The main purpose of SEO is to make your site visible to search engines, thus leading to higher rankings in search results pages, which in turn brings more traffic to your site. And having more visitors (and above all buyers) is ultimately the goal in sites promotion. For truth's sake, SEO is only one alternative to promote your site and increase traffic – there are many other online and offline ways to do accomplish the goal of getting high traffic and reaching your target audience. We are not going to explore them in this tutorial but just keep in mind that search engines are not the only way to get visitors to your site, although they seem to be a preferable choice and a relatively easy way to do it.

1. Submitting Your Site to Search Directories, forums and special sites

After you have finished optimizing your new site, time comes to submit it to search engines. Generally, with search engines you don't have to do anything special in order to get your site included in their indices – they will come and find you. Well, it cannot be said exactly when they will visit your site for the first time and at what intervals they will visit it later but there is hardly anything that you can to do invite them. Sure, you can go to their Submit a Site pages in submit the URL of your new site but by doing this do not expect that they will hop to you right away. What is more, even if you submit your URL, most search engines reserve the right to judge whether to crawl your site or not. Anyway, here are the URLs for submitting pages in the three major search engines: Google, MSN, and Yahoo.

In addition to search engines, you may also want to have your site included in search directories as well. Although search directories also list sites that are relevant to a given topic, they are different from search engines in several aspects. First, search directories are usually maintained by humans and the sites in them are reviewed for relevancy after they have been submitted. Second, search directories do not use crawlers to get URLs, so you need to go to them and submit your site but once you do this, you can stay there forever and no more efforts on your side are necessary. Some of the most popular search directories are DMOZ and Yahoo! (the directory, not the search engine itself) and here are the URLs of their submissions pages: DMOZ and Yahoo!.

Sometimes posting a link to your site in the right forums or special sites can do miracles in terms of traffic. You need to find the forums and sites that are leaders in the fields of interest to you but generally even a simple search in Google or the other major search engines will retrieve their names. For instance, if you are a hardware freak, type “hardware forums” in the search box and in a second you will have a list of sites that are favorites to other hardware freaks. Then you need to check the sites one by one because some of them might not allow posting links to commercial sites. Posting into forums is more time-consuming than submitting to search engines but it could also be pretty rewarding.

2. Specialized Search Engines

Google, Yahoo!, and MSN are not the only search engines on Earth, nor even the only general-purpose ones. There are many other general-purpose and specialized search engines and some of them can be really helpful for reaching your target audience. You just can't imagine for how many niches specialized search engines exist – from law, to radiostations, to educational one! Some of them are actually huge sites that gather Webwide resources on a particular topic but almost all of them have sections for submitting links to external sites of interest. So, after you find the specialized search engines in your niche, go to their site and submit your URL – this could prove more trafficworthy than striving to get to the top of Google.

3. Paid Ads and Submissions

We have already mentioned some other alternatives to search engines – forums, specialized sites and search engines, search directories – but if you need to make sure that your site will be noticed, you can always resort to paid ads and submissions. Yes, paid listings are a fast and guaranteed way to appear in search results and most of the major search engines accept payment to put your URL in the Paid Links section for keywords of interest to you but you also must have in mind that users generally do not trust paid links as much as they do with the normal ones – in a sense it looks like you are bribing the search engine to place you where you can't get on your own, so think twice about the pros and cons of paying to get listed.

What are Backlinks?

In layman's terms, there are two types of links: inbound and outbound. Outbound links start from your site and lead to an external site, while inbound links or backlinks, come from an external site to yours. e.g. if cnn.com links to yourdomain.com, the link from cnn.com is a backlink (inbound) for yourdomain.com, however the link is an outbound link from cnn.com's perspective. Backlinks are among the main building blocks to good Search Engine Optimisation (SEO).

Why Backlinks Are Important

The number of backlinks is an indication of the popularity or importance of that website. Backlinks are important for SEO because some search engines like Google, give more credit to websites that have a large number of quality backlinks, and consider those websites more relevant than others in their results pages for a search query.

Therefore, when search engines calculate the relevance of a site to a keyword, they not only consider the number of backlinks to that site but also their quality. In order to determine the quality, a search engine considers the content of the sites. When backlinks to your site come from other sites, and those sites have content related to your site, these backlinks are considered more relevant to your site. If backlinks are found on sites with unrelated content, they are considered less relevant. The higher the relevance of backlinks, the greater their quality.

