SEO Tool PHP

Hi I need the following tool created that would check a [login to view URL] and grabs all of the information from the website. I am not looking for any styling or making the pages look "Pretty", i just want the functionality. As i will be embedding this into an existing custom CMS. Page 1: There should be a button at the top that will grab the sitemap, and run the script. Below this, would be a table with all the issues. 1 row per page, with a number for the amount of issues found. You can click on "View" to see the full details of issues for that page. Page 2: This will display all of the issues with the page. There should be a button to "recheck" which will only recheck this page. Ideal for someone that's working on the page and wants updates. These are the issues i will want it too look for: Page Title Issues: - Length of page title - Does it exist? - Meta Keywords Issues: - Length of Meta Keywords - Does it exist? - Meta Descriptions Issues: - Length of Meta Keywords - Does it exist? - OG tags (Facebook/Twitter/Google+) - Do these exist? Images - Number of images, and Alt & Title tags (also check for broken images) Links - Internal and External Issues: - Do links contain title tags? Heading Tags Issues: - Does H1 exist on page? * - Is there more an 1 H1's on the same page? * - If there is any more heading tags (H2, H3 etc.) then you need to check to make sure that its tag is only used once per page. (Here don't need it to raise as an issue if no H2 exists, only if more than one is present) Page word count (the number of words in the content areas). If this is less than a threshold then it will raise as an issue. Duplicate content check - The pages' content should be checked against the other pages in the sitemap. To see where any duplicate content may exist. Left side should be the original trimmed text. Right side would be the other pages that it has matched. The matched text should be highlighted on both sides in different colours. All the data should be store in a MySQL database. Thanks
