Migration from HTML to Wordpress - SEO Implications?
-
I am in the process of having a wordpress site developed to replace my current HTML site. (I currently have my website in html and a blog in wordpress in a sub directory). I am doing this in phases to try and preserve as much of my good rankings as possible. My first phase is to replicate my site with the exact same pages, meta data, and site structure. I'm hoping that google will see this as not much change and not change my rankings for the worse. I also made it a goal that my site speed tests be at least equal to what they are now. We will have to 301 all of the URLs however since it will be going from /example.html to /example. I believe my blog will also need to move into the root directory as well, so I need to 301 all of those pages.
I plan to wait a couple months for Phase 2. Phase 2 involves replacing old content (photo galleries), and introducing new content (virtual tours, videos, new pages, etc.) One of my reasons for moving to wordpress is to keep up with current trends a little easier since I have very little time. (I am owner, website maintainer, SEO - all on my own).
My question here is three parts. 1. Do you think this strategy will work to preserve my current rankings? 2. Do you have any lessons learned or advice to share with me to make this as smooth as possible? 3. Do I really need to wait to add new content? I might get antsy and want to do it sooner!

Thank you in advance!

I think it's a very dangerous idea to migrate your website to another platform on your own. No matter how diligently you do it, you won't be able to maintain your position in the search engines. I say this from personal experience.
It is better to contact the professionals. This team is excellent at helping you migrate your site to WordPress (Heidelberg). -
For lengthy-tail positions, typically you'll no longer see a dramatic drop. In truth, typically no drop in any respect. For some of the greater competitive positions, you most probably will see a mild loss. Some businesses do see a dramatic drop--but maximum probable due to different elements like microphone reviews. Over time, count on to regain the positions of the one in case you recognition on UX.

Thank you! I do plan to keep the internal linking the same, except the URL will change of course. The site structure is staying the same, except the blog will be moving to the root directory instead of being in a sub directory.
Thanks for the advice on the XML sitemap!
-
Good to know! Most of my searches are very specific, so I would say they are long-tail keywords.
-
I'd say for any drops, 4-6 weeks is pretty reasonable. To agree with Kevin again, most drops are user error (not doing redirects correctly etc) or as he said, major design/UX changes.
You may want to also be sure to implement an XML sitemap right away, and submit it to Search Console.
Also try to keep your internal linking the same where possible (menus, breadcrumbs, sidebars etc).

For long-tail kw positions, generally you will not see a dramatic drop. In fact, many times no drop at all. For some of the more competitive positions, you most likely will see a slight loss. Some companies do see a dramatic drop--but most likely because of other factors. Over time, expect to regain those positions if you focus on ux.
Dan's comments were spot on. I typically launch early on a saturday morning (2am or so) and make sure everything works. If you do launch, and the site blows up, you can always switch the 'a' record to the old site (assuming it is at a different server) and troubleshoot.

Thank you, this is also very helpful! I've never used Screaming Frog SEO Spider, so I will look into this! As for scheduling, that's why I am doing this in January. We are a tourism business, so we will peak in Feb / Mar. I'm hoping that 4-6 weeks will be enough to bounce back if we drop any. I do run Google PPC as well, so if it does drop, I'll have to up my PPC campaign. How long does it usually take to settle back out?
-
Thank you! That is very helpful. I will test the 301s! And thanks for letting me know to expect a 15% loss. Will that come back over time? I don't even want to lose one spot! Haha!

Hello! Kevin pretty much answered it but just wanted to add a few things:
1. To prioritize pages to check etc, export your top landings pages from Google Analytics. Run those through Screaming Frog SEO Spider in list most to check status codes and be sure they redirect. This way you're accounting for the highest trafficked content as a priority.
2. Schedule the exact switch for a low traffic time of day/week to be cautious.
To reiterate what Kevin said - having working redirects is the essential component here!
-
1. Do you think this strategy will work to preserve my current rankings? Yes, as long as the 301's are done properly and expect around a 15% loss.
2. Do you have any lessons learned or advice to share with me to make this as smooth as possible? Make sure to test the 301's before hand. Specifically, change your hosts file to the ip of domain. Next, go to google and do a site:yourdomainname.com and click on each result and make sure the redirects are done properly. Also, pay attention to Google Search Console, Analytics and etc for 404's and such. Make sure your .htaccess file isn't huge and add a new sitemap and etc.
3. Do I really need to wait to add new content? I might get antsy and want to do it sooner!
No, but I would wait until the dust settles (more of a personal preference) as you need to focus on the launch.Sounds like you have it handled! It's all in the prep and how to handle issues post-launch in a time-sensitive matter. Good luck!

How do elements that are displayed when scrolled impact SEO?
Hi, We are wanting to implement Animate.css and Wowjs on our site and were concerned about the SEO impacts. Basically when the page is loaded, if the element is not within the viewport then the HTML tag (i.e. div tag) have a style="visibility: hidden" and once the element is within the viewport it will change to have style="visibility: visible". Would having the style="visibility: hidden" negatively impact SEO?

