Should I really worry about warnings¿?

[levalencia1]

I have about 300 errors about duplication of content.

But I also have like 3000 warnings for:

2500, too many links on page

2000, meta title longer than 66 characters

200, too long url.

I have analyzed my competition, and 90% of them have also too many links on pages and long meta titles.

Are these 2 really factors to improve my google ranking?

My site is: theprinterdepo.com

and my main keywords are printers, refurbished printers, laser printers

Yes the warning do matter they are trying to inform you of items you should pay attention that can impact your rankings on search engines.

1.) The number of links per page:  having to many links per page can appear like spam during a search engine crawl  therefore effecting your ability to rank well.   Do you really require that many links per page?  Are most of  these links actually ever being used? I suggest you use site overlay in Google analytic and pin point which of those link are most valuable to your website and think about reducing the ones which are rarely clicked on.

2.) Having such long title tags is a waste of time as search engines will certainly not parse titles longer than 70 characters  any longer than this are cut off and not displayed .  Again these are  factors that will appear like spam injection in your title.

3.) Long URL are also unavoidable for spam and keyword injection reasons i would suggest shorter URLs.

Overall if your site is producing the errors you mentioned above  I would seek to resolving them as they are not good in terms of search engine rankings or  pleasant for visitors to your website.
