An SEO technique is considered white hat if it conforms to the search engines' guidelines and involves no deception. As the search engine guidelines[18][19][52] 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,[53] although the two are not identical.
Content gaps – make an inventory of the site’s key content assets, are they lacking any foundational/cornerstone content pieces, non-existent content types, or relevant topic areas that haven’t been covered? What topics or content are missing from your competitors? Can you beat your competitors’ information-rich content assets? Useful guides on Content Gap Analysis:

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?

Create shareable content. In the world of social media, shareable content is king. Your content should be easily share-able so that your readers can spread the word for you. This is a combination of a good headline and an interesting image, as well as a captivating lead-in. All of this creates a perfect bite-sized chunk of your article that others can share through Facebook, Twitter, and other networks.[2]
Yep and sometimes it’s just being a little creative. I’ve started a little blog on seo/wordpress just for fun actually… no great content on it like here though… but because the competition is so tough in these niches I decided to take another approach. I created a few WordPress plugins that users can download for free from… and of course these link to my site so this gets me visitors each day.
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.

People love reading about results. That’s because it’s one of the best ways to learn. You can read information all day, but results show you the practical application of the information. Create content showing real life results. It’s easy in my industry because results are all that matter. But this can work in other industries as well. Here are some non-marketing examples:
Description meta tags are important because Google might use them as snippets for your pages. Note that we say "might" because Google may choose to use a relevant section of your page's visible text if it does a good job of matching up with a user's query. Adding description meta tags to each of your pages is always a good practice in case Google cannot find a good selection of text to use in the snippet. The Webmaster Central Blog has informative posts on improving snippets with better description meta tags18 and better snippets for your users19. We also have a handy Help Center article on how to create good titles and snippets20.
On one specific project, one of the SEOs on my team was brought in during the wireframe stage. T­he entire product team held SEO-specific meetings every week to go over specific recommendations, taking them very seriously, and leaning on every word our team said. We were thrilled. We were hailing their efforts, promising big wins for the relaunch, and even hyping up the launch and it’s projected SEO results in the company SEO newsletter.

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.
Nice work Laura! This is going to be a great series. I'm working my way through SEOmoz's Advanced SEO Training Series (videos) Vol. 1 & 2 to build upon the advice and guidance that you and your team provided to me during my time at Yahoo!. Now many others will benefit from your knowledge, experience and passion for SEO strategy and tactics. Best wishes for great success in your new role.

Although this is a step-by-step series, everyone's methods will (and should) vary, so it really depends on how much time you think it will take (if you're billing hourly).  What tools do you have at your disposal vs. how much researching for information will you have to do on your own? Will you have to pay for research reports or companies? Do you pay a monthly service for data or research?

If you're looking to upload an image to a blog post, for example, examine the file for its file size first. If it's anywhere in megabyte (MB) territory, even just 1 MB, it's a good idea to use an image compression tool to reduce the file size before uploading it to your blog. Sites like TinyPNG make it easy to compress images in bulk, while Google's very own Squoosh has been known to shrink image file sizes to microscopic levels.
A navigational page is a simple page on your site that displays the structure of your website, and usually consists of a hierarchical listing of the pages on your site. Visitors may visit this page if they are having problems finding pages on your site. While search engines will also visit this page, getting good crawl coverage of the pages on your site, it's mainly aimed at human visitors.
Fortunately, Google puts more weight on the anchor text of external links anyway. So as long as some of your external links have your target anchors, you’re probably OK with a “Home” button. In fact, I’ve ranked homepages with a “Home” anchor text nav button for some seriously competitive terms. So it’s not a make-or-break ranking signal by any means.
