  Peter Thomas: Cannibalisation (I'm fairly new to SEO, so apologies if this is really dumb): how do I stop my second level pages from cannibalising keywords which are in the first level url?

  Dmitry Grunt: Remove keywords from H1, titles and text.  ;Optimise only one (landing) page for one keyword.

  Peter Thomas: The page I want to rank higher for is sylpheo.com/heroku-partner (for heroku partner') but ;sylpheo.com/heroku-partner/heroku-faqs/ also ranks for the same thing.

  Greg Baka: +Peter Thomas - cannibalizing was more of a worry a few years back. Changes to Google have made it a minor concern.
  
  You said your FAQ page also ranks - this is a good thing as it means your site appears in the search results multiple times and there are more chances for a potential customer to click on it. Also having both pages ranking gives more opportunity to appear for long tail keywords.
  
  If at least one of the pages is ranking reasonably well, I suggest doing nothing about cannibalization. If both pages are ranking poorly, you can experiment with improving things by putting a canonical tag on the FAQ page pointing back to the first level page. That will transfer part of one page's strength to the other.

  Peter Thomas: Thanks Greg. Both pages do rank well - top of page 2 (google). I was hoping to just push one over the top.

  Richard Hearne: Does your FAQ page link to your Heroku Partner page?  ;If not add a nice inline link with target anchor text to see if you can push your partner page up a little. I'd do this even if there's a link within your nav to the partner page - inline links probably throw a little move weight across than nav links.

  Mach Page Speed: +Peter Thomas ;
  Run your page through w3c validator and you will see you have errors and warnings on the page. Fix these.
  
  Optimize your page the best you can for page speed. Currently loading at 6.5 seconds. Focus on the images first since they have the biggest impact. Defer the iframe youtube video loads if you can. Will be a huge impact on speed also.
  
  Look at providing alt tags...some are empty and some are generic.
  
  There is not a lot of content on the page...more of lists than anything.  ;Might want to look at providing that using schema.org in the form of rich snippets.

  Peter Thomas: Thanks for all the advice - I will do all of those things.
