When using ALT tags - are spaces, hyphens or underscores preferred by Google when using multiple words?
-
when plugging ALT tags into images, does Google prefer spaces, hyphens, or underscores? I know with filenames, hyphens or underscores are preferred and spaces are replaced with %20.
Thoughts?
Thanks!

When using ALT tags for images, it's generally best to use hyphens to separate multiple words in the text. Google and other search engines tend to interpret hyphens as word separators, which can help improve the accessibility and SEO of your web content. While underscores can also be used, hyphens are the more widely accepted and recommended practice. Spaces should be avoided, as they might not work as expected in all situations, as you mentioned, they can be replaced with "%20" in URLs. Using hyphens in ALT tags ensures better readability and consistency.

Google prefers hyphens (-) as word separators in ALT tags when using multiple words. Using hyphens helps improve the readability and search engine optimization of the ALT text for images. For example, if you have an image related to project management professionals, it's better to use "project-management-professionals" in the ALT tag rather than spaces or underscores. This practice helps search engines understand the content of the image more accurately. (PMP Exam Prep) (Project Management Professional)

When it comes to using multiple words in ALT tags, there isn't a strict preference by Google for specific characters like spaces, hyphens, or underscores. Google's algorithms are designed to understand various formats and interpret them accordingly. However, it is generally recommended to use hyphens or underscores to separate multiple words in ALT tags, as they can improve readability for both search engines and users. Using either hyphens or underscores creates distinct word boundaries and makes it easier for search engines like Google to recognize and index the content accurately. Ultimately, the most important aspect is to provide descriptive and relevant ALT text to enhance accessibility and user experience.

Google prefers hyphens to spaces or underscores in alt tags when using multiple words. This is because hyphens are more descriptive and easier for screen readers to understand.
For example, the alt text "black cat" is more descriptive and informative than "black_cat" or "black cat".

Google recommends using hyphens (-) to separate words in ALT tags when using multiple words. This helps improve the accessibility and SEO of your images by making them more readable and understandable for both search engines and users.

YES!!!!
Always use lowercase for filenames because if you use Upper and Lower (sometimes called camel case) for your internal and menu linking Google will crawl it and index the U&l. Then the fun begins when you have to match your sitemap to that!
-
1. File names- always use the hyphen.
2. Alt Text - use spaces and normal word structure. Ryan is correct on the technical intent behind the alt tag, but it can also be a good SEO tool, and you should treat those as exact phrase keywords. So nobody is searching for "city-bikes", they are searching for "city bikes". The alt tag should be what the user will put into google.
-
Yes, use hyphens for filenames, and lower case.
-
Thanks Ryan- so as with filenames, is it advantageous to us:
City-Bikes
or
City Bikes
with filenames, I am told preference is for city-bikes.jpg rather than "city bikes.jpg"
-
Ryan, it depends on your site design but you are correct.
Link Titles will appear when you hover your mouse over the link.
Alt tags are designed to display a text description for those who cannot see the image, such as visually impaired readers or crawlers. You can simply type as you would normally with spaces.
Alt tags do have a SEO significance, as do the image's file name. Both can be used to associate keywords or phrases with your web page, as well as the image search vertical.
-
It will probably show the link title if the image is wrapped in a link tag and you have no alt tag. Alt tags do have SEO significance - and they do show when you hover on an image. Use normal text
-
I am confused - I thought what you see when you hover is the Link Title - at least that's how my site has been functioning.
Does alt tag on images not have any SEO significance?
-
The Alt tag is primarily there for usaility - ie when you hover the user can see the alt information. Therefore write how you would write normal text

Multiple H2 tags
Is it advisable to use only one H2 tag? The template designs for some reason is ended up with multiple H2 tags, I realise if any think it's that each one is that are important and it is all relative. Just trying to assess if it's worth the time and effort to rehash the template. Has anyone done any testing or got any experience? Thanks

508 compliance vs good SEO re: Image alt tags
I'm currently in debate with our 508 compliance team over the use of alt tags on images. For SEO, it is best practice to use alt tags so that readers can tell what the image represents. However, they are arguing that these images should NOT have alt text as it doesn't add anything to the disability screen reader as the image text would be repetitive with the text on the page. I feel they are taking the "decorative" image concept in 508 compliance too far. It's intention is for images for bullets, etc that truly are decorative in nature and add no benefit to the reader. What is the communities thoughts on this? Have you ever run into scenario where 508 is attempting to ruin SEO? Usually the 2 play nicely.

Alt tag for src='blank.gif' on lazy load images
I didn't find an answer on a search on this, so maybe someone here has faced this before. I am loading 20 images that are in the viewport and a bit below. The next 80 images I want to 'lazy-load'. They therefore are seen by the bot as a blank.gif file. However, I would like to get some credit for them by giving a description in the alt tag. Is that a no-no? If not, do they all have to be the same alt description since the src name is the same? I don't want to mess things up with Google by being too aggressive, but at the same time those are valid images once they are lazy loaded, so would like to get some credit for them. Thanks! Ted

Number of images on Google?
Hello here, In the past I was able to find out pretty easily how many images from my website are indexed by Google and inside the Google image search index. But as today looks like Google is not giving you any numbers, it just lists the indexed images. I use the advanced image search, by defining my domain name for the "site or domain" field: http://www.google.com/advanced_image_search and then Google returns all the images coming from my website. Is there any way to know the actual number of images indexed? Any ideas are very welcome! Thank you in advance.

Meta Keywords: Should we use them or not?
I am working through our site and see that meta keywords are being used heavily and unnecessarily. Each of our info pages will have 2 or 3 keyword phrases built into them. Should we just duplicate the keyword phrases into the meta keyword field, should put in additional keywords beyond or not use it at all? Thoughts and opinions appreciated
