Hello,
Back Story
I have a client (law firm) who has a large .html website. He has been doing his own SEO for years and it shows. I think the only reason he reached out to a professional is because he got a huge penalty from Google last fall and fell very far down in rankings. Although, he still retains a #1 spot in Yahoo for his site for the keyword phrase he wants.
I have been creating a new WordPress theme for the client and creating all new pages and updating the formatting/SEO. From the beginning I have told the client that when we delete the old site and install a new WordPress site (same domain name, but different page hierarchy) he will take a bump in the search engines until all the 301 redirects get sorted out. I told him I can't guarantee any time frame of how long the dip in SEO will last. Some sites bounce right back while others take longer.
Last week, during a discussion, he tells me that if he loses his #1 ranking on Yahoo for any length of time he thinks he will go out of business. Needless to say I was a little taken back. When it comes to SEO I use best practice techniques, do my research, stay on top of trends but I never guarantee rankings when moving to a new site.
I'm thinking of ways I can help elevate any type of huge SEO drop off and help the client. Here is what I was thinking of suggesting to the client and I would love some feedback.
Main Question
He has another domain he isn't doing anything with. It's pretty much his domain name with pc added. I was thinking about using that domain to create a simple 1-2 page WordPress website with brand new content (no duplicate content) aimed at attracting his keyword phrase. I would do as much SEO as I could with a 1-2 page site and give it a month or so to see if this smaller site can get into the top #10 in Yahoo, or higher. Then, when we move the site he will still have a website on the first page of Yahoo for his keyword phrase.
I hope I explained it clearly
I would be open to any suggestions anyone may have. Thanks
