What to consider when deploying a complete website redesign for search engines?

Question

I am planning a redesign of my page (4-5 years old with pagerank 3-4). There will be no URL changes, which means that the same content will remain under the same URL. But I'm still worried because I heard that changing the structure of the HTML throughout the page can have some effect, mostly negative. But there is no way to change the design and layout of the page without changing the structure of the HTML.

Could you summarize everything you need to consider when redesigning a website with a search engine?

I could dwell on some details, but basically check your site with this to get a detailed analysis: http://nibbler.silktide.com/ Before and your test site (Preferably on a test domain, i.e. .mywebsite test .com).

The main things you do not need to do: Do not use html tables for anything other than displaying data in a grid, do not use semantic html where it is not needed, this is used to emphasize important things.

Make sure your html is valid and you have all the relevant meta tags in place in accordance with the w3c standard that you choose for your design.

Content is key, keyword density and topics are important, do not dilute the page if you intend to add a new page.

Be sure to add a sitemap and submit to all search engines and get a robots.txt file pointing to a local XML sitemap .

For everything that you did not understand, I said google phrases in bold and you will find more detailed information about the implementation.
