Why not just make the alt text the name of your company? That is the point of alt text after all... ;)
Hi, welcome to the board!
Having parts of pages, like headers, footer, nav bars consistent throughout the site is good usability practice.
For the same picture you should use the same alt txt, as it's main function is to substitute the picture of users who can't or won't see the pictures.
Just avoid stuffing the alt txts with long winded lists of keywords, as that will have little to no effect, decrease the usability value, and make you a perfect target for the competition to file a Google Spam report.
Hi and thanks for the welcome. To clarify, since my logo is indeed at the top of each page, I guess I'm a little concerned about having the same phrase at the top of each page as well in the alt tag...
I run 5 sites, and they rank well enough where I would be concerned to drop in rankings. But I put alt tags in several years ago and I made them different for each occurrence of the logo on each page of each site. So I guess I am afraid that it could be considered spam if I now change the logo alt tag on every page to the same phrase such as, "Company Name's Yummy Product" or
"Company Name's Certain Type of Service" as it would look like I am just putting the same name and keyword at the top of each page.
Then again, if I were Google, I would probably consider it spam if a site did the oppsoite and had a different alt tag for each occurrence of the same company logo on every page of the site (which is the way I have it now).
Do you have a company tag line? Like "Widgets INC - the widgetizers"? Put that in all instances, would be my recommendation.
You should not forget though alt txt is not worth much if any ranking wise.
Let's pretend ....
(a) I just wiped away all your graphics and you can't get them back.
(b) Your password isn't working and you can't change the alt tags on your site before Monday.
(c) This is a prime online shopping weekend.
(d) For each missing graphic, the assigned alt tag is all that is visible.
Will your alt tag assist your users this weekend? Or, are your alt tags a garish jumble of spider buffet keywords?
So, do you frantically want your graphics back, or are you feeling fairly comfortable with your alt tags?
What I have done is name each site "So and So's Product" or "So and So's Service", and the company logo is a graphic design that displays each site name in that way -- "So and So's Service".
So I could make the alt tag for each occurrence of the logo say "So and So's Service" as well.
Maybe I will try doing this on one site and see if it affects my ranking. Hopefully it won't mean much as the alt tag doesn't count for much as you said. Then I can have the proper alt tag to correcly describe the logo when it appears on every page.
Thanks for your help.
I have a page with very little text and a lot of graphical links. Moved up in rankings when I added alt text to links, The text in many show up in site's description and they do add key word value.
