Here's a simple way of doing it: Google will also consider text in image ALT tags. Heh heh heh. To verify, try this Google search: http://www.google.ca/search?num=100&hl=en&q=chad.jpg+b5+media&btnG=Search&meta= "chad.jpg" b5 media The #1 spot should be a page where there is an image with the ALT text chad.jpg Note that this phrase doesn't show up in the copy at all. I hope that helps! Now you don't have to worry about twisting your copy around to stuff your keywords into there.
This has got to be my #1 all time favorite spam post. Search for this unique file name and visit my site to see how great my unsolicited SEO tip is. WC, the concept is not a new one - putting keyword text in the alt tags for any images displayed within the article. The alt text is indexed and can help to identify keywords for the page. With Google's image search, the alt text is often used to identify the picture. Depending upon the site, the image search can bring a bit of traffic though it also somewhat wrongly implies that folks can make liberal use of the images. Like most things, this has been abused and if you start 'keyword stuffing' the search engines will figure it out. Used with moderation, it can be a powerful SEO tool. If the picture is of a red car, there's nothing wrong with using alt text of "red car picture" or "picture of a red mustang". Using something like, "red mustang, red car, car images, sport car, red sport car" would be frowned upon and could actually hurt your rankings.
Also, keep in mind that alt-text tags are used to describe your site to visually-impaired web users, so keep them in mind when crafting your descriptions. Also, alt-text tags have been shown to have much less value than on-page text for the reasons YMC spelled out above.
It can be useful to an extent. Keep it natural. If your keywords are centered around Hawaii real estate and vacation rentals, you don't want to put five of those keywords as alt text. You can use "Oahu vacation rental house" if it's a picture of that. It can help as long as you don't over-do it.
You shouldn't stuff keywords, IMO. You get better results when you just let your writing flow naturally.
In my experience, writing articles that are SEO should flow naturally. Considering that there are so many others trying to formulate their own writing "The Google Way" the writing is lost, and the writer is lost as well. Write good articles. It's time for us all to stop worrying so much about GOOGLE.
When I say keyword stuffing I am exaggerating... you can use this tip towards keyword density. That is not my site. Alt tags are for people who turn images off... visually impaired people don't need alt tags. They can see the picture. And if they can't see the picture, then there's no way they can read the text.
Remember, if you want to targeting a particular phrase, e.g. "is google cash a scam", then you want that phrase to appear on site at least once (or perhaps once will do). If that phrase doesn't exist in your copy, you can use ALT tags to hold that phrase without having to twist your copy around.
Yes, the writing style to achieve keywording is likely, for most people, to change their natural writing style. In my opinion, it doesn't matter... I figure most people coming to read what I write are there for the general message and a nice handy link to get them what they were really after. So they don't notice, they get what they want. Win:win. If I wanted to win awards on writing style, I'd write fiction.
Being devoted towards your writing, is the key to all "key words." remember there is no shortcuts for "good content" and if you have any shortcuts by any chance,they are going to harm you later on....
