While you are trying to optimise your site so that it can rank better for certain keywords in Google, there are a few very important on page factors that can play a vital role. You can determine that three of them are the most crucial apart from the design and the content on the site.
The first factor that is very important for Google optimisation is the Title. These tags are usually found on top of your browser. In addition, when you search for a keyword on Google, you will find that the results are displayed with the title. This emphasises on the importance of such tags to Google and therefore you must be sure that you can include your main keywords out there. In addition, a great strategy is to create keyword based title tags for pages that have already been indexed as this will help you to rank higher for the keywords faster.
Meta Description & Tags
After the implementation of the title tags, the meta description and the meta tags are very important. You'll find that beneath each title tag in the search results on Google, you will find some text with keywords highlighted. In most cases it is the meta description. Such a description is an indication to the search engines regarding the relevance of the content on the site. Along with the meta description, you should also mention the meta tags, these are basically an indication of the keywords that a specific page is targeting to be optimised for.
The headers and sub headers in your content are very important for your Google optimisation purpose. These are often referred to as the header tags and have to be aptly placed with the keywords. Google as a search engines, rates such header very highly and if correctly placed you can be sure that they can get you a lot of good results. Google optimisation will become a lot easier with these tags added to your content.
Other than the above mentioned tags the alt and the image tags are two other important tags that need to be taken into account. Once you have all these in place, Google optimisation will become a lot easier that it would have otherwise been. Just make sure that you can have the right keywords at the right spot so that the density remains within a limit and the page would not be considered for keyword stuffing.
