Hi Mozzers,
Would appreciate your input on this, as many people have differing views on this when asked...
We manage 2 websites for the same company (very different domains) - both sites are targeting the same primary keyword phrase, however, the user journey should incorporate both websites, and therefore the sites are very heavily cross linked - so we can easily pass a user from one site to another.
Whilst site 1 is performing well for the target keyword phrase, site 2 isn't. Site 1 is always around 2 to 3 rank, however we've only seen site 2 reach the top of page 2 in SERPs at best, despite a great deal of white hat optimisation, and is now on the decline.
There's also a trend (all be it minimal) of when site 1 improves in rank, site 2 drops.
Because the 2 sites are so heavily inter-linked could Google be treating them as one site, and therefore dropping site 2 in the SERPs, as it is in Google's interests to show different, relevant sites?
