Welcome to the Q&A Forum

Hi  vmotuz, Typically folks here are already working. Calls out like this may not be the best way to offer a legitimate job opportunity, especially when noting that recommended firms here are not what you're looking for. I suggest just posting your issues here and get the help of the community for free! Give you a fish, eat for a day. Teach you to fish and eat for life. Something like that. Be happy to point you in the right direction for your key words and landing pages.

Yeah, internally, "nofollow" still dilutes PageRank, so it doesn't really have a big impact. Practically speaking, I don't think there would be much difference. The links have a customer-facing purposes, I assume, and you just don't want the end result indexed. That should be fine. The only advantage to nofollow might be that it would waste a little less crawl bandwidth (instead of bots visiting the page and then seeing it's blocked, they wouldn't bother). I've tried it both ways in the past (after Google changed the PR-sculpting rules), and could never really measure much difference.

Hi Vitaly A good question.  There are usually 2 main considerations when it comes to cross-linking sites: To benefit the visitor from pointing to a useful related site To try and aid SEO/Search efforts. Your goal of trying to improve rankings of the newer sites by linking your hotel booking sites together could be counter-productive. Cross-linking sites with the intention of trying to improve search rankings (through the passing of link juice through the said links) usually has a short-term gain, then either neutral or negative. It's a risky game in trying to 'manipulate' search rankings by linking a load of sites together, which being honest is just what this would be. With regards to the other reason for doing so, providing links that visitors could find useful, that's a sound and credible reason to link the sites together, just play it safe and NoFollow the links as Ben suggests. This would be playing it by the rules and keep the search engines happy whilst also benefiting your visitors. Have you considered migrating your websites into one large site to serve all cities? Done properly, always with the visitor experience & offering in mind, it can benefit everyone.  You'd only have the one website to create content for and get links into, whilst providing one more in-depth offering and experience to your visitors.  Worth considering anyway, local search can still be catered for with one large website. Kind regards Simon
