Technology has moved on in most peoples lives and it relates to politics as well. Political parties know to the extent that potential voters use the internet to research policies, backgrounds and all the information they need to decide what party to support. Most large parties will now employ a seo company to handle their promotion of their policies through the internet beyond their own websites. They would be looking for articles to be published right across the web and then to be found through searches on Google. Any good seo company read more would know, that people search for what is important to them, not just say the party name.
Take for example, someone wanting to know which party will support students, it is likely that people will use Google to find that particular search term rather than scrolling through all the political sites. If you multiply tis across all the concerns of the voters, you realise how much promotion you can gain by ensuring your message is found on third party sites, or on yours. bearing in mind that the tabloids tend to be biased to one party and TV marketing is expensive and regulated, then the internet becomes the best way of delivering the political message and possibly the cheapest.
