APA Style (7th ed.)

Sometimes you need to go into more detail about one particular source. Putting an in-text citation after every sentence that comes from that source doesn’t look great and breaks the flow of your writing, but leaving the in-text citations out risks plagiarism. So, introduce the source early in the paragraph, with the author as part of the sentence rather than in brackets:

Wixom and Ross (2017) describe how companies can monetize their data.

For the rest of the paragraph, you can refer back to the author by name or pronoun when elaborating on their ideas:

They explain how using the abundance of data available to their advantage will ultimately make a profit for them and stand out as a competitor. Wixom and Ross also found that …

To indicate that the ideas in a new sentence come from the same material as the previous sentence, phrases such as the following should be added such as:

The author goes on to say that …
The authors also mention that …
He concludes that …
She believes that …

If it is clear to the reader that all the ideas come from that same source, there is no risk of plagiarism and the paragraph flows well.
