          I am trying to diagnose a massive drop in Google rankings for my website and noticed that the date of the ranking and traffic drop coincides with Google suddenly only indexing about 10% of my images, whereas previously it was indexing about 95% of them.

          Wondering if addition of lazy load script to images (so they don't load from the server until visible in the browser) could cause this index blocking?

            Although Google can now get to js, I would still be nervous on choosing a theme/CMS  that is using lazy loading.

            According to John Muller from Google:

            “Is Googlebot able to trigger lazy loading scripts- lazy loading images for below the fold content” – “This is a tricky thing.”

            On lazy loading images John says  “test this with Fetch as Google in Webmaster Tools” and “imagine those are things that Googlebot might miss out on.”

              Option to index images? Or option to index image attachment pages? I've not seen the first, but I have de-indexed attachment pages because I didn't have time to make them all unique. Where do I find the option to not index images? And why would that make SEO scores better?

                Yes - could be. You need to use Google SearchConsole Fetch&Render tool to identify are images is loaded at all.

                Also note that some of lazy loading tools used data-src ( https://github.com/dinbror/blazy ), other pagespeed_lazy_src ( https://developers.google.com/speed/pagespeed/module/filter-lazyload-images?hl=en ) and third data-img-src and many others. You need to check what attribute your tool is used and check are images crawlable and indexed.

                You need to check also Qazy - https://github.com/qnimate/Qazy yet-another-lazy-loading tool without negative SEO impact because images are loading from src attribute. And this is explained here: http://qnimate.com/lazy-loading-images-and-its-seo-impact/

                So - yes this negative impact could be caused from images lazy loading too.

                  Hi!

                  Big images reduce the speed on the page and speed is a(n increasingly important) ranking factor. You could use Page Speed Insights to see your overall  site speed or the speed of a specific page.

                  Within Worpress there is also a setting to index images as a search result or not. On my site it was on and once turned off within a few weeks my overall scores increased so maybe that helps aswell.

                  Good luck!

                  Tymen

                    Affect of ™ and ® in title for SEO

                    I am looking at adding the trademark and rights reserved symbols to some of my titles. I think this might help with click through rate. From what I have found, this shouldn't have an affect on SEO unless it makes the title too long. Is this correct? Stephen

                    Hi, I'm currently adding alt tags to my images but the Yoast SEO plug in in Wordpress states on all my pages “No images appear in this page, consider adding some as appropriate.“ while I do have images on my pages. What could be the problem? Best, Rik

                    Will changing a URL negatively affect ranking?

                    Hello Mozzers, We would like to change the URL for a page on our website which ranks well for some our keyphrases/words. We are hoping the change of URL, through the addition of an additional keyword would help boost the rank of that URL further. At the moment out page gets 2 x A and 2 x B 1xF on the MOZ page rank tool using 5 keyphrase/word variations . One phrase ranks 4, one ranks 3 and the other 3 are 'not in the top 50' Our plan was to change the URL, using SHF404, and use 'Fetch' in the Google search console to re-submit the page to Google. Appreciate you can't give any guarantees how Google will behave, just wondered what your thoughts were on the wisdom of changing the URL in the first place? Thanks Ian

                    Image titles and alt tags for multiple images

                    I'm hoping some of you may be able to help me understand the best way to optimize my image titles and alt tags for a specific situation. I'm working on an interior design website and they have hundreds of pictures. each of their projects has about 10 pictures. Is it best for me to us the key phrase in each title and tag? or is that to repetitive? here is what I mean: A project called "urban interior design" all images are of urban interior design, just different angles and features, so my initial idea is to just have each image title like this: Title: "urban interior design dinning area" Alt: "urban interior design dinning area view" Title: "urban interior design living room" Alt:"urban interior design living room couch view" Is this the best way or will it actually hurt my ranking with too much exact keyword use? Thanks for your help!

                    Does Google index dynamically generated content/headers, etc.?

                    To avoid dupe content, we are moving away from a model where we have 30,000 pages, each with a separate URL that looks like /prices/<product-name>/<city><state>,  often with dupe content because the product overlaps from city to city, and it's hard to keep 30,000 pages unique, where sometimes the only distinction is the price & the city/state.</state></city></product-name> We are moving to a model with around 300 unique pages, where some of the info that used to be in the url will move to the page itself (headers, etc.) to cut down on  dupe content on those unique 300 pages. My question is this. If we have 300 unique-content pages with unique URL's, and we then put some dynamic info (year, city, state) into the page itself, will Google index this dynamic content? The question behind this one is, how do we continue to rank for searches for that product in the city-state being searched without having that info in the URL? Any best practices we should know about?

                    How many keywords max can I optimize each page for?

                    I don't want to over optimize by doing 1 keyword per 1 page, but then if I do more, seomoz on-page tool report doesn't give an A grade for each keyword I optimize. I usually optimize for max 3 keywords that are very closely related, meaning they use the same words.  Ex. dentist los angeles, los angeles dentist, dentist in los angeles Am I on the right track or what's your recommendation? Should I create different landing pages for each keyword?
