We are running a print magazine and all issue articles are posted online as well. We optimize our Meta Titles, Meta Descriptions, and URLs for SEO but for archival purposes the actual titles of the articles are identical to what is in the print version. Many article titles are not SEO friendly. A few examples would be Fly Away or Building a Bigger Boat.How much of an impact does this have on overall SEO? Are we fine with keeping the original titles or should we change our strategy for print version titles?
