Selecting a correct, proper and related keyword for your web site is key and most important as far as SEO is concerned. Selecting proper keywords is the base of the search engine optimization campaign. In other words it is the foundation of the search engine optimization campaign. At this stage, think many times and look around in the top search engines and/or use keyword selection tools to create a list of related keywords not only for your home page but every single page of your website.
During Selection of Keywords, make sure of following considerations:
First of all, select domain name which reflects the theme of your web site (if it is possible), however, if it is not applicable to get the related domain name then consider another, because it is not very important because most of search engines don’t give weight to the URLs.
Select keyword which are specifically related to your product or services you are going to offer. If you are using keywords in phrases then these must be meaningful short sentences, otherwise, yes your site will appear in top positions but there will be no use if no one is using that unnatural keyword phrase on the net. That means the keyword should be selected as per your product and services in meaningful short phrases.
If it is applicable, regionalize your keywords, because targeting on regionalized market will result more useful and targeted traffic with lower competition, in fact there will be more sales. For example, if you are selling product or service in Las Vegas, Nevada, then add Las Vegas or Nevada in your selected key phrases.
Select relatively less competitive keywords which will increase the probabilities of appearance of your site in top rankings.
After these considerations, you will find a good comprehensive list of keywords; now you can professionally and effectively optimize your entire site for all of your selected keywords, if you have series of landing pages with various services and products.
Another term which has very significant role in search engine optimization is Anchor Text; it has importance within inbound links. Inbound links from websites provides your site two benefits. The first and obvious is that these links can help your company by sending potential customers to your website. The second benefit is that Google and the other major search engines will see these links as votes of confidence therefore giving your website a boost in its rankings. When developing inbound links it is important to take advantage of keywords that your site might be targeting.
In the First paragraph I mentioned that you need keywords not only for your home page but for your other pages as well, it has paramount importance that your optimization efforts should never stop after your home page is completed, your entire site should be professionally optimized for maximum results.
At the last but not least, do not make mistake in selecting higher competitive keywords, this will lead your website dropping in deep pages of search engine results.
