[HELP!] File Name and ALT Tags
-
Hi, please answer my questions:
1. Is it okay to use the same keyword on both file name and alt tags when inserting an image?
Example:
File Name: buy-lego-online.jpg
ALT tag: buy-lego-online
Will it trigger Google Panda? Will I be penalized for that? Or the file name and alt tags should be different from each other? Because when inserting an image on Wordpress, the alt tags are always the same as the file name by default.
2. For example, I have 2 images in a page (same topic/niche) and I will put "cheap-lego-for-kids" and "best-lego-for-sale" as alt tags. Considering that I repeat the word "lego", is it considered keyword stuffing? Will I be penalized for that?
Thanks in advance!

I know this is like beating a dead horse, but thought I would link to Search Metric's 2014 ranking factors study. What is missing in what they see as factors that increase rank is ALT tags on images.
You can see the infographic below, you can also download the 80+ page report which I would highly recommend

Using a word twice on a page is indeed, not keyword stuffing - where did I say that it was??? I don't believe I have EVER said that in all the years I've worked in digital marketing!
I said that using the same alt tag would be spammy - the reason I think that is that it either implies that you don't have unique images on the page (so what's the point of them?) or that you have been lazy with your alt tags by repeating the same one over again. Both bad user experiences for folk that need them.

Hi Amelia, you're right about that alt tags are for people who use screenreaders. Though search engines like google also use the alt tag to recognize there is an image file.
The alt tag is an onpage factor that influence ranking (http://a-moz.groupbuyseo.org/learn/seo/on-page-factors)
Although the alt tag may looks like as not important, it's worth using it.
About the spammy thing, using a word twice on a page has nothing to do with keywordstuffing

Grtz, Leonie

Hey Amelia.
Yes you are absolutely correct, alt tags are for people, and should be used to that end. When I said it 'tells' Google what the images is about I was responding directly to Shawn's comment that ALT tags are for accessibility, not SEO...
Technically yes, but Google does use the alt text as a relevancy signal (at least as far as we know). And ranks your image (in Google images) based primarily on that information. It’s a part of SEO for better or worse. Besides, you can both improve your on-page AND give relevant and meaningful info to the user, i've never had to choose. If it came down to it I’d always prioritize the user.

Amen Amelia. I said the same, but not nearly as thorough as you did.

Hi,
I just wanted to dispel a few myths going on here...
- ALT tags are NOT to 'Tell Google' what the image is about, they are there for people who use screen readers to enrich their use of the internet.
- Screen readers can be set up to read out alt tags, file names or title attributes - depending on the user's preference and presumably on the site they are looking at
- Google can and does read image file names: http://blog.hubspot.com/blog/tabid/6307/bid/32567/A-Marketer-s-Guide-to-Optimizing-Images-for-Google-Search.aspx
If you pick relevant images for your pages then you probably will be able to get keywords into both the alt tag and the file name. I don't think this is spammy! It's accurate.
What would be spammy, and this has already been covered by Issac, is if you repeat the same alt text on the same page - vary it! - 'Blue lego bricks' etc. I personally would avoid saying stuff like 'cheap', 'buy' etc UNLESS the image has that text within it (say a picture of lego with a headline within the image saying 'cheap lego') in which case you are doing exactly what the alt tag is there for - enabling screen reader users to experience as similar experience to us sighted folk as possible.
Sorry for the rant, but it annoys me that something that is meant to help people who are (to my mind) at a disadvantage is abused for SEO purposes!
Best wishes,
Amelia
**EDIT: I am well aware that Google and other search engines use alt tags for rankings. What I wanted the OP to be mindful of is that alt tags were not invented 'to tell google what an image is about'. And to point out their value and use for people using screen readers. Most people do not fully understand how blind users navigate the inter-webs, me included. I just think if I can do something to make it easier for them then I will. If you'd prefer to write alt tags purely for the search engines, that is entirely your prerogative! **

No you won't be penalised for that.
But do check out my initial response below for a more detailed answer.

Thanks so much, Isaac! Sorry for the newbie question. For you, is it okay to use the same file name and alt tags in an image?
For example:
File name: cheap-lego-for-kids.jpg
Alt tag: Cheap Lego for Kids
Will I be penalized for this?
-
A space between each word

Think of the user. Some poeple don't have their images active when useing the web. What would they want to see?
Isaac.

