Context Our website has a large number of crawl issues stemming from duplicate page content (source: Moz). According to an SEO firm which recently audited our website, some amount of these crawl issues are due to URL parameter usage. They have recommended that we "make sure every page has a Rel Canonical tag that points to the non-parameter version of that URL…parameters should never appear in Canonical tags." Here's an example URL where we have parameters in our canonical tag... http://www.chasing-fireflies.com/costumes-dress-up/womens-costumes/ rel="canonical" href="http://www.chasing-fireflies.com/costumes-dress-up/womens-costumes/?pageSize=0&pageSizeBottom=0" /> Our website runs on IBM WebSphere v 7. Questions Why it is important that the rel canonical tag points to a non-parameter URL? What is the extent of the negative impact from having rel canonicals pointing to URLs including parameters? Any advice for correcting this? Thanks for any help!

My company made a branding decision to use lowercase for all of our title tags. This, of course, means that our titles on SERPs are all lower case. Overwhelmingly, it seems that websites use title case. This makes me wonder if we're shooting ourselves in the foot. Does using lower case titles negatively impact our rankings and/or click through rates? Is there any data out there suggesting that title case has a better click through rate than lower case? Thanks for reading!
