Your website crawl-ability is very much responsible upon your on-page activities. You can't rely upon a tool to identify errors in your website, therefore you should focus different different sources like GWT "Crawler Errors" (a free tool), screaming frog, xenu, seomoz tools, seobook tools, web developer toolbar by chris.

what is with the anchor text? Not getting what do you mean?

 

Depends, if you're using something like Wordpress to develop you're website i recommend you check out Yoast SEO Wordpress plugin. It will analyse every post, and will allow you to change the keywords, description and title that will show up in google.
Just like someone above already shared:
1. Title tag - must contain your keyword. Not more than 70 characters. Not more than 5 words.
2. Meta Description - has more an marketing role than SEO. Not more than 160 characters. Make it more attractive and with call to action sentences. This will not increase your SEO - so no need to put your keyword in.
3. Use keyword in an image (keyword is the alt tag of the image)
4. Use keyword in text body (do not bold). Use it in H1 tag, H2 and H3.
5. Use long tail keywords in your content.

6. Ad an social sharing option. AddThis plugin is way to go.

Remember, if everything matches (the title, description, keywords and in-post text) with the title of the post (example: Hello test test) in which: the description is Hello test test, the keywords are Hello test test, and in the post there is: hello test test
image alt tag is hello test test

it's the best chance on getting good SEO.

 

Hello Mate
Please try this one: visible[dot]net/tools/analyzer/
It is really helpful to improve on-page SEO...

 

Rather than depending on tools for improvement, you must use the tools only for detecting errors, if any, and fix them manually. Google webmaster tools help a lot in finding the errors in the website.
