Old domains can be good value, especially if you know their history which it sounds like you do. The biggest issue with old domains is tracking their history and making sure bona fides.

Is the old domain re-vamp consistent with previous domain use at all. ie  the backlinks and anchor text relevant in any way?

Below is a copy and paste of keywords relating to Arvixe obtained from Semrush. You should check them.  Coupon is very competitive, so I have skipped that. So I would suggest:-

Arvixe Hosting Review | Arvixe Coupon | Sitegeek

or

Arvixe Hosting Review | Arvixe Uptime Report | Sitegeek

You should include your brand name as google usually will do regardless. It really is a personal decision as you know your brand / company best. Hope this helps.

The word Arvixe - would not be highly competitive - so need to use that 3 times. Coupons is competitive.

The below is the title that appears if I google Arvixe

Web Hosting | Shared Hosting | Website Hosting by Arvixe

Are you changing the Title to the home page or is it a new page? The Coupon page? The most common search term according to Semrush is "Arvixe Coupon".  The above suggestions appear to be targeting 3 different topics rather than one broadly, like your current title.  Need some more info on what page you are targeting and why - otherwise could be leading you down the garden path.

You are always right... so I got confused!  All good...

The company I work for specializes in CTR on search results - we run complex experiments on them ie 30-40 today alone. There is a difference between pipes and hyphens on CTR.  It is small but it is statistically significant. Sure it is irrelevant to most but for big boys chasing keywords like "car insurance" etc it is vital as each click is has such high cost in competitive spaces.

Matt Cutts noted the CTR factor between them as well. I do not believe it makes any difference on SEO except in so far as it uses more pixels.  So maybe we agree, but a clean tidy looking title that looks professional to the customer does have an impact on CTR.

We do alot of experiments for clients on the difference between pipes, colons and hyphens.

99 out of 100 the pipe is the preferred separator.  Generally the pipe is best for both SEO and Clickability.   This is as the pipe also uses less pixels. Recommend as follows:-

Most Important Key Word | Second Keyword | Brandname ( no more than 512 pixels in length or otherwise it truncates).

If you detail a couple of options I can probably tell you what is likely best.
