long as you get all the basic on-page seo right, and you can compete on PR and back links. If the list is full of PR 3 and higher I know its going to be tough, and likewise your page links numbers are also a considerable hurdle to surmount - since you are going to need to link from high PR authority sites (not the same one over and over).
But specific to your question, I usually rate the specific page links much higher. I know that you can get high serps for a page with low links if you have a mass of visitors to your homepage, and they spill over to that page, but not every large site can guarantee that. I think its a blessing when i see a competitor near the top that has its sub dir listed rather than its homepage, after all, you are probably using the keyword as your URL, and you are pitching your homepage against their sub? So you are going to be putting all your efforts at your homepage to start with.
I usually feel much more confortable going against long tail keywords and competitors with 50-100 links to the specific page.
So as you know, its probably down to the content you can create, then spin, then auto upload etc etc. You are more likely to be more dedicated than the site you are going against (re seo for that term) - so the future looks good.
just my opinion .... G Luck!
