Some of you will already know some of the history as I've been hanging around here for a while, but I'll give a brief synopsis for clarity.
In 2005 we set up a website to support our eBay activites, and a very fine job the site did too. We made the site SE friendly, researched keywords and based new content around the most relevant/least competetive and all was going well, picking up new links and more traffic all the time.
Leading up to in March 06 we were ranking pretty well for a good number of phrases, which were bringing in respectable numbers of visitors and generating respectable numbers of conversions. Month on month our SE traffic was growing by about 8-10% and we decided the website had outgrown it's original purpose of supporting our eBay activities and needed to become an entity in it's own right. This is where the problems started!
We bought a new domain (to reflect our business name rather than our eBay user ID) and built some new parts to the site to give the visitors more to see. We added shopping facilities and expanded our range of products. We did a complete overhaul of the design, retaining pretty much all of the original content but incorporating all the new stuff too. I set up 301's on all of the old pages on the old domain, arguably a mistake considering aging delay issues, but this was 15 months ago now so all of that should have passed.
Within a few weeks traffic nosedived. After a couple of months, things with Yahoo and MSN returned as they were before - i.e. a meager but steady stream of traffic, but google sent us virtually nothing.
Things improved over the following months with Yahoo, and marginally with Goolge and MSN but nothing major happened.
We waited patiently for the aging delay to end, expecting significant improvements as none of the original content had changed and (we felt) other factors should only have been beneficial in the long term, but nothing happened, and it still hasn't. We're lucky if Google approaches 200 visitors a month right now and if we were one of those companies that relies on its search engine traffic we'd have gone out of business by now.
We've continued to promote the site, adding good content, garnering for links (albeit with some limited success),
Submitting to Directories, looking for potential blockages and removing them where possible, but other than neglegable fluctuations our SE traffic/rankings haven't improved for months.
I'm coming to the conclusion that Google just hates us, but I the only evidence I can find for that is the complete lack of reaction to everything and anything we do to try and improve things.
Can anyone make any suggestions about why this may or may not be the case and what we can do about it? I always avoid the black hat stuff and put a lot of effort into making a site worthy of our visitors attention, but as it stands the last 15 months of work on the site has been a total waste of my time. I'm seriously considering moving the site back to it's supportive role and concentrating on things that actually have some kind of result.
Oh yeah, forgot to say, virtually every page of the site is indexed, but all bar a handful of pages are in the supplementals
