I've been considering blocking third party crawlers for a while – specifically those crawling my website for the sake of competitive analysis, such as SEMrush and Ahrefs. I'm familiar with how to do so, but when researching the question I found practically no one asking the same question. The guides I've found on what to put in your robots.txt make no mention of whether to block competitive analysis crawlers. Which makes me wonder whether this is a good idea after all. My chief concern here is rival sites going after the same search terms we target – one of our competitors in particular has an uncanny way of going after the same searches we are. I know blocking crawlers won't prevent competitors from watching our content, but it will make it slightly harder for them. Is there any major drawback I'm missing? Any big reason not to go ahead and block SEO analysis crawlers?

I've been seeing some search results for my site that look like the first result here, where the URL slug is used as SERP title: https://drive.google.com/a/fitsmallbusiness.com/file/d/0B37y4RslpuY-a0hQYjlJQ0NxeFJicDF6RVlURFVSNFN0aGhB/view?usp=sharing The article title (and Yoast snippet title) are both "28 Press Release Examples From The Pros", but for some reason I'm seeing "press-release-examples" in the search results. I've seen this for multiple articles, and I see it now and then with different articles. I'm aware that Google often changes the titles in search results, but it seems very weird to me that they would opt for just the URL slug here. Thoughts? Has anyone else seen this issue? Any idea what might be causing this? All help much appreciated.

Anybody have thoughts on dealing with search results where the same site gets listed multiple times? "weebly vs wix" is one example (same site #1-3, repetitive articles, not crazy high authority), but I see this now and then. I know Google likes variety, so it's weird for me to see results like this dominating search results. Thoughts? What gets these sites to take over the top rankings for a specific term? Any way to rise up in this situation, outside of the usual? Any tips on duplicating this kind of success?
