Elna, I love it when pro bloggers write how-to posts that are highly highly valuable to their readers. This one is top notch … as you will see by how I share my NAME and blog with this comment. What a brilliant idea that I could never have thought of on my own EVER. This one is getting pinned all over the place. I love sharing content that really helps people.
Great post. I know most of the stuff experienced people read and think “I know that already”… but actually lots of things we tend to forget even though we know them. So its always good to read those. What I liked most was the broken link solution. Not only to create a substitute for the broken link but actually going beyond that. I know some people do this as SEO technique but its actually also useful for the internet as you repair those broken links that others find somewhere else.
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.
Robots.txt is not an appropriate or effective way of blocking sensitive or confidential material. It only instructs well-behaved crawlers that the pages are not for them, but it does not prevent your server from delivering those pages to a browser that requests them. One reason is that search engines could still reference the URLs you block (showing just the URL, no title or snippet) if there happen to be links to those URLs somewhere on the Internet (like referrer logs). Also, non-compliant or rogue search engines that don't acknowledge the Robots Exclusion Standard could disobey the instructions of your robots.txt. Finally, a curious user could examine the directories or subdirectories in your robots.txt file and guess the URL of the content that you don't want seen.
You should build a website to benefit your users, and any optimization should be geared toward making the user experience better. One of those users is a search engine, which helps other users discover your content. Search Engine Optimization is about helping search engines understand and present content. Your site may be smaller or larger than our example site and offer vastly different content, but the optimization topics we discuss below should apply to sites of all sizes and types. We hope our guide gives you some fresh ideas on how to improve your website, and we'd love to hear your questions, feedback, and success stories in the Google Webmaster Help Forum1.
For example, if a swimming pool business is trying to rank for "fiberglass pools" -- which is receiving 110,000 searches per month -- this short-tail keyword can be the one that represents the overarching topic on which they want to create content. The business would then identify a series of long-tail keywords that relate to this short-tail keyword, have reasonable monthly search volume, and help to elaborate on the topic of fiberglass pools. We'll talk more about these long-tails in the next step of this process.

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?
The intent behind “SEO agency” is obvious… The searcher is looking for an SEO agency. Most of these searchers aren’t looking for life lessons from an SEO agency owner. Instead, they are just looking for the best SEO agency to get them more traffic and customers from Google. Plain and simple. I knew this when I created that page, but my SEO ego was too big.

What is the leadership like? What kind of culture do they cultivate? In smaller companies, the leaders tend to influence the culture. In larger companies, unfortunately, this can get lost. But if you have access to the leadership, spend some time learning about their vision. It should match up to the company's core values, but sometimes there are more gems locked in their minds.
When would this be useful? If your site has a blog with public commenting turned on, links within those comments could pass your reputation to pages that you may not be comfortable vouching for. Blog comment areas on pages are highly susceptible to comment spam. Nofollowing these user-added links ensures that you're not giving your page's hard-earned reputation to a spammy site.