Hi Mai.
You should be fine with the example you give. So long as you don't just repeat 'lego for kids’ over and over on the page!
Just add your keywords into natural writing style that your users will find usefull and infomative.Alt tags are useful for SEO. They 'tell' Google what the image is all about. The images and the alt text should be relevant to what's on your page. So I hope your page is about lego products

Alt tags also makes your images more likely to rank in Google images for relevent keyword searches. This is becoming more popular with people who like to scan through products visually.
Hope that helps.
Isaac.
-
Thank you very much! Last question, which one is better to use on alt tags?
SPACE or HYPHEN? Cheap Lego for Kids or cheap-lego-for-kids?
Thanks again!

ALT tags are for accessibility, not SEO. Screen readers will look at those tags and read to those that have trouble with seeing the page what the image is.
As long as the ALT tags are accurate representations of what the image is, you should be okay. If you are attempting to stuff keywords into ALT tags and they do not accurately describe what the image is, then you may not receive any benefit and could potentially get some kind of penalty.
-
Hi, Google can't read (yet) image filenames, that's why we use the alt tag, to tell google what's the image is about. So you can use the image file name as alt tag, no problem. If you use the word "lego" twice it's not keyword stuffing.
here's something to read about keyword stuffing: http://a-moz.groupbuyseo.org/community/q/what-constitutes-keyword-stuffing

What heading tag to use on sidebars and footers
Hello, I have some awareness of how to use H1, H2 and H3.
On-Page Optimization | | kowston
H1 only once per page as the main page heading.
H2's should be subheadings, H3's are sub-sub headings of the and so on.
This structure gives hierarchy and opportunities to use additional keywords in an order of priority. I can clearly understand how this would work in an article but what about other content on the page such as global/frequently repeated elements like sidebars and footers? I see sites - and in particular, I have examed SEO focused sites - that use H3, H4 and H5 in these instances seemingly giving themselves scope to use at least H2 tags as part of the page content and break out of the structure hierarchy when dealing with sidebars and footers. I suppose this could signal theses headings are sections of the page that are less relevant than the main article content but that is just an assumption. I don't know what is correct.0 -

Issues with Multiple H1 tags on homepage?
Hi folks, My homepage has 3 identical H1 tags due to the fact that I have had to create individual hero images (with headings) for desktop, tablet and mobile. I couldn't get my theme to display the layout in exactly the way I wanted on each device without doing a specific hero image and tag for each device type. Does this have a major impact on my SEO? Thanks,

Adding Tags in the blog is good or bad?
Hi Friends, In my blog I used to write unique content in between 300 to 450 words and add the related tags up to 15. When I research about adding tags in the blog I come across this video from “Matt Cutts” says Is it worth spending time on creating tags and categories? http://www.youtube.com/watch?v=A96yDPqa2rs Key Points from Matt Cutts Video are given below: No Need Tags - In general, Google figure out what your post is about, so don't worry too much about it. So my question is do I need to remove all tags from my blog or can I reduce the tag count to 5 alone? Currently I am using 15 tags to each post, is there any dis-advantage by adding tags like this? Let me know your suggestions? Thanks

Wordpress & trailing slash on domain name
Hi recently changed my site so it is based on Wordpress, got my preferred domain set in Google webmaster as www.domian.co.uk but since moving to wordpress my domain is now having a slash put on the end of it like www.domain.co.uk/ Most of the links going to my homepage do not have the slash on the end so am I right in thinking I should get rid of the slash from my site so I have one consistent url? If so any ideas how to banish the slash? Cannot seem to do it through the Wordpress general settings (despite preferred domain being set as www.domain.co.uk !) Thanks T

Keyword Stuffing in Alt Tags!
Hello, I have on a main page over 50 images. The first page i want to optimize it for MAINKW (let's say). Now, if i use in the alt tags "MAINKW KW1", "MAINKW KW2", "MAINKW KW3" ... "MAINKW KW50" then Google may say that i stuff the MAINKW in that page? Those images are reprezentative for main Categories and i have direct links to them from the main page with the anchors KW1, KW2...KW50.
