Sorry for my bad English since I'm not a naive speaker.
I have a small business website that run well for over 10 years, and it ranked well in Google, top 5 over the past 2 years on a specific keyword. I did everything myself, and study from here.
Half year ago, I decided to target few more keywords and hired a SEO company. They handle most of the works for me, article postings, social media, link buildings..etc. It is kind of no choice situation at that time as I have a daytime job, and other commitment in life.
The rankings ran well until last Friday's Google penguin update. My website was disappeared from Google. Only some of my articles pages get listed but not well, and my index/home page is really gone, or at least out of hundreds.
I'm trying to disavows those bad links now, and keep my finger crossed. It is kind of passive situation as I can't do anything except this, am I right?
Now I think it is better to build a new website, at least very clean profile and it is more proactive approach. I have the following questions, and hope you guys give me a light.
Shall I "copy" most of the content from my old site, or it is better to rewrite and redesign everything? As you can imagine, I have many articles written by myself and it is hard for me get a new idea to on a same topic.
In case I create a similar content of a new website, will Google "think" it is a duplication and punish my new website too?
Lastly, what happen to my old website if it get out from penalty a year later? Shall I just cancel the old domain or just let it be?
Thanks very much for reading this and hope you can give me an advice!
