I want to optimize my youtube channel using identified keywords, but I'm concerned that the keywords I'm identifying work well for SERP's but might not be how people search in Youtube. How do a distinguish my keywords to be targeted for Youtube?

We've had a few questions regarding the new Keyword Difficulty score used in Keyword Explorer, and how it compares to the old score in our stand-alone Keyword Difficulty tool. Specifically, people want to know why some scores are much lower using the new tool. There a general discussion of the math behind the tool in this post: ​Keyword Research in 2016: Going Beyond Guesswork One of the problems we had with the original Keyword Difficulty score is that, because it's based on our Page Authority (PA) score and PA tends toward the middle of the 0-100 range, Difficulty got a bit bunched up. A Difficulty score in the low-to-mid 20s (via the old tool) is actually very low. So, we set out to re-scale the new tool to broaden that score and use more of the 0-100 range. We hoped this would allow more granularity and better comparisons. While the logic is sound, we're concerned that we may have been too aggressive in this re-scaling, given recent feedback. So, we're going to be analyzing a large set of keywords (anonymously, of course) that people have run through the tool to see if too many Difficulty scores seem too low. If they do, we'll make some adjustments to the math. In the meantime, please be aware that low scores may appear lower in the new tool and very high scores may appear higher. We wanted to address some of the limitations in V1 and feedback over the years, and so the old and new scores really can't be compared directly in a meaningful way. We're sorry for any confusion that has caused, and we will re-evaluate if necessary.

Hello! Moz reports that my site has around 380 duplicate page content. Most of them come from dynamic generated URLs that have some specific parameters. I have sorted this out for Google in webmaster tools (the new Google Search Console) by blocking the pages with these parameters. However, Moz is still reporting the same amount of duplicate content pages and, to stop it, I know I must use robots.txt. The trick is that, I don't want to block every page, but just the pages with specific parameters. I want to do this because among these 380 pages there are some other pages with no parameters (or different parameters) that I need to take care of. Basically, I need to clean this list to be able to use the feature properly in the future. I have read through Moz forums and found a few topics related to this, but there is no clear answer on how to block only pages with specific URLs. Therefore, I have done my research and come up with these lines for robots.txt: User-agent: dotbot
Disallow: /*numberOfStars=0 User-agent: rogerbot
Disallow: /*numberOfStars=0 My questions: 1. Are the above lines correct and would block Moz (dotbot and rogerbot) from crawling only pages that have numberOfStars=0 parameter in their URLs, leaving other pages intact? 2. Do I need to have an empty line between the two groups? (I mean between "Disallow: /*numberOfStars=0" and "User-agent: rogerbot")? (or does it even matter?) I think this would help many people as there is no clear answer on how to block crawling only pages with specific URLs. Moreover, this should be valid for any robot out there. Thank you for your help!

A search term in MOZ shows the monthly search volume to be 49K. In Google, the same term shows the search volume at only 1300 monthly searches. Which do I trust? Thanks, Don

When setting up a campaign for keywords and selected search engines. I am targeting a UK market so obviously Google.co.uk is my main target. However when I set up the campaign i select Google as the SE but it asks me if I want United Kingdom or Great Britain. I selected United Kingdom and it has been returning 0 results for rankings even though I can physically see them in the SERPS. Does anyone know exactly what is the difference between the UK and GB options. I assume I should of specified GB but not sure. Any help would be appreciated. Thanks
