Mass changes of titles and descriptions can cause issues?

[markovald]

I have a big website with all the titles and desc NOT optimized...if i change all of them in one day this can cause seo issues on my site? It's okay to do that?

I have a big website....

If the current titles and descriptions are "close" but not "optimal" then small tweakings will probably not be a problem.

But... my concern is that you have a large website and plan to do this job in one day.

I often spend a bit of time on each title and description.  I want a title that presents the the page for the proper keywords (so I do a bit of KW research).  I also want a title that elicits clicks or presents a value proposition (so I spend more time on that).  Then I want a description that personalizes the article to the search audience, or presents secondary keywords and secondary propositions (again, more time).

These things can take some time, but, if done deliberately and well, they can multiply your traffic potential beyond what you might get from a "slap them on quickly effort".

So, I would spend 1/2 day per week over the next couple of months on this job.  I would do the pages with the highest anticipated value first, then work my way to the less important pages, while keeping an eye on the performance of those most important pages.

EGOL sir, you probably nailed it!

Whenever creating titles and descriptions you have to think about two areas

1. Your search audience
2. Search Engine Rankings

Id I would be at your place, I would list down all the important keywords in one document and then map the keywords on different pages of the website accordingly. Once done and I know what keywords I should be placing on each URL/page, I will move accordingly.

Once I have keywords mapped, next thing is to divide the pages as per the priorities. Important, Less Important and rest of the pages

Start with important pages, than move towards less important pages and then the pages that are on the website but not your priority at all.

As EGOL said, dedicate some time in your day may be half hour everyday (if you have another person to do the job in that case its different) and get the job done. This way it will be more efficient and closer to what your audience is looking for

Hope this helps!

Egol and Moosa are spot - a couple of things to add.

I suggest do not first work on your most important pages first. With the new search analytics in WMT's you can learn a lot about your website - easy and quick now to monitor page change outcomes. Train on a few lesser important pages, some might have more traffic, then go to your most important pages.

If you only change the meta description - monitor CTR on WMT's. If you change the title and meta description - spread sheet both Clicks and CTR. When changing Title often the page rank and even the CTR can drop but total clicks increases. After you have optimized a few pages and found out why people click, comfortable with the results, made your mistakes:-

Then armed with that knowledge focus on your primary pages, and you will do it with confidence.

We do alot of this and to jump to the most important pages first and "practice" on them, is not something we recommend. We often think we know, but every site has nuances and customers do not do exactly as we anticipate.  We got burnt a few times doing the important pages first as that is what the client always wants...  You may get it right, but why risk it. It is a ten day delay, if all goes well.

Hope this assists.
