As stated here:
As also indicated there, you can use the noframes tag (not supported in HTML5) to provide alternative content that search engines can use to index the iFrame with.
IFrames also support Global Attributes, including the title attribute which can be used to add keywords for the iFrame, just like anchor text in a link. You can also add them to a longer description in the longdesc attribute (also not supported in HTML5). Using these attributes may also help get the iFrame indexed on the customer's page.
You should also add a canonical URL in the page on your site that points to the customer's page so that search engines might consider that as the page to index, and you should add a disallow directive in your robots.txt file to tell robots not to index the URL of the page on your site.
Combing the above with additional content on the customer's page that's relevant to the terms that search engine users might search for, will improve your chances that your customer's page will be indexed and found in searches.
