Hello. I would like to know if switching wordpress theme can in any way affect my serps. Can i lose rankings in SE in any way? Thanks in advance
It makes a difference, just not that much. content and the quality of (back)links still decide where you end up. but for layout of the page i'd check on the position of content (top/bottom of page, right or left), presence of a left sidebar and the position of the tagcloud and category links (before or after content), the menu link structure (beware of the use of 'hidden' divs) the presence of 'thank you' footer links (put 'em on nofollow), the place the tagline is displayed, use of extra anchor attributes (title, rel), use of css or html markup, divs or tables (tables can have more tags
as long as the code isn't changed much and your keywords are still in the right places it wont make much differences yes
Changing a theme that just changes the cosmetics of a site such as colors, font sizes and images would not have much effect on your site. The answer would be yes, it can effect your rankings, if by changing your wp theme your entire structure changes. Use seo-browser.com to see how your site looks to a search engine. If this changes then the rankings of your site could change as well.
you will get some much effect but not too much in serp.... ya your PR definitely loose / increase....
