Your title tag tells both users and search engines such as Google what the topic of a particular web page is about. The <title> tag should be placed within the <head> tag of your HTML document and you should create a unique title for each page on your site.
The title above is from the homepage of our land investment website, you will see it lists the business name and main focus areas.
If your webpage appears in the search engine results page, the contents of the title tag will usually appear as the first line of the results. If you are looking to attract visitors and not cheese off the search engines then please don’t spam keywords! Keep each title relevant to the page and avoid unneeded or repeated keywords.
