I am working with a site that wants to temporarily show a promotional landing page instead of their homepage. Theoretically you could do a 302, but what are the SEO implications of doing such a thing? I would appreciate any first hand experience or feedback on the idea. Ultimately it will not be my decision, but I do have influence.
As a side note, there homepage is a mess (visually displeasing) and they really need a new website. This is one of the reasons that they are leaning this way.
Thanks in advance for the feedback.
