There are plenty of options available in the market when it comes to chossing a CMS for your website. This also resulted in to situations such as sudden shift of momentum with the development phase of a particula CMS or simply a drop in the popularity or usage of one. In such cases there is no option but to shift from one platform to the other. SEO is a gradual process and one must consider the effects of shifting platform on it.
Following are some points to consider
1. We should not change HTML mark-up, site structure, and URL structure or else the rankings will be influenced by this change.
2.Keeping the domain name the same is good but if you do not do 301 redirects from the old URLs to the new URLs there will be impact on SEO.
3. Exactly we don’t know how Google ranking algorithm works but Search engines gives rank to pages not the website. So if your content moves to a new URL and you do not do a 301 redirect from the old URL to the new URL you are starting from start and your rankings will almost drop.
4. While switching from one CMS to another, we should follow these guidelines:
• No content should be deleted during the process of redesign.
• Every page on the old site should have the same URL as that page on the new site
• Redirects should be the SEO friendly 301 type.
5. If you are changing domain name, top referring link sources should be identified from web analytics and contacted, to change what URL they’re linking to.
6. Pages that cannot be mapped need to be dealt with using custom 404 error pages.After the CMS and site design and redirects have been implemented, it’s important to continue monitoring web analytics for broken links and 404 errors so they can be fixed.
7. Perform an inbound link analysis as it is important for building SEO power. If you are changing URL structure, you will face a huge risk of losing your inbound links. Understand the links, know the pages which are linked to you and where exactly they are linking and as said above use 301 redirects.
8. Always make sure that Google bots can crawl and index your site, we can do this by creating a sitemap.xml file. Although we have 301 redirect, but Sitemap can give Google more specific information as how the site is structured.
9. Inform Google about site redesign. Go to webmaster tools, there you can find Change of address tool. Click on the little gear icon and there the site name should appear in select a site list. If doesn’t then go back and verify your website.
10. Audit the site as you need to know which pages your search engines like and which not. This can help you spot problems or errors and tells you which areas or pages must be focused. Please feel free to share your thoughts in the comment section below.
