Welcome to the Q&A Forum

So I need to build a website with over 100 pages in it. Elements of the design will probably be moved around and or tested so I need to use a CMS. It's pretty much a review site so while the content will remain static I'd like to employ A/B testing to mess with conversion rates. Wordpress has a plugin for that even. So I'm just wondering, since CMS pages are pretty much created on spot and not retrieved from a library, how this affects backlinks and anchor text? How exactly does the external website point to yours if the URL is dynamically generated? Or am I misunderstanding something? Please recommend any extra resources as well if you can.

Hello guys, so I'm still wet behind the ears and am currently reading SEO an Hour a Day, as well as going through the Moz tutorial. But I do have a question that's been confusing me a bit. I've been doing keyword research here and there and I will get a "Highly Competitive" keyword (61%) at times. So then I try to go through each of the top 10 pages to see the anchors that they've used and how many backlinks there are to that page. A lot of the times the page with have 0 backlinks and a very low page authority (like 1) but it will still rank in 2, or 3. So what exactly makes it competitive? I know I must be missing something super simple here! Maybe I'm not accurately assessing the anchor/backlinks to that specific keyword. I use backlinkwatch, opensite explorer and the keyword difficulty report. Thanks guys!