Problems preventing Wordpress attachment pages from being indexed and from being seen as duplicate content.
Hi According to a Moz Crawl, it looks like the Wordpress attachment pages from all image uploads are being indexed and seen as duplicate content..or..is it the Yoast sitemap causing it? I see 2 options in SEO Yoast: Redirect attachment URLs to parent post URL. Media...Meta Robots: noindex, follow I set it to (1) initially which didn't resolve the problem. Then I set it to option (2) so that all images won't be indexed but search engines would still associate those images with their relevant posts and pages. However, I understand what both of these options (1) and (2) mean, but because I chose option 2, will that mean all of the images on the website won't stand a chance of being indexed in search engines and Google Images etc? As far as duplicate content goes, search engines can get confused and there are 2 ways for search engines

to reach the correct page content destination. But when eg Google makes the wrong choice a portion of traffic drops off (is lost hence errors) which then leaves the searcher frustrated, and this affects the seo and ranking of the site which worsens with time. My goal here is - I would like all of the web images to be indexed by Google, and for all of the image attachment pages to not be indexed at all (Moz shows the image attachment pages as duplicates and the referring site causing this is the sitemap url which Yoast creates) ; that sitemap url has been submitted to the search engines already and I will resubmit once I can resolve the attachment pages issues.. Please can you advise. Thanks.0 -
WordPress Category page title h1 or h2
Hi friends, I know this is a minor technical change, but we are in an extremely competitive market and I don't want to have any points against us. On our WordPress Category pages i.e. http://www.domain.com/category/�tegory-title%/ I looked at the code behind the the Title of the category page, which is "Browsing: %Category Title%" The code is an h2. I look at the posts in the category archive below, and those are also h2's. The theme preview is here and you can click on Entertainment - Reviews to see exactly what I'm referring to - http://themeforest.net/item/smartmag-responsive-retina-wordpress-magazine/full_screen_preview/6652608 I changed the code for the "Browsing: %Category Title%" to h1, which I believe is more consistent and standard formatting. 1. Is this a correct technical on-page optimization? 2. Would it be beneficial to remove "Browsing"?

How to optimize SEO value of links in a calendar
Hi All- I am building a website about outdoor activities (cycling, kayaking, hiking, etc.). The site will most likely be built with either Joomla or Wordpress. A key piece of the site will be a calendar of upcoming events. The calendar will list the basic attributes of each event like date, time and location. However if an event has a webpage of it's own I will also include a link to that page in the details of the event. My question is: How can I create a calendar that will capitalize on the SEO value of the links included in the event descriptions? I've noticed many similar sites put events into a Google calendar and then embed the Google calendar into their webpage. In that situation would Google even see any external links included in the descriptions of the events? Thanks in advance for any input. -Chris

Old site to new WordPress site - Client concerned about Yahoo Ranking
Hello, Back Story I have a client (law firm) who has a large .html website. He has been doing his own SEO for years and it shows. I think the only reason he reached out to a professional is because he got a huge penalty from Google last fall and fell very far down in rankings. Although, he still retains a #1 spot in Yahoo for his site for the keyword phrase he wants. I have been creating a new WordPress theme for the client and creating all new pages and updating the formatting/SEO. From the beginning I have told the client that when we delete the old site and install a new WordPress site (same domain name, but different page hierarchy) he will take a bump in the search engines until all the 301 redirects get sorted out. I told him I can't guarantee any time frame of how long the dip in SEO will last. Some sites bounce right back while others take longer. Last week, during a discussion, he tells me that if he loses his #1 ranking on Yahoo for any length of time he thinks he will go out of business. Needless to say I was a little taken back. When it comes to SEO I use best practice techniques, do my research, stay on top of trends but I never guarantee rankings when moving to a new site. I'm thinking of ways I can help elevate any type of huge SEO drop off and help the client. Here is what I was thinking of suggesting to the client and I would love some feedback. Main Question He has another domain he isn't doing anything with. It's pretty much his domain name with pc added. I was thinking about using that domain to create a simple 1-2 page WordPress website with brand new content (no duplicate content) aimed at attracting his keyword phrase. I would do as much SEO as I could with a 1-2 page site and give it a month or so to see if this smaller site can get into the top #10 in Yahoo, or higher. Then, when we move the site he will still have a website on the first page of Yahoo for his keyword phrase. I hope I explained it clearly 🙂 I would be open to any suggestions anyone may have. Thanks

Site Activity, SEO, and behind login
I have a site that provides online education and as such, most of the user activity happens behind a login. This has me thinking about potential SEO impacts with a few questions that maybe someone could lend some light on: How important is activity (above just search activity) to the search engines Would it help to enter these pages, even though they're behind a login, into GA as we have with the front-end of the site Does a subdomain make a difference (right now we implement the course as a subdomain of the main site Lastly, as I was looking at compete.com, I am wondering how they get these use statistics?

Drop Down Menus & SEO?
Do these typically have a negative impact on SEO? I know this is kind of a vague question, does it make it harder to spider? Are there SEO friendly ways of coding these? There are so many sites out there that have these, so I've got to assume it's different on a case by case basis.

Wordpress vs. mvc framework
What's the benefits of choosing an mvc framework such as codeigniter or cakephp over wordpress? Wordpress has so many plugins, and a universally known UI for customers, it just saves a ton of time. However, a lot of the 'big guys' like SEOmoz and Distilled(?) use Cakephp and other mvc frameworks so it has me wondering what the benefits are...... anyone?
