FreeChemDraw is a free online chemical structure editor based on open-source Ketcher and OSRA; integrates with ChemTradeHub to fetch structures by CAS, formula or name.
DevAIOHub.com saw its DR rise to 7 on the second day after launch. The author summarizes the steps taken post-launch, including adding Google Search Console and Bing Webmaster, submitting to Product Hunt and fazier.com, posting on v2ex.com, publishing on Startup Fame and Peerlist, adding reciprocal links, and adding links in the footer of other websites.
Today I checked the Domain Rating (DR) and found htryit.com's DR is 16. After consulting ChatGPT, I learned that DR is a score from Ahrefs indicating domain authority and link profile strength, ranging from 0-100. Improving DR requires optimizing external links, enhancing internal structure, monitoring low-quality links, and participating in industry activities. Therefore, I added a friend links module to the blog and quickly implemented sidebar and backend management using Windsurf, ultimately completing the friend links list page.
