A: Hi Shi! Thanks for your questions :)

1. We crawl over 7.1 billion web pages daily, which is fewer compared with Ahrefs, but it provides a decent amount of backlink data for SEO, especially if you're on a budget and can't afford pricey platforms. The important thing about our algo is that we try to collect the freshest data, as well as the backlinks from high-authority domains in the first place. Sure thing, our team's working on improving the crawling and growing our backlink index - that's one of our high-priority tasks at the current moment.

2. SEO SpyGlass is part of the SEO PowerSuite bundle that also includes WebSite Auditor (a site audit and content optimization tool), Rank Tracker (a keyword research and rank tracking platform), and LinkAssistant (a link building and outreach tool). If you're interested in content analysis and keyword research, I highly recommend you to check out Rank Tracker (https://www.link-assistant.com/rank-tracker/) and WebSite Auditor (https://www.link-assistant.com/website-auditor/) There's a free fully-functional trial available on our website in case you want to try them out!
