Welcome to the Q&A Forum

Thank you all for the detailed response. I am going to use the suggested tools,  and get to the bottom of this problem. I will report back when I have some more insight. Once again thank you all for the detailed responses.

shouldn't be hard to check the robots file. go to www.yourdomain.com/robots.txt and tell us what that says. could be a server side issue as well even if they said "no changes.." looking at the sitemap might help you figure out what's happening. like, which of the 65 pages are missing. Are they all pages located in the same sub-directory? etc.

With the resources you seem to have with "employees" writing unique and relevent content that has value to your visitors, then you should already have a fantastic & comprehensive blog to showcase on.  If you don't then you need to put your efforts into building your blog and turning the tables so it's an engaging place that people will want to comment on, link to and all the other blog benefits. Stay well away from article submission sites, as Brad says, he ignores requests full of remorse everyday.  it's organic search karma, what we do today, impacts on our future!  Don't make your future, writing to people like Brad begging for the links to be removed.  Ain't gonna happen!

Structured data (microdata etc.) is markup that specifies what a section of a web page is about. So for example you can markup a review so that Google can identify the star ratings and knows that the product got a 4/5. This type of data is part of the semantic web - which is a WWW where bots like Google stop seeing Sites and start seeing entities. So for example in the current web a search engine might see links to a site with the anchor text "shoes" and interpret that to mean that the site is relevant for "shoe" based queries but if those links went to that brand's Facebook page the connection with shoes would be a lot weaker. In a semantic web the search engine would be able to tell very easily that a brand's Facebook and Twitter pages are part of the same organisation and that links to either count the same as to the main site. That's a pretty crude example (and to some extent search engines are already doing this) but you can see how it can affect SEO. That's not to mention the benefits that you can be getting right now from having rich snippets (Google them, they're cool). It depends on the purpose of the video. I'd put informational videos onto Youtube just because of the traffic floating about on the Youtube platform. I'm not an expert on video SEO but if you read this then you will be.

You are very welcome!