For example, if a webmaster has a website about how to rescue orphaned dogs, and received a backlink from another website about dogs, then that would be more relevant in a search engine's assessment than say a link from a site about car racing. Therefore, higher the relevance of the site linking back to your website, the better the quality of the backlink.

Search engines want websites to have a level playing field, and look for natural links built slowly over time. While it is fairly easy to modify your webpages to make them more SEO friendly it is a lot harder for you to influence other websites and get them to link to your website. This is the reason search engines regard backlinks as a very important factor. Further, search engine's criteria for quality backlinks has gotten even tougher, thanks to unscrupulous webmasters trying to achieve these backlinks by deceptive or sneaky techniques, such as hidden links, or automatically generated pages whose sole purpose is to provide backlinks to websites. These pages are called link farms, and they are not only disregarded by search engines, but linking to a link farm could get your site banned entirely.

Anchor Text

When a link incorporates a keyword into the text of the hyperlink, we call this anchor text. A link's anchor text may be one of the most powerful resources a webmaster has. Backlinks from multiple websites with the anchor text "orphaned dogs" would help your website rank higher for the keyword "orphaned dogs". Using your keyword is a superior way to utilize a hyperlink as against having links with words like "click here" which do not relate to your website. The 'Backlink Anchor Text Analysis Tool' is a tool which will assist you find your backlinks and the text which is being used to link to your website. If you find that your site is being linked to from another website, but the anchor text is not being utilized properly, you should request that the website change the anchor text to something which incorporates relevant keywords. This will also help boost your rankings.

Ways to Build Backlinks

Even if plenty of backlinks come to your site the natural way, additional quality backlinks are always welcome.

1 The Backlink Builder Tool

When you enter the keywords of your choice, the Backlink Builder tool gives you a list of relevent sites from where you might get some backlinks.

2 Getting Listed in Directories

If you are serious about your Web presence, getting listed in directories like DMOZ and Yahoo is a must, not only because this is a way to get some quality backlinks for free, but also because this way you are easily noticed by both search engines and potential visitors. Generally inclusion in search directories is free but the drawback is that sometimes you have to wait a couple of months before you get listed in the categories of your choice.

3 Forums and Article Directories

Generally search engines index forums so posting in forums and blogs is also a way to get quality backlinks with the anchor text you want. If the forum or blog is a respected one, a backlink is valuable. However, in some cases the forum or blog administrator can edit your post, or even delete it if it does not fit into the forum or blog policy. Also, sometimes administrators do not allow links in posts, unless they are relevant ones. In some rare cases (which are more an exception than a rule) the owner of a forum or a blog would have banned search engines from indexing it and in this case posting backlinks there is pointless.

4 RSS Feeds

You can offer RSS feeds to interested sites for free, when the other site publishes your RSS feed you will get a backlink to your site and potentially a lot of visitors, who will come to your site for more details about the headline and the abstract they read on the other site.

5 Affiliate programs

Affiliate programs are also good for getting more visitors (and buyers) and for building quality backlinks but they tend to be an expensive way because generally the affiliate commission is in the range of 10 to 30 %. But if you have an affiliate program anyway, why not use it to get some more quality backlinks?

6 News Announcements and Press Releases

Although this is hardly an everyday way to build backlinks, it is an approach that gives good results, if handled properly. There are many sites that publish news announcements and press releases for free or for a small fee . A professionally written press release about an important event can bring you many visitors and the backlink from a respected site to yours is a good boost to your SEO efforts. The tricky part is that you cannot release press releases if there is nothing newsworthy. That is why we say that news announcements and press releases are not a commodity way to build backlinks.

Link Practices That Are To Be Avoided

There is much discussion in these last few months about reciprocal linking. In the past few Google updates, reciprocal links were one of the targets of the search engine's latest filter. Many webmasters had agreed upon reciprocal link exchanges, in order to boost their site's rankings. In a link exchange, one webmaster places a link on his website that points to another webmasters website, and vice versa. Many of these links were simply not relevant, and were just discounted. So while the irrelevant backlinks were ignored, the outbound links still got counted, diluting the relevancy score of many websites. This caused a great many websites to drop off the Google map.

There is a Google patent in the works that will deal with not only the popularity of the sites being linked to, but also how trustworthy a site is that you link to from your own website. This will mean that you could get into trouble with the search engine just for linking to a bad apple.

Many webmasters have more than one website. Sometimes these websites are related, sometimes they are not. You have to also be careful about interlinking multiple websites on the same IP. If you own seven related websites, then a link to each of those websites on a page could hurt you, as it may look like to a search engine that you are trying to do something fishy. Many webmasters have tried to manipulate backlinks in this way; and too many links to sites with the same IP address is referred to as backlink bombing.

