## About CheckSEORank

CheckSEORank is a web-based SEO tool that checks the Moz Domain Authority (DA), Page Authority (PA), Ahrefs Domain Rating (DR) and Moz Spam Score of any website. The site also shows backlink counts, referring domains, domain age and WHOIS registration details for a domain. Users enter a domain into the search bar on the homepage, and the page states that no signup or credit card is needed for the first checks.

The site offers a range of related tools, including a Backlink Profile Explorer, Domain Comparison, Bulk DA Checker, Domain Age Checker, Keyword Difficulty and several technical SEO tools such as a Robots.txt Validator and XML Sitemap Analyzer. Results can be exported as CSV or as a client-branded PDF report, depending on the plan. A Developer REST API is available on the paid Pro and Agency plans, with JSON responses for metrics such as DA, DR, spam score and backlink totals.

The tool is aimed at SEO specialists, bloggers checking partner sites before guest posts, digital agencies preparing client reports, and domain investors reviewing expired domains. A browser extension for Chrome is also linked from the site.

## About NotesIQ

NotesIQ is a Chrome extension for Substack writers who want to understand how their Substack Notes perform. It reads your Notes through your existing Substack session and shows them in a dashboard ranked by engagement, with likes, restacks, comments and content type tracked for each Note. A Viral Alert flags a Note that takes off compared with your own baseline, and the tool keeps a longer history than Substack's own dashboard, which the site says shows only the last 90 days.

The extension also helps with timing and posting. A 7-day by 6-time-slot Best Time heatmap is built from your own posting history, alongside your current posting streak. You can compose a single Note or load a week of Notes into a queue, and NotesIQ uses Substack's own scheduler to publish them at the times you set. A Media Kit feature turns your subscriber count, top Notes and engagement into a one-page sponsor summary that can be exported from the panel.

NotesIQ is aimed at Substack creators who post Notes regularly and want to decide what to write and when based on their own numbers. The site says your Notes, profile and subscriber stats stay in your browser's storage, with no NotesIQ server receiving them, and that the product is a one-time $4.99 lifetime purchase with no subscription.
