I assume you are trying to compare something like the "clicks" from your paid search tool, and visits from the Adobe side...
Have you fully configured Adobe to properly recognize "paid search"?
Please check:
Admin > Report Suites > (select report suite) > Edit Settings > General > Paid Search Detection
Make sure that you properly configure all your paid search parameters here.
If this is set up, and set up properly, can you provide more information about what issues you are seeing?
Also note, if you are looking at Marketing Channels "Paid Search", the default attribution is 30 days (direct traffic does not overwrite a specific channel)... so if you are comparing clicks (which are hit level) to 30 Day attribution on visits, you really aren't comparing apples to apples.
