Hi All
I have written some article for my site and posted it to various sites. But the content of that article is same as the content on the news page of my sites. Does google will consider it as spam?
Secondly, does ALT tags has lost its importance in SEO? I have seen one site using ALT tags like "", "". Does this have some special relevance? And does overuse of ALT tage is considered as spam?
Somewhere, I read that making blogs for a site could be bad. Is this true? What are the relevance of blogs in SEO?
Please help.
Thanks.

Google does not consider that as spam, if you posted your articles elsewhere too. I hope you have posted them on your own site first and was first crawled by Google, otherwise you will not get PR for them.
About "alt" attributes read this:
An alt attribute is not a label or description for the image. This is
not an immediately obvious distinction. In fact, it might seem natural
to assume that alternate text is a label or a description. It is not.
The words used should be a text equivalent and convey the same
information/serve the same purpose as the image. The aim is to provide
the same functional information that the visual user sees. The alt text
should be a "stand in" if you will if the image is missing. The test
is, when you replace the image with the text would everyone do the same
thing/receive the same information as best as possible?
Some examples:
- If a search button is a magnifying glass or binoculars its alt
text should be 'search' or 'find' not 'magnifying glass' or
'binoculars'.
- If an image is meant to convey an image - then a description is appropriate.
- If it is meant to convey data - then that is what is appropriate.
- If it is meant to convey a function then that is what should be there.
Some Alt Attribute Guidelines:
- Always add alt attributes to images. Alt is mandatory for accessibility and for valid (X)HTML.
- For images that play only a decorative role in the page use an
empty alt (i.e. alt="") or a CSS background image so that reading
browsers do not bother users by uttering things like "spacer image".
- Remember it is the function of the image we are trying to
convey. For instance any button images should not include the word
"button" in the alt text. They should emphasize the action performed by
the button.
- Alt text should be determined by context. The same image in a different context may need drastically different alt text.
- Try to flow alt text with the rest of the text because that is
how it will be read with adaptive technologies like screen readers.
Someone listening to your page should hardly be aware that there is a
graphic there.
It is useful to categorize non-text content into three levels:
1. Eye-Candy:
Eye-Candy are things that serve no purpose other than to make a
site visually appealing/attractive and (in many cases) satisfy the
marketing departments. There is no content value (though there may be
value to a sighted user). Never alt-ify eye-candy unless there is
something there which will enhance the usability of the site for
someone using a non-visual user agent. Use a null alt attribute or
background images in CSS for eye-candy.
2. Mood-Setting:
This is the middle layer of graphics which may serve to set the
mood or set the stage as it were. These graphics are not direct content
and may not be considered essential, but they are important in that
they help frame what is going on. Try to alt-ify the second group as
makes sense and is relevant. There may be times when doing so may be
annoying or detrimental to other users. Then try to avoid it. For
instance ALT text that is identical to an adjacent text is unnecessary,
and an irritant to screen reader users. I recommend alt="" or
background CSS images in such cases. But sometimes, it's important to
get this content in there for all users. Most times it depends on
context. The same image in a different context may need drastically
different alt text. Obviously, content should always be fully
available. The way you go in this case is a judgement call.
3. Content/Function:
This is where the image is the actual content. Always alt-ify
content and functional images. Title and long description attributes
may also be in order.
The reason many authors can't figure out why their alt text isn't
working is that they don't know why the images are there. You need to
figured out exactly what function an image serves. Think about what it
is about the image that's important to the page's intended audience.
Every graphic has a reason for being on that page: because it either
enhances the theme/ mood/ atmosphere or it is critical to what the page
is trying to explain. Knowing what the image is for makes alt text
easier to write. And practice writing them definitely helps.
A way to check the usefulness of alternative text is to imagine
reading the page over the telephone to someone. What would you say when
encountering a particular image to make the page understandable to the
listener?
Besides the alt attribute you have a couple more tools at your disposal for images.
First, in degree of descriptiveness title is in between alt and
longdesc. It adds useful information and can add flavor. The title
attribute is optionally rendered by the user agent. Remember they are
invisible and not shown as a "tooltip" when focus is received via the
keyboard. (So much for device independence). So use the title attribute
only for advisory information.
Second, the longdesc attribute points to the URL of a full
description of an image. If the information contained in an image is
important to the meaning of the page (i.e. some important content would
be lost if the image was removed), a longer description than the "alt"
attribute can reasonably display should be used. It can provide for
rich, expressive documentation of a visual image. It should be used
when alt and title are insufficient to embody the visual qualities of
an image. As Clark [1] states, "A longdesc is a long description of an
image...The aim is to use any length of description necessary to impart
the details of the graphic. It would not be remiss to hope that a long
description conjures an image - the image - in the mind's eye, an
analogy that holds true even for the totally blind."
Although the alt attribute is mandatory for accessibility and for
valid (X)HTML, not all images need alternative text, long descriptions,
or titles. In many cases, you are better off just going with your gut
instinct -- if it's not necessary to include it, and if you don't have
a strong urge to do it, don't add that longdesc. However, if it's
necessary for the whole page to work, then you have to add the alt text
(or title or longdesc).
What's necessary and what's not depends a lot on the function of
your image and its context on the page. The same image may require alt
text (or title or longdesc) in one spot, but not in another. If an
image provides absolutely no content or functional information alt=""
or background CSS images may be appropriate to use. But if the image
provides content or adds functional information an alt would be
required and maybe even a long description would be in order. In many
cases this type of thing is a judgement call.
