Welcome to the Q&A Forum

Run queries in google to see what your competitors are doing. Find articles that help with inspiriation, and then write a better, unique version to help bring additional value to the customer.

An example query I just tried real quick was

• "leather office chairs" inurl:blog

Most importantly, follow all of the suggestions in the site crawl report, and tackle as many of these as you can. Here are some of the free tools I use regularly that can help you take your efforts further.

• Use the free dashboards and custom reports from the google analytics gallery to get more insight into your traffic and to identify any errors (outside of what you see in moz).
• Google Data Studio (Free) also has reports you can use for keeping track of different metrics and it connects directly to google analytics and search console.
• Google Sheets has a free addon for google analytics and search console data that allows you to schedule automatic reports, once you have identified errors you want to monitor.

Aside from metrics, content is king, and you will benefit greatly from researching your target keywords, and posting articles that include links to the related pages.

Is it a permission issue, or are you not comfortable editing any of the technical aspects?

What platform is your website running on?

Yes, you can return multiple rich snippets for the same query. With SERP features, there are also several different ways to appear on the SERP for the same query. Videos, Photos, Q&A's, etc.

Your mileage will vary based on how well you rank for the term, the features that are currently present, and your sites authority on the subject.

The canonical option would be the route I went with in this scenario.

If you are going to noindex them, make sure that you audit the pages to see what links are pointing to the pages. If there is value them, canonicalization would be a better approach.

Buzz bundle, and link assistant from seo power suite has tools for this type of usage. You can also save "persona" profile information to create accounts on websites automatically. You will likely run into issues with captchas, but you can add a death by captcha account that allows the program to solve them automatically.

For a more manual configuration, you can automate several components of what you want to accomplish using scrapy or beautiful soup tools for python to gather form fields and properties from a the list of urls with regex conditions.

You should be fine either way as long as there is anchor text and a link being rendered on the page.
