Page and Brin founded Google in 1998.[22] Google attracted a loyal following among the growing number of Internet users, who liked its simple design.[23] Off-page factors (such as PageRank and hyperlink analysis) were considered as well as on-page factors (such as keyword frequency, meta tags, headings, links and site structure) to enable Google to avoid the kind of manipulation seen in search engines that only considered on-page factors for their rankings. Although PageRank was more difficult to game, webmasters had already developed link building tools and schemes to influence the Inktomi search engine, and these methods proved similarly applicable to gaming PageRank. Many sites focused on exchanging, buying, and selling links, often on a massive scale. Some of these schemes, or link farms, involved the creation of thousands of sites for the sole purpose of link spamming.[24]
At the retail level, the two top organic food sales categories, receive significant price premiums over conventionally grown products. ERS also analyzed organic prices for 18 fruits and 19 vegetables using 2005 data on produce purchases, and found that the organic premium as a share of the corresponding conventional price was less than 30 percent for over two-thirds of the items. The premium for only one item—blueberries—exceeded 100 percent. In contrast, in 2006, organic price premiums for a half-gallon container of milk ranged from 60 percent for private-label organic milk above branded conventional milk to 109 percent for branded organic milk above private-label conventional milk. See the ERS report for more on this topic:
Paid search advertising has not been without controversy and the issue of how search engines present advertising on their search result pages has been the target of a series of studies and reports[23][24][25] by Consumer Reports WebWatch. The Federal Trade Commission (FTC) also issued a letter[26] in 2002 about the importance of disclosure of paid advertising on search engines, in response to a complaint from Commercial Alert, a consumer advocacy group with ties to Ralph Nader.

Very interesting video! In my case I am faced with the problem that my company supplies tools throughout my country, but I see that we have only a very good local SEO positioning, I do not know how to tell Google that my company is interested in appearing in the results of the whole country, not only in my neighborhood :-( !! ... sorry for my poor English.

This refers to your ability to rank for certain keywords. For instance, say you sell shoes online, you will need to optimize your site, backlinks, website speed and much more so that you can “rank” high for certain keywords that are highly relevant to your business. Relevant keywords may include “buy shoes,” “shoe sale,” “where to buy shoes,” and so on. Once you can rank high (top page) for these keywords, you will enjoy an increase in traffic and business as a result.
In addition to helping you find keywords you should be bidding on, thorough keyword research can also help you identify negative keywords – search terms that you should exclude from your campaigns. Negative keywords aren’t terms with negative connotations, but rather irrelevant terms that are highly unlikely to result in conversions. For example, if you sell ice cream, you might want to exclude the keyword “ice cream recipes”, as users searching for ice cream recipes are unlikely to be in the market for your product.
Every new blog post that you publish gives you an opportunity to spread it through social media, which helps to drive more traffic back to your site. Use your blog as a way to connect with your audience. Your blog isn’t a place to just post overly promotional posts. This is an opportunity to address possible concerns or even common questions related to your service or product. If you are worried about coming up with enough content ideas to publish blog posts on a regular basis then check out these resources:
Guest blogging purely for inbound links is a flawed strategy because the value of those links are going down. However, guest blogging for traffic is still an incredibly viable strategy. While that inbound link you get at the end of a guest post doesn’t have as much SEO value as it used to, it still has the value of exposing your content to a new audience.

Writing blogs for your website not only helps with organic search engine optimization, but it provides valuable information for your potential customers and website visitors, among other things. Writing blogs about the industry you service will provide a place for you to insert your keywords plenty of times, while keeping the information relevant and helpful. On top of that, it makes your business look like an industry expert. A well-written blog makes you look more credible because of your level of expertise. Blogs that optimize for keywords will ideally be anywhere from 500 to 2,000 words, but not everyone has the time to crank out blogs that size every week. However, posting shorter blogs still provides value to your client base and potential customers.
Remember when you used to rely solely on search engines for traffic? Remember when you worked on SEO and lived and died by your placement in Google? Were you #1? Assured success. Well, okay, maybe not assured. Success only came if the keywords were relevant to your site users, but it was the only real roadmap to generating site traffic and revenue.
