I recently read a forum post where this person said that he updated and redesign his old site recently (CSS, tables removed, cleaner code etc) and his site's rankings went down. This is kind scaring me a little as I am intending to make some changes to my site. Shouldn't all this and SEO work onsite increase your rankings. Any chance it would affect it?
Someone then responded to that forum stating this:
- understand that your OLD site structure etc. became trusted by Google and other search engines (this is debatable to some but) and so now you need to build this up again.
Is this true? If so should I make changes stage by stage and slowly?
I don't know if there is a polls to see if SEO work onsite has ever had any negative effect on a site's rankings? I suppose the exercise to optimize a site should increase rankings. I am aware of not messing too much with pages that rank well already and will do 301 redirects properly, fix canonical issues, add a sitemap etc. Just want to be very careful to ensure such a thing never happens.
I guess a lot of you here do SEO work for your clients. Has anyone ever had such an issue?
