Like the title says, this is not the kind of secret that most people will hide under their moms bed because they fear that someone will steal the idea and saturate it to death. This is just a quick reminder/tip for all the newbies and experienced IM'ers. Here it is... (drum roll) WORD SPACING. Yes, word spacing, this is one of the most basic blog modifications done, especially on WordPress blogs but it is also one of the most overlooked modification. How can this help? I found out that making the word spacing "closer" than the average default number, I find it that I can read the sentences faster, because right before I finish a "word" the very edge of my eyes' vision is already seeing the next word. Here is what I mean, press CTRL(plus)+ to zoom the page once or twice like you normally do and read this example, take note that modifying word space on this forum is not possible, so I will mimic the "wrong" word spacing by doing a double space after each word. Word space of more than 1.2 px (estimate) the quick brown fox jumped over the lazy dog but the dog got angry and kicked the dog's teeth into oblivion. The normal word spacing default 1px: the quick brown fox jumped over the lazy dog but the dog got angry and kicked the dog's teeth into oblivion. of course the default is easier right? hence, the reason for it being the default But what happens when you adjust the word spacing into 0.9px or 0.8px? Yes, like I said above, even before you finish reading the phrase, for example "brown fox" the edge of your vision is already seeing the first letters of the word "over" to "the" and to "lazy". My theory is that it has something to do with our instinct to just keep on reading the sentence since the eye is not always pausing to identify the "spaces" therefore, not easily "boring" the the reader since new words are continually being provided quickly and less info about the redundant "spaces". I tried this on one of my untouched blog for 3 weeks (I used 0.8px word-spacing), and to my surprise a simple modification like this increased my CTR into my call-to-action affiliate links. And what really interested me was according to G's Analytics, the time spent by my visitors on my blog has decreased! But at the same time the people who clicks on my affiliate links INCREASED. Meaning, people are now able to read my articles faster and easier and actually finish the article, therefore, adding the chance that people will more likely click the affiliate links on my page. But of course, the conversion rate still depends on what kinds of keywords you target. For me, I promote a semi-targeted keyword on the health niche and I have top-quality articles. And yes, since the people who clicked my affiliate links increased, I also saw an increased on my CPA earnings. What I recommend is, making your font-size SLIGHTLY bigger than the average size that is being used by majority of the websites, so that even if you make the word spacing "tighter/closer" (My recommended value is around 0.9px-0.6px for word spacing) it'll still be quite easy to read. Also, this, again is one of my theory, you can call it stupid or whatever, but let's say your "potential customer" has been browsing a lot of sites for a couple of minutes/hours, and when he/she stumbles upon your site, you have the chance to capture his/her attention since the screen will "pop". Why? because the fonts on your site are bigger than the last 20 sites that he/she has visited. Not to mention, that this will also help people young/old with poor vision to easily read your texts/sales page, and people who are accessing your site through a small laptop/notebook or mobile (we all know how bothersome it is to zoom every sentence using a mobile). Remember, your site only has a couple of seconds to "tell" the user that you're not like the other 100's of affiliate sites that he/she has visited. For me, the instant "pop" alerts the potential customers' instinct to "give your site a little bit more time" because of the "uniqueness" factor. So what I recommend: *A slightly bigger font-size than most of the website uses. *A closer/tighter word-spacing than the default 1.0px The things that I said above is only PART of the many many factors of on-page optimization just like using a great theme, article quality, CPA merchant's landing page and of course keyword targeting etc... And to the newbies, I'm not saying that this is your ticket to online success. Just remember, even if you manage to rank number 1 with ten gazillion backlinks, you'll still have to convince the visitor into buying whatever it is that you're selling. But as simple as this tutorial/tip/advice might sound, I have seen results with this, and for the 5 minutes spent of going to your CSS file modifying the word spacing and font-size, it really doesn't hurt to try. This tip will be effective for short/long product review pages and for "filler articles" on your site which has a call-to-link at the middle or bottom. That is all.
