Editorial standards & disclosures

How we write

Every guide is written to be genuinely useful and is checked against primary sources. We cite real studies and link to them. We do not publish fake author personas, invented statistics, or AI filler. When we are uncertain, we say so.

How we link out

We link to sources and tools we believe help the reader. Some outbound links to commercial tools are affiliate links, meaning we may earn a commission at no cost to you. Affiliate relationships never decide what we recommend or how we rank it, and such links carry rel="sponsored nofollow". Details, and the list of active partners, are in our affiliate disclosure.

No paid links on this site

We do not sell links, guest posts or placements on angletutoring.com, and no one pays us to be linked from an article. Our guides about buying links are reporting: they explain what links cost, the risks under Google's spam policies and how to vet a seller, for example in how to buy backlinks safely. They do not send you to a vendor that pays us.
