Page and Brin founded Google in 1998. Google attracted a loyal following among the growing number of Internet users, who liked its simple design. 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.
The monthly volume of searches entered on keywords can be found with a few different methods. If you have a Google AdWords account, you can use Keyword Planner for this step. If you don’t, there are a few free sites out there that will give you similar numbers. Obviously, if a keyword has higher monthly searches you’ll want to keep it in mind. However, that also might mean that it has a higher keyword difficulty, and fiercer competition.
Paid or sponsored ads usually charge you for a click, while SEO doesn’t require you to pay for impressions or clicks. But do keep in mind that quality SEO isn’t exactly free. Depending on the target market you are in, you will have to invest time and money into getting the desired results. And if you’re not an SEO expert, then you would have to work with a reputable SEO company do it for you.
Search engines may penalize sites they discover using black hat methods, either by reducing their rankings or eliminating their listings from their databases altogether. Such penalties can be applied either automatically by the search engines' algorithms, or by a manual site review. One example was the February 2006 Google removal of both BMW Germany and Ricoh Germany for use of deceptive practices. Both companies, however, quickly apologized, fixed the offending pages, and were restored to Google's list.
Well, yes and no. Sure, you can get hit with an algorithm change or penalty that destroys all your traffic. However, if you have good people who know what they are doing, this is not likely to happen, and if it does, it is easy (in most cases) to get your visits back. Panda and Penguin are another story, but if you get hit by those it is typically not accidental.
