Hotel SEO Factors

On-site SEO factors-

• Use hyphens or commas as “Page Title” or header separators - not underscores. 
• If possible use a file extension (.html) or at least have mime type to help Google and also users.
• You can “unleash” hundreds of pages (obviously all with great content) at once with no penalty -thousands of new pages, however, “may” flag up for review. 
• A HTML Sitemap is still recommended by Google for googlebots & for users. 
• Google does not “penalise” duplicate content - it will just show one page over another.  If there are 3 pages of duplicate content on your website it generally will only show 1 result on a Google results page, (unless the search is incredibly longtail and specific – but of course we now get the “omitted results” link displayed). Google just shows the content that it feels is most relevant to the users search. New algorithms take into account things like content age (so original content is more likely to rank higher). (Greg gives the best explanation, not Matt) 
• A webpage being 4 levels down in the URL (example.com/some-news/2011/march/a-great-news-article.htm) is just as valuable as a webpage 1 level down (example.com/a-great-news-article.htm) IF linked to from a top level page. 
• In SEO terms,“example.com/tools/hammers/a-great-hammer” is no different than having  ”example.com/tools-hammer-a-great-hammer”. In user terms, however, it can start to look spammy to have multiple keywords separated by a hyphen. 
• “Read More” dropdowns CAN be seen as hidden text (blackhat) if large areas of text are hidden with only a small area of visible text. If there are reams and reams of text hidden below a javascript/accordion type button with only a few words always visible then it will show as being hidden text to Google. Instead use tabs to show as much content as possible that switches with tabbed buttons. 
• Using the visitors IP address to change the title & heading to the local language/dialect is perfectly acceptable. Geo-location content is not classed as content cloaking. 
• It is better to have keywords in the URL as it is taken as a factor in the ranking results, albeit only one of over 200. 

Links and off-site factors

• Google will not penalise a website that uses the “no follow” attribute on all of its outbound links – 
• On-site links are no longer restricted to 100 links per page (as Google guidelines used to state). It is perfectly reasonable to have more if the page and site is rich in content. Common sense is needed, however, as 1000′s of links on a page could indicate a link farm. Also keep in mind that pagerank on a page is divided out to the links on the page (a PR4 page with 40 links will mean each link gets a 1/40th chunk of the PR) so it may be beneficial to have only important pages linked to from a high PR site. 
• Links at the bottom of the page are treated differently than ones at the top or within the content body.
• The amount of 301 redirects to a domain will not penalise you. 301 redirects carry link text (anchor text) but if there are too many new links being generated to a 301 redirected URL it could look shady.
