Hello, These days you can find lots of SEO software that provide onsite seo tips, but it seems they are different from one product to another. I want to implement my own tool for checking page optimization, but I need some proven onsite checklist (maybe published by some authority site) to use as a guide. For example, is it written somewhere that titles should exceed 80 characters in length ? Is there a lower limit for titles ? What about length of the H1 tag ? ... you got my point. Thank you
Try Web Auditor Tool from Link Assistant's SEO Powersuite Tool .. It's a very useful software for auditing the pages of your site. Also, you can SEOMoz Site Explorer
Hope this will help you, http://www.viewsyntax.com/2012/04/steps-to-follow-before-publishing-post.html
+1 to Website Auditor for on-page. However, bear in mind that no matter how good and intuitive an SEO tool is, it still is a machine, and cannot predict every situation. So, I'd take the recommendations it provides with a grain of salt. Have you used Siri, for example? Sometimes it is spot on, sometimes it's simply wrong. So, I think , you should be studying a bit more theory and practicing on-page with the help of SEO tools at the same time
I've used SEOMoz audit with some success in the past. There's a bunch of other site-audit tools out there. An alternative: go to fiverr, there's plenty of people that will do a site audit for you for just $5. But honestly you're better off either buying your own or finding a free list/service. Other than that...google's your friend
No one tool is 100% accurate especially with the latest google Panda update, over optimisation of the page has now become a big factor in on page seo.
