Improving website ratings with the Search Engines

Whilst browsing the web looking for tools to help me improve the search engine ratings of my website Pen2Paper.co, I came across a really handy tool that provides you with a free assessment of the performance of a website and how it compares with the competition. The tool can be found at http://www.creatorseo.com/seo/SEOQuickReport.php I ran Pen2Paper.co through the tool and was provided with a summary of the overall performance of the website followed by an explanation of the results based on 3 criteria:
1. On page assessment - the site was analysed against 73 different criteria. Pen2Paper score was 64.7% (where 100% is the top score).
2. Keyword assessment - Based on the keyword phrase 'learn how to write books for children' - Pen2Paper.co score was 55.8%
3. Link assessment - uses incoming and outgoing links. Pen2Paper.co scored a tiny 3.5% and most of this score came from the 9 outgoing links on the home page. The 0.5% was associated with the small number (94) of inbound links.
Te overall assessment percentage for Pen2Paper.co was 48.9%

All the results are presented in an easy to understand graphical form.

This was really useful feedback on where I should concentrate my efforts in order to improve the ranking of my website with the search engines. From now on I plan to concentrate my efforts getting inbound links. I'll submit Pen2Paper.co to some of these and re-run the tool in a couple of weeks to see if I have managed to improve my website rating.

Please help me by suggesting possible sites that might provide suitable links.
