When writing an article, does Google and the other search engines recognize the difference between upper/lower case keywords? Reason asking is that some webmasters want a keyword or keyword phrase to be capitalized within the body of the article, even if it doesn't make sense to do so.
I really wanted some opinions regarding my question, not only people just interested in driving up post counts.
My answer is no.. You can capitalize your keyword to get attention of visitors.. but for google it is only a keyword.. If you make certain keyword as Bold and capital it does not mean it is more important of your site and not others.. My recommendation is concentrate more on quality and important keyword.. you may use wordtrack to get keyword suggestion.
I think the previous posters were answering your question. Google spends a great deal of time analysing which sites are better than others. Surely good grammar and layout must be a factor in deciding which are reputable sites. If they don't, most readers would when they visit your pages. I guess that the webmaster want to use capitals in the belief that this draws the human eye. In some cases it does assuming that it's relevant and not over-used @Bluebelt91 - Google does recognise bold font in the same way as it recognises heading tags, but their over-use could see a negative effect.
Google takes no notice of capitalisation, it is only beneficial to how the text reads on a page. If google did take notice then many keywords would have to be repeated to be correct such as "Money, money, Surveys, surveys." this would be hugely duplicitous and a waste of processing time for google bots.
