A good option is Drupal whose CMS can be optimized for SEO purposes and can be used not only for blogs, but as a full-fledge CMS system. So this can be implemented on corporate websites that have oftenly updated content but at the same time can be optimized well for SEO purposes.

If you are in search of an SEO Consulting company for Drupal Optimization, SEO Position seems to be promising, as they have existed for 5 years already and they also have they call Social Media Optimization (SMO)

• Wordtracker can give you related terms to a keyphrase, give you what is ore frequently searched, and also how much competition you have for a certain keyword or keyphrase. It does this by gathering data also from a list of popular search engines you can configure wordtracker to trace.
• Wordtracker can help you search for related terms by checking meta tags and also using the thesaurus built into Wordtracker.
• Wordtracker can tabulate high ranking search terms with low competition.

Although not all the best things in life are free. Wordtracker is a paid service but I personally believe their prices are still cheap once you get your first SEO client. You can start with their daily price, then go higher as your SEO clients increase. Now if you are really starting out with nothing to start with and started doing freebie jobs just to build your clientelle, SEO campaigns can still be done relatively well without Wordtracker.

Just use a few free stuff online and you can get started. Yahoo Search Marketing (formerly Overture) and Google Adwords are their respective paid advertising services. And tools made for advertisers are keyword suggestion tools that guide advertisers on what terms to target.

• Google Adwords Keyword Tool
• Yahoo Search Marketing Keyword Search

I think Google displayes the top related keyphrases searched within the previous week, while Yahoo’s tool shows you the top related keyphrases searched within the previous month. There are other tools some other people use like keyword tracker, metacrawler, dogpile and others. Some other softwares or websites with these tools are simply accessing these sites as well.

If you are really on a tight budget and the website you are doing SEO for does not have a very competitive market, Yahoo’s keyword tool will serve just fine. And a good free software that can do this for you is GoodKeywords. When not much results come in the SERPs, that means lesser websites you are competing against for the given keyphrase. Inlining this with using GoodKeywords, you can get the highly searched related keyword phrases and determine what specific phrases you will need to target. I call the GoodKeywords software Poorman’s Wordtracker.
