[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://moz.com/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

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?

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://moz.com/community/q/what-constitutes-keyword-stuffing

Site name in page title - leave it or remove it?
Hi all, Recently came across some authority blog (quicksprout to be precise) which stated that apart from main page, contact page, about us and some other generic pages, site name should be removed as it might produce duplicate content. example "How to blog | Example Site name" This mostly is the issue with tags and categories pages as it shows on Moz issues. Is that really a problem and site name should be taken off them? Thank you.

H1 tag positioning impact
Hello, I am currently working with a dev team to develop a new site. We have designed the title tags to sit below a banner image on each page but the technical team are insisting the h1 title tags must come above the banner for maximum SEO impact. I am sceptical about this, can anybody please shed some light and/or share any up to date resource on this? I have attached a side by side wireframe to illustrate the pages with the h1 tags in both positions. Thank you! HnWcLTx

How does Google handle read more tags in Wordpress
Hi Everyone I am wondering how Google handles the read more tag in Wordpress. I pasted the link to a blog post on Google and found nothing (domain.com/post#readmore). Then I paste the version without #readmore (domain.com/post) and found that Google indexed the page but with the option to click "read more" to read it. The full blog post is not in their index, just the version asking you to read more. Is this because Google hasn't gotten to it or is Google ignoring it. I am not sure but ideally I rather have the full blog post indexed, not the read more version. I am curious to whether this will cause duplicate content issues. What are your experience with this and is it advisable to use an alternate method for read more. Maybe with a Wordpress plugin. Thanks in advance.

Business Name is Meta Description
I would like to know what your opinion would be regarding the business name displayed in the meta description. Would you write your business name as: Business Name or BusinessName™ (no space with Trademark) I used MOZ example from here (Meta Descriptions Best Practice) and inserted the different business names. Welcome to Business Name in San Diego, California - the nation's largest urban cultural park. Home of 15 major museums, renowned performing arts venues... Welcome to businessname™ in San Diego, California - the nation's largest urban cultural park. Home of 15 major museums, renowned performing arts venues... I'm not sure which would be best for Google and other search engines. Thanks for your help.

ALT tagging images with keyword. What is too much?
I was wondering about the best practices of ALT tags in images. Say if you have an eCommerce site and you're on a product page. This product page has 5 images of the same product (different images), should you give every image an Alt tag with the keyword for that page? Or, is that keyword stuffing, and it would actually be best practice be to provide alt tags on just one image?

Can I place H1 tag anywhere on page
Hello, For those of you who use Magento you will know it is not SEO friendly. When you create a category or product, the name of the product or category then becomes the H1 tag. We sell mens business shirts. For example we have a product called 'White poplin classic fit' this is also the H1 tag, nobody is ever going to search for that term so I have had my developer create a new attribute that allows me to keep the product name as it is and let's me create a new SEO friendly H1 tag, for example 'White business shirt' However, placing 'White business shirt' on the page to be visible by the visitor does not look good on the page. My question is. Can I place the H1 tag anywhere on the page? I have some tabs like below. I am thinking of add a tab in between delivery and returns called more info and placing more seo keywords including the H1 tag in this tab. Will this be OK or will this be seen as black hat technique?

Generic domain for SEO versus Brand name
I am currently building a retail e-commerce site in a highly competitive area. We have a generic brand name; e.g. kitchen-knives.com and we also have another brand name, e.g. 'slycers.com' We have 3 options that I can see and I would like to know which is better for SEO. Build generic.com as a blog site. Link to brand.com 301 redirect from generic.com to brand.com. Use generic.com as anchor text in all links 301 redirect from brand.com to generic.com . Use generic.com as anchor text in all links Also, if there are other better options, then I would appreciate the input! thanks

Image Optimization - File Name Important?
I am currently working on a site with 100+ recipes that all have image file names that are relevant, but not optimized for keyword purposes. I'm wondering - from an SEO perspective - would it be worth my time to go back through all of the images and rename them with keywords in mind? On my own site I have always done this as a "best practice" but I'm curious - does it make a difference to search engines? Does anyone have any recent research/experiences that they would like to share? Thanks!
