Which one is for you

Pick MentionMatch if

  • Fits if you're a B2B marketer or founder who can supply quotes or data
  • Works for B2B writers who need original expert quotes

Look elsewhere if

  • Skip it if you work in consumer or general news, as requests are B2B only
  • Tight if deadlines are short, as free sources get requests a day later than API subscribers
  • Pricey if you only want requests sooner, as the API that sends them instantly is $500 a month
  • Watch out: writers are only encouraged, not required, to link to the sources they quote
  • Too light for a steady stream from any one title, as each publication can send at most three requests a week

Pick Source of Sources if

  • Fits if you want press mentions and don't want to pay anything
  • Works for journalists who need an expert quickly, since posting a query is free

Look elsewhere if

  • Skip it if you want to search or filter queries, as the site describes no search or topic filter
  • Too light for PR teams that need a dashboard, tracking or an archive of past queries
  • Watch out: one off-topic or salesy reply to a reporter gets you removed, with no appeal

Free plan and trial

    How this page was made

    • The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
    • The grades are our own, from each tool’s review or report card. The GPA is their average.
    • Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
