Before buying a domain, check for penalties and blacklists to avoid inheriting a damaged reputation, email deliverability issues, or poor search engine rankings. MXToolbox
Checking a domain's blacklist status
- Email Deliverability & Spam Blacklists: Use tools like MXToolbox or ZeroBounce to scan the domain across hundreds of real-time databases (like Spamhaus and SURBL) to see if it is flagged for spam.
- Malware & Search Penalties: Visit the Google Transparency Report to check if the site has been flagged for phishing or malware.
- Comprehensive Reputation: Use Sucuri SiteCheck to verify website security and blacklist status across multiple engines.
- De-indexing Check: Perform a manual search on Google by typing (replace with the domain name). If you get zero results for an older domain, it may be de-indexed (a severe penalty). [1]
