These days, search engine listings are placing more emphasis on incoming links to a website when looking for rank. The reason why being is because they are hard to obtain from trusted sources (a “by the book” website like the Dmoz directory) and it is a sensible way to partially eliminate the group of people who abuse the “on the page” factors of optimisation (page spamming). How is this so? Well, if you have someone who is abusing the “on the page” factors and they have no trusted links to their page (they will most likely not get any at all as a result of spam) then there is absolutely no way of them getting a good listing. However, people have worked out ways in getting a large number of links, through link farms and other tactics, whatever the quality of their website. As the search engines are aware of this, it brings us to the main topic of how one link can be better than ten.
Obtaining one link from the trusted source can be extremely difficult within the sense they usually do not issue links to merely about anyone. If you have a great website with relevant information, then you will definitely get them. It really is for that reason one link coming from a trusted source can better a multiple of links using their company websites. As this is “trusted” by search engines like google, it will also trust the websites it links to. For those who have ten links from your close friends, it will help you in a few sense, but no where near as much as the one link coming from a source like Dmoz, unless your friends features a very reputable website amongst the search engines.
Having too many irrelevant links could harm your website’s visibility in search engines like google. What exactly is meant from this has links from websites that have no regards to yours. A good example of this could be a site about cars linking to another site about medicine (unless the websites are reputable and also a valid reason for the link i.e. there exists a relationship made between cars and medicine). Search engine listings will pick up on this kind of link and definately will provide it with no weight in boosting your visibility. Obtain most of these irrelevant links, then djglva may be considered as spam (such as a link farm tactic) and will lower the buzz of your own website within search engines like google.
The real key is to focus on quality rather than quantity. Gaining several good / relevant links is going to take you much beyond lots of irrelevant links. To obtain these quality links, start off by placing your site in directories, but make sure to avoid any “on the page” spamming as this will not allow you to get accepted. Once search engines have acknowledged a presence of relevant links, followup onto it and research some ways to get more. As time passes, you will recognize that your website’s performance improves, since the links age, provided you may have performed online search engine optimisation. Avoid getting the irrelevant links although it could be tempting to see fast results. It will only be dependent on time before a search engine realises the spam tactic, and as the saying goes “fast rise”, fast fall”.
