We recently re-designed or website. During the redesign we lost a lot of homepage traffic for longtail searches, and overall low homepage secondary terms (it ranks 3rd for it's KID (previously 2). Meanwhile, our internal pages are doing just fine.
I tried doing some troubleshooting and noticed when I cut and copied a few sentences that are on our homepage and googled those sentences our website did not show up at all, although I did notice a few sites that had duplicated our entire site, spammy looking things though.
After that I went and had a coder who knows proper SEO and he went over the site for almost an hour and couldn't find any problems. We checked GWT and everything for potential problems.
I would like to add that the original coder put our homepage content on 4 published test pages and they got indexed. I have robots.txt them out a few weeks ago.
Anyways the homepage rankings are just really poor after this webdesign and just curious if anyone has ever experienced this sort of thing with bad homepage rankings and not being able to google parts of their homepage.
