Here you go... I wrote this back in 2007.. You might know about it, you might not. But it definitely works. - Personally, I really don't care about Alexa rank. Anyways, here: Lower Your Alexa Ranking
Alexa rank is based on number of visitors with alexa toolbar installed on their browser. But why you need it? Every SEO specialist knows that Alexa ranking can easily tricked and is it not trusted source that can indicate website traffic. Anyway, engage your visitors to use Alexa toolbar.
When it comes to just numbers... its lowering... When it comes to rank....its increasing.... Thread starter has mentioned "increase ranking".... If you want to increase your SERP/SEO ranking... does it mean you want to move towards 1st in SERP ? or the other way around ?
Since alexa rankings are three months old there is no way to cheat. The gap will be shown so incresing your stats alexa stats will increase too!!
Alexa ranking is basically a statistics of how much reach your website is having in web world. More the reach will be the more you will approach towards lowering your alexa rank [the top site is google with alexa rank 1] Now how to ? Reach means how many unique visitors you are having for your site and how many search queries are generated in favour of your site in alexa. So just keep posting your website url in various social networking sites, user twitter so that people once check your site. More over in user shorter url for alexa search of such a keyword in which you are ranking in alexa SERP. Say if you are having a rank in alexa with matrimonial then short this www[]alexa[]com/search?q=matrimnonial and spread it in relevant category using social media. people will click that and as you are having a top position in serp for this they will visit your website. So just make people to click your website.
Just drive alexa toolbar traffic -- You can use the booster sites or autosurf or the ideas given above for building alexa traffic. Alexa traffic is worthless but it is nicely used when selling a site or when trying to get a glimpse as to what your site is worth in the eyes of buyers. Alexa ranking is pretty false though when it comes to having any use/worth.
I have spent money and time to develop my own original method to getter better Alexa rankings. I will not share my method for free. It is not about something black hat or illegal. The results are guaranteed and consistent unless you make a big change on your site before asking me. I will ask for either cash or a revenue share (i.e., placing a text link or banner ad on your site). I will continuously work for your site. You may PM me if you are interested. I will need to know your budget and targeted Alexa rank (what you want and what you are willing to give for it).
There is no real reason to increase your Alexa ranking. It will not really effect the amount of money you make, and it can be manipulated so it carries little weight if you are reselling your site.
As has been said, driving quality traffic to the site will increase the Alexa ranking. Try building backlinks through social bookmarking to high PR sites.
To my best knowledge and experience, installing the alexa toolbar will give small website a huge boost.Also getting your website reviewed by people in alexa will help...
