You should fix all errors which can impair users’ expectations. By hurting user experience, you endanger the organic growth of your traffic because Google will surely limit it. Do this task thoroughly and don’t be in a hurry, otherwise, you might learn that your backlinks don’t work. Be responsible for each decision and action. Search Engine Optimization (SEO) works better when the technical optimization of your site meets the standards.
(1 - d) - The (1 – d) bit at the beginning is a bit of probability math magic so the “sum of all web pages' PageRanks will be one”: it adds in the bit lost by the d(.... It also means that if a page has no links to it (no backlinks) even then it will still get a small PR of 0.15 (i.e. 1 – 0.85). (Aside: the Google paper says “the sum of all pages” but they mean the “the normalised sum” – otherwise known as “the average” to you and me.
If (a) is correct that looks like bad news for webmasters, BUT if (b) is also correct then – because PR is ultimately calculated over the whole of the web – every page loses out relative to every other page. In other words, there is less PR on the web as a whole and, after a sufficient number of iterations in the PR calculation, normality is restored. Is this correct?
(spread across a number of pages) which lists something like 1,000 restaurants in a large city with contact details and a web link to each of those restaurant’s home page. Given that the outgoing links are relevant to my content, should I or should I not be using REL=nofollow for each link given the massive quantity of them? How will my ranking for pages containing those links and pages elsewhere on my site be affected if I do or don’t include REL=nofollow for those links? My fear is that if I don’t use REL=nofollow, Google will assume my site is just a generic directory of links (given the large number of them) and will penalize me accordingly.
An SEO technique is considered white hat if it conforms to the search engines' guidelines and involves no deception. As the search engine guidelines are not written as a series of rules or commandments, this is an important distinction to note. White hat SEO is not just about following guidelines, but is about ensuring that the content a search engine indexes and subsequently ranks is the same content a user will see. White hat advice is generally summed up as creating content for users, not for search engines, and then making that content easily accessible to the online "spider" algorithms, rather than attempting to trick the algorithm from its intended purpose. White hat SEO is in many ways similar to web development that promotes accessibility, although the two are not identical.
