Penguin Update and Long Tail Keywords

[chuck-layton]

Since the Penguin update, organic traffic for our site; oxygenconcentratorstore.com
has dropped almost 25%.  The thing I cannot figure out is that when I compare April 1^st to May 15^th (before the update) and June 1^st to July 15^th (after); 8 of our top keywords are up. Our 2 main keywords are up 15% and 11%.

Where we lost most of our traffic is from our longtail keywords. We have almost 1000 longtail keyword phrases that we got visits from in the April/May period that we did not get in the June/July period.

Is there a reason why our top keywords would continue to improve while we most of the longtail keywords?? If Google penalized us, won’t all of our keywords be dropping and just not the longtail.

Any help/info would be awesome.

Thanks.

Many factors are involved here I see that you have allot of links anchored "oxygen concentrators" and they are on pages that have a great amount of links. Not sure what your main keywords are, however your backling profile is raising red flags IMO. I would recommend building some quality links by creating unique articles on authoritative sites. Also the Penguin update is designed to find over optimization, your sites links look unnatural (they are). It is a good practice to have the site/brand name linking in more than the other anchors.

As far as your sites rankings go maybe the competitors sites were building worse links or Google has not detected the type of links you have.

Our main keyword are "oxygen concentrator" and portable oxygen concentrator".

We had a SEO company working with us for awhile and I know they created a bunch of bad links from tons of low quality "web directories" and "blogs".

Should I try going and getting us removed from those???

Yes, however keep in mind that as you remove links you may start to lose ranking. I would recommend removing some, the ones that you can, and start focusing on getting good branded links.
