JavaScript page loader - SEO impact
-
Hello all,
I am working on a site that has a bizarre page load system. All pages get loaded trough the same Javascript snippet, for example:Changing the values in the form changes the page that is loaded.
The most incredible thing is that, against my expectations, pages do get indexed by Google.
My question is: "Does loading pages dynamically using JavaScript affect the overall SEO performance?"Why are pages getting indexed?
Thank you for shedding light on this.
Cheers

Hi Luca! So sorry for the wait. Yes, Google is able to load, crawl, and index pages written in Javascript. There are mixed reports as to how well, exactly, but your research is correct.

I have done my homework researching.
As a matter of fact since 2010 Google can crawl and execute JavaScript links, therefore the pages will be indexed and ranked exactly as static HTML pages.It would be nice to have confirmation on this

# Tag - opacity and SEO impact
Hello,
Technical SEO | | Tiffany_Barn
I have a query animation 'fade-in-up' on my website: tiffanybarnard.com which moves the H1 tag slightly and fades it in from zero opacity to 1. Will this affect the SEO value of the H1 tag?
Thank you!0 -
Page Rank Flow
I wonder if someone can help me understand clearly page rank flow. If we have a website with a Home page, Services, About and Contact as a very basic website and the page rank will flow to each of those pages from the Home page (i'm not including internal linking between pages or anchor text from the home page content - this is a question purely about home page flow via the main navigation). If the Services page had 3 drop down pages. Would the home page rank also flow to each of these or is it going to the Services page which then distributes it to the three drop down. So instead of Home page rank flowing to 3 pages 33% each - it is flowing to 6 pages 16.6% each. Or is it flowing to 3 pages - 33.3% then the Services pages get a third of 33.3% ->10.1% I know this is simplifying it all a great deal- but it is the basic concept I am trying to grasp on this simple example. Thanks

Static or dynamic category pages for seo
Hi, I'm developing an accommodation site with a limited number of properties in 8 categories. I had been looking at making the properties blog posts and then using category function to show lists but its going to require a lot of customisation and I have seo concerns about the dynamic content as the category page is crucial. As I don't have a lot to add and listings will remain the same my latest thought was to create all as pages. However if I create a page with a list of 12 properties on a category page is there anyway of adding some sorting criteria to that page (would be 7 options - swimming pool, near beach, on site creche, budget, mid-range, luxury) Thanks for any tips Neil

Will removing the trailing slash impact my SEO?
Hi there, We have a company website based on Wordpress. I just noticed that under Settings > Permalinks I can configure the look of the URLs and even remove the trailing slash. We have about 2-300 pages online. If I remove the trailing slash now, will that negatively impact our SEO in anyway for existing pages? Thanks!

How Does Google's "index" find the location of pages in the "page directory" to return?
This is my understanding of how Google's search works, and I am unsure about one thing in specific: Google continuously crawls websites and stores each page it finds (let's call it "page directory") Google's "page directory" is a cache so it isn't the "live" version of the page Google has separate storage called "the index" which contains all the keywords searched. These keywords in "the index" point to the pages in the "page directory" that contain the same keywords. When someone searches a keyword, that keyword is accessed in the "index" and returns all relevant pages in the "page directory" These returned pages are given ranks based on the algorithm The one part I'm unsure of is how Google's "index" knows the location of relevant pages in the "page directory". The keyword entries in the "index" point to the "page directory" somehow. I'm thinking each page has a url in the "page directory", and the entries in the "index" contain these urls. Since Google's "page directory" is a cache, would the urls be the same as the live website (and would the keywords in the "index" point to these urls)? For example if webpage is found at wwww.website.com/page1, would the "page directory" store this page under that url in Google's cache? The reason I want to discuss this is to know the effects of changing a pages url by understanding how the search process works better.

Determining When to Break a Page Into Multiple Pages?
Suppose you have a page on your site that is a couple thousand words long. How would you determine when to split the page into two and are there any SEO advantages to doing this like being more focused on a specific topic. I noticed the Beginner's Guide to SEO is split into several pages, although it would concentrate the link juice if it was all on one page. Suppose you have a lot of comments. Is it better to move comments to a second page at a certain point? Sometimes the comments are not super focused on the topic of the page compared to the main text.

How much impact does bad html coding really have on SEO?
My client has a site that we are trying to optimise. However the code is really pretty bad. There are 205 errors showing when W3C validating. The >title>, , <keywords> tags are appearing twice. There is truly excessive javascript. And everything has been put in tables.</keywords> How much do you think this is really impacting the opportunity to rank? There has been quite a bit of discussion recently along the lines of is on-page SEO impacting anymore. I just want to be sure before I recommend a whole heap of code changes that could cost her a lot - especially if the impact/return could be miniscule. Should it all be cleaned up? Many thanks
