All seo's have their secrets on how they optimized and get rank their keywords. Here's some of my tips:
Most of the time internal linking creates a big problem, If you have too many links for your site, the spider will quit indexing your site before actually it is finished.
Always remember that links should always made with text. We can use images but it is not at all effective for optimization purposes.
The search engine discounts the importance of the pages of your site if your title tag displays more than one page.
