Welcome to the Q&A Forum

For the last few years I've been gaining steady backlinks for my clients by producing online press releases for them (e.g. publishing results of a survey they commissioned, or their expert opinion on recent news, etc). The online coverage included a backlink naturally or by me just asking the publication nicely.  But recently I'm finding that publications are asking for a fee to publish the article (with a link) or they will publish the article for free, but will add a link for a fee.  Note: these publications aren't link-building-sites, they're good DA sites such as  https://www.femalefirst.co.uk/ and  https://www.moneymagpie.com/  (MOZ DAs of 80 and 56 respectively). The fees are around $200 each. The clients can afford to pay for this type of coverage, but is there a risk in these cases with Google?
