Welcome to the Q&A Forum

Our company uses a custom CMS for each of our niche classified websites.  Ideally, we would like an online/cloud-based platform that would generate our sitemaps for us.  Dyno Mapper looks like a good contender, but the $108 monthly fee seems a bit steep.

Hi there! Ahrefs is a link index, similar to our Mozscape index. If you're not using Ahrefs for any metrics, you should be safe to block it.

You can use Screaming Frog for this (and much more). It's not free but is great tool to check the SEO health of your site as well. Trial is free (up to 500 url's). To generate the sitemap - crawl  your site with following settings: Configuration > Spider > Advanced tab: select: always follow redirects respect noindex respect canonical After crawl - under the Sitemaps you can create the XML & image sitemaps.

No, we were using them for the proper indexing of our mobile pages. I've instructed our Dev team to continue using clean mobile URLs.  I imagine clean URLs would only increase the likelihood of better ranking since it's indexed sooner than the actual page source.  Especially with search engines working towards semantic search, it would be natural to assume URL structure would carry some weight. Thanks for your input, Kristina!

Mat's right. Your content does need to be readable, indexable, and crawlable. It sounds the resulting content will still be HTML output of some sort; however, you are stating that you won't have access to any actual static HTML files for SEO purposes. If this is the case, the backend needs to be extensible enough to allow you to still do your job as an SEO. If you can't provide unique Page Titles, descriptions, canonical link elements, etc..., your organic search results will suffer. Here's another issue: if your pages are built with JavaScript, you need to make sure the output is readable by search engines. I've seen issues with JavaScript-built pages before where search engines are indexing "blank" pages, indexing the wrong pages, or seeing duplicate content where AJAX is used to inject the unique content after the page is ready and has already been crawled.
