Goggles difference in links and pages

I checked my site with Goggles and it tells me that my links are OK and the help video says more links on my webpage the better. Then I went back and listed like 12 of my internal links on the webpage and my links score went to poor.  So, I'm not understanding the difference between links and pages? I'm shooting for the best quality score to keep my PPC low and I'm trying to get a GREAT in every category possible. So I'm confused as to how to improve my page score and link score.  On anther thought, my landing page is OK under Goggle, but when I check through everything, my headline and Meta TAGS MATCH my keywords, my keyword density is between 1.5% and 2.69%. I've heard going over 3% is bad.  I have more than 250 words on the page, so I'm doing all that I know to do, except I haven't added a video on the page, so how can I improve my landing page? Lastly, on all my keywords Goggles give me a click through percent of 1%.... How does it know the percent, and more important, how can I improve it.. BEFORE launching the PPC camaign? This is a lot I know, but any help or feedback would be greatly appreciated.

So, I'm not understanding the difference between links and pages?

Pages

You want to have at a minimum 5 pages with good content. They should be interlinked in a silo structure.. looking something like:
printers
/\
laser printers - inkjet printers
/\                    /\
accessories - HP - Canon

As you can see they break down from broad to more specific. For more on siloing see our friends at themezoom.com

Links

These are external links going to authority sites, articles etc. You can have a resource page on your site that links out to useful information.

How can I improve my landing pages?

Did you add sitemap? did you hide affiliate links? It seems you are headed int he right direction. Add pages and external links and you will see an imporovement.

How does it know the percent, and more important, how can I improve it.. BEFORE launching the PPC camaign?

We default to a CTR of 1%, you can use the slider to adjust and see what effect the ctr will have on your keywords.

Hope this helps. Let me know if you have any more questions.
