Welcome to the Q&A Forum

Hi Simon, If your sites are only a few hundred pages and Moz is crawling 50k pages, you definitely have some crawl issues on your sites. Reducing the number of pages Moz can crawl won't fix these problems - you should have a good SEO take a look at your site to find out why so many pages can be crawled and find out if they really need to be crawled (they probably don't). You can then take the appropriate steps to improve how search engines (and crawling tools) crawl your site by blocking access to these pages. There's really no need to change your Moz subscription level for this problem. Cheers, David