One thing is certain, interlinking sites doesn't help you from a search engine standpoint. The only reason you may want to interlink your sites in the first place might be to provide your visitors with extra resources to visit. In this case, it would probably be okay to provide visitors with a link to another of your websites, but try to keep many instances of linking to the same IP address to a bare minimum. One or two links on a page here and there probably won't hurt you.

Whenever you enter a query in a search engine and hit 'enter' you get a list of web results that contain that query term. Users normally tend to visit websites that are at the top of this list as they perceive those to be more relevant to the query. If you have ever wondered why some of these websites rank better than the others then you must know that it is because of a powerful web marketing technique called Search Engine Optimization (SEO).

SEO is a technique which helps search engines find and rank your site higher than the millions of other sites in response to a search query. SEO thus helps you get traffic from search engines.

This SEO tutorial covers all the necessary information you need to know about Search Engine Optimization - what is it, how does it work and differences in the ranking criteria of major search engines.

1. How Search Engines Work

The first basic truth you need to know to learn SEO is that search engines are not humans. While this might be obvious for everybody, the differences between how humans and search engines view web pages aren't. Unlike humans, search engines are text-driven. Although technology advances rapidly, search engines are far from intelligent creatures that can feel the beauty of a cool design or enjoy the sounds and movement in movies. Instead, search engines crawl the Web, looking at particular site items (mainly text) to get an idea what a site is about. This brief explanation is not the most precise because as we will see next, search engines perform several activities in order to deliver search results – crawling, indexing, processing, calculating relevancy, and retrieving.

First, search engines crawl the Web to see what is there. This task is performed by a piece of software, called a crawler or a spider (or Googlebot, as is the case with Google). Spiders follow links from one page to another and index everything they find on their way. Having in mind the number of pages on the Web (over 20 billion), it is impossible for a spider to visit a site daily just to see if a new page has appeared or if an existing page has been modified, sometimes crawlers may not end up visiting your site for a month or two.

What you can do is to check what a crawler sees from your site. As already mentioned, crawlers are not humans and they do not see images, Flash movies, JavaScript, frames, password-protected pages and directories, so if you have tons of these on your site, you'd better run the Spider Simulator below to see if these goodies are viewable by the spider. If they are not viewable, they will not be spidered, not indexed, not processed, etc. - in a word they will be non-existent for search engines.

After a page is crawled, the next step is to index its content. The indexed page is stored in a giant database, from where it can later be retrieved. Essentially, the process of indexing is identifying the words and expressions that best describe the page and assigning the page to particular keywords. For a human it will not be possible to process such amounts of information but generally search engines deal just fine with this task. Sometimes they might not get the meaning of a page right but if you help them by optimizing it, it will be easier for them to classify your pages correctly and for you – to get higher rankings.

When a search request comes, the search engine processes it – i.e. it compares the search string in the search request with the indexed pages in the database. Since it is likely that more than one page (practically it is millions of pages) contains the search string, the search engine starts calculating the relevancy of each of the pages in its index with the search string.

There are various algorithms to calculate relevancy. Each of these algorithms has different relative weights for common factors like keyword density, links, or metatags. That is why different search engines give different search results pages for the same search string. What is more, it is a known fact that all major search engines, like Yahoo!, Google, Bing, etc. periodically change their algorithms and if you want to keep at the top, you also need to adapt your pages to the latest changes. This is one reason (the other is your competitors) to devote permanent efforts to SEO, if you'd like to be at the top.

The last step in search engines' activity is retrieving the results. Basically, it is nothing more than simply displaying them in the browser – i.e. the endless pages of search results that are sorted from the most relevant to the least relevant sites.

2. Differences Between the Major Search Engines

Although the basic principle of operation of all search engines is the same, the minor differences between them lead to major changes in results relevancy. For different search engines different factors are important. There were times, when SEO experts joked that the algorithms of Bing are intentionally made just the opposite of those of Google. While this might have a grain of truth, it is a matter a fact that the major search engines like different stuff and if you plan to conquer more than one of them, you need to optimize carefully.

There are many examples of the differences between search engines. For instance, for Yahoo! and Bing, on-page keyword factors are of primary importance, while for Google links are very, very important. Also, for Google sites are like wine – the older, the better, while Yahoo! generally has no expressed preference towards sites and domains with tradition (i.e. older ones). Thus you might need more time till your site gets mature to be admitted to the top in Google, than in Yahoo!.
