Welcome to the Q&A Forum

Hi Annabel, OSE and other link tools may tell you if a site is linking to you, but they are not foolproof because it depends on whether those tools have indexed those links - which could take months. The best way to check if a site is linking to you is with Screaming Frog. Crawl the site you want to check and go to 'Bulk Export' > 'External Links'. This will give you a spreadsheet with all the external links on that domain and from there you can find any links to your domain. Cheers, David
