Can i use base64 images (URI) for better SEO performance - faster site loading?
-
Hi,
Do you think the use of image data URI is SEO friendly? I got 20 JPG icons on each site, but use too many HTTP requests. So can i use base64 (URI) images for my small icons?
Thank you for answer!

There are pros and cons to it. I would just make sure you have some good caching rules in place and let it load once and be done with it. Realistically Google is not going to refuse to serve your page because you ran 20 http requests for some icons. That would be silly.
I try to remember that at the core of all things search related every search engines holy grail is the perfect result for your search query. In one of Matt C's videos they hit the subject of on-page factors versus content and he said they would overlook a lot of things in order to deliver the better result to the query. So for SEO purposes cache it and get to that content rocking. -
Hi,
There are some differing opinions on the benefits of using base64 images to reduce http requests. From an seo point of view I don't think it will make much of a difference one way or the other if you are only talking about 20 icon images, but from a performance point of view I would use css image sprites which also reduce http connections and are (in my opinion) easier to maintain.

Not using alt tags for decorative images?

Why are my blog slideshow images not indexed?
I'm managing a design blog hosted on WordPress. Each "design project" article includes a slideshow with additional images (and captions) for the project - these are images and text not found in the article itself. Every slide has the same page path as the article, but a different query param at the end. So if the article is /article the first slide would be /article?slide=1 for example. I'm having two issues: The slideshow images don't seem to be getting indexed. Screaming Frog reports duplicate meta descriptions and title tags for each slideshow page (same meta as article). I want to do what's best overall from an SEO perspective. Having the slideshow images show in Google image search is a must. And having the captions indexed might help too? But I want the Google image results linking to the article and not the individual slideshow pages. And I don't want duplicate meta issues. What's the best thing to do? Submit a sitemap that lists both article and slideshow images? "Rel canonical" the param'd slideshow urls to the base article url (not sure this makes total sense, since slide content is different from the article)? Get rid of slideshow altogether and put images in body? Some combo of these? Hopefully this makes sense. Any thoughts appreciated!

Vimeo Pro, video SEO and rich snippets
Hi All, we are producing product demonstration videos. One major aim with these videos is to help our rankings for these specific product pages and associated keywords... and to get rich snippets displayed on Google results pages against our listing. We have used schema.org markup in the product pages body code along with / next to the embed vimeo video code on the product page in order to hopefully get us rich snippet listing... we used schema.org markup as this seems to be the main current markup for rich snippets we have hosted the video via Vimeo Pro so that it is served quickly and not affected by speed of our hosting server or any possible bandwidth issues on our hosting server and ensure sthat the traffic comes to our site pages rather then Youtube or similar Vimeo Privacy settings for the video have been set so that we have not allowed it to be embed anywhere except for our own domain and the video is not displayed on Vimeo.com to ensure that the video is not duplicated anywhere else... so that this is unique content on our own site for maximum value for our domain We have used the "old code" from Vimeo Pro for embedding the video on our product page rather than the current iframe code as from what i understand Google cant follow very well and doesn't necessarily trust content displayed in iframes. Video and schema.org markup code used is on product page is: <div itemprop="<a class="attribute-value">video</a>" itemscope itemtype="<a class="attribute-value">http://schema.org/VideoObject</a>"> <p ><strong>Watch our <span itemprop="<a class="attribute-value">name</a>">Click 7 Lite Duo demonstrationspan>:strong>p> <meta itemprop="<a class="attribute-value">thumbnailURL</a>" content="<a class="attribute-value">http://www.3wisemonkeys.co.uk/img/products/nextbase-click-7-lite-duo-thumb.jpg</a>" /> <meta itemprop="<a class="attribute-value">duration</a>" content="<a class="attribute-value">T2M23S</a>" /> <span itemprop="<a class="attribute-value">description</a>">A product demonstration showing what's included in the box when you buy a Click 7 Lite Duospan>...:<br /> <p align="<a class="attribute-value">center</a>"> p> <p align="<a class="attribute-value">center</a>"><object width="<a class="attribute-value">500</a>" height="<a class="attribute-value">281</a>"><param name="<a class="attribute-value">allowfullscreen</a>" value="<a class="attribute-value">true</a>" /><param name="<a class="attribute-value">allowscriptaccess</a>" value="<a class="attribute-value">always</a>" /><param name="<a class="attribute-value">movie</a>" value="<a class="attribute-value">http://vimeo.com/moogaloop.swf?clip_id=67392721&force_embed=1&server=vimeo.com&show_title=1&show_byline=1&show_portrait=1&color=00adef&fullscreen=1&autoplay=0&loop=0</a>" /><embed src="[http://vimeo.com/moogaloop.swf?clip_id=67392721&force_embed=1&server=vimeo.com&show_title=1&show_byline=1&show_portrait=1&color=00adef&fullscreen=1&autoplay=0&loop=0](view-source:http://vimeo.com/moogaloop.swf?clip_id=67392721&force_embed=1&server=vimeo.com&show_title=1&show_byline=1&show_portrait=1&color=00adef&fullscreen=1&autoplay=0&loop=0)" type="<a class="attribute-value">application/x-shockwave-flash</a>" allowfullscreen="<a class="attribute-value">true</a>" allowscriptaccess="<a class="attribute-value">always</a>" width="<a class="attribute-value">500</a>" height="<a class="attribute-value">281</a>">embed>object> p> div> Page this code is used on: http://www.3wisemonkeys.co.uk/proddet.jsp?id=2016&cat=1 Could anyone confirm whether the above seems to be what we need to do / should be doing to get the most value from these videos for helping our web site rank better with Google / search engine results pages as well as getting rich snippets displayed? Lastly does the above code seem correct and include all the necessaries for rich snippets? Thanks for any pointers.

Local SEO: Links with the citations so should I slow down?
Hello, There seems to be some nofollow and dofollow links building as I add structured citations. Is this a reason to slow down the building citation process if you want the links to count? Do they help organic SEO?

Is a website with no images really a good idea?
I have a client who doesn't want to use any images at all on her website. It's a local hvac service provider. This thought has never even crossed my mind before. Who wouldn't want pictures? I know image optimization is important, and my mind keeps telling me that images are important for a good site and good user experience, but are they really necessary? I want a second opinion before I advise against not using any images.
