For some reason I had to delete some pages, these pages are using the HTML suffix, so I blocked them in robots.txt use Disallow: /*.html, but it’s been almost a year, I found that google robot often capture these pages, How can I quickly let Google completely remove these pages? And I have removed these URL from google webmaster tool by google index-> remove URLs, but Google still capture these pages.

The best way to avoid this is proactively asking the right questions. Ask about resource support. Ask about historic roadblocks. Ask to be introduced to other players who otherwise hide behind an email here and there. Ask about the company's temperature regarding a bigger SEO strategy vs. short, quick-hit campaigns. Don't be your own biggest obstacle — I've never heard of anyone getting angry about over-communication unless it paralyzes progress.
As of 2009, there are only a few large markets where Google is not the leading search engine. In most cases, when Google is not leading in a given market, it is lagging behind a local player. The most notable example markets are China, Japan, South Korea, Russia and the Czech Republic where respectively Baidu, Yahoo! Japan, Naver, Yandex and Seznam are market leaders.

This is excellent and should be intuitive for marketers (and SEO pros are marketers!) but we often take the short cut and neglect critical details. What would also reinforce the strategy is way of providing solid projections for SEO (these could be based on industry trends and statistics). Clients now ask for ways to calculate ROI and they need numbers to get budget approvals. Increase in traffic by X,  increase in qualified traffic and leads, conversions etc, some way of quatifying the expected return.
Regarding internal linking, i believe that in the case of two links pointing to an internal page, being one of those links in the group i mentioned above, they will considered only the one witch feed the algorithm with more information. In sites that have the menu before the content, it will be the second link. I think that’s the smart way for them to analyse all the links to better understand the destination page content. And they are smart 😉 .
Creating high quality content takes a significant amount of at least one of the following: time, effort, expertise, and talent/skill. Content should be factually accurate, clearly written, and comprehensive. So, for example, if you describe your page as a recipe, provide a complete recipe that is easy to follow, rather than just a set of ingredients or a basic description of the dish.
Another reason is that if you're using an image as a link, the alt text for that image will be treated similarly to the anchor text of a text link. However, we don't recommend using too many images for links in your site's navigation when text links could serve the same purpose. Lastly, optimizing your image filenames and alt text makes it easier for image search projects like Google Image Search to better understand your images.
Brian, I’ve drunk your Kool aid! Thank you for honesty and transparency – it really gives me hope. Quick question: I am beyond passionate about a niche (UFOs, extraterrestrials, free energy) and know in my bones that an authority site is a long term opportunity. The problem today is that not many products are attached to this niche and so it becomes a subscriber / info product play. However, after 25+ years as an entrepreneur with a financial background and marketing MBA, am I Internet naive to believe that my passion and creativity will win profitability in the end? The target audience is highly passionate too. Feedback?
This post and the Skycraper technique changed my mind about how I approach SEO, I’m not a marketing expert and I haven’t ranked sites that monetize really well, I’m just a guy trying to get some projects moving on and I’m not even in the marketing business so I just wanted to say that the way you write makes the information accesible, even if you’re not a native english speaker as myself.
